134 Royalty-Free Audio Tracks for "End Of Time"

An Edison "Perfected" Phonograph cylinder recording of The Lost Chord (composed 1877) by Arthur Sullivan (1842-1900), played on piano and cornet. One of the earliest surviving recordings of music; was played at the press conference that introduced the phonograph to London on August 14 1888. Cuts off slightly before the ending of the song. The recorded version is somewhat abridged (a middle section has been cut, possibly due to time constraints). Overall a well-preserved example of wax cylinder recording technology. Length: 2:07

I recorded this many years ago on an imac g3 in 2008, the sound was recorded using the imac headphone jack into my desktop pc at the times audio in. I ended up doing this as my dsl went down for several days and i managed to get netzero working. I then uploaded the video to youtube where it has received over 10 million views. Https://www. Youtube. Com/watch?v=gsnar6fruo0. In 2012 a wonderful poster was made by oona räisänen, if you want a technical breakdown of what's going on in my audio have a read. Http://www. Windytan.

A recording of a typical busy, yet peaceful later afternoon sound-scape of a small midwestern town at 5:30pm on a weekday. This was recorded on tuesday may 24th, 2016 using the marantz pmd661 and two sennheiser me66 microphones. . . True stereo recording. You will hear the delightful sound of neighborhood kids playing a friendly - or sometimes not so friendly - game of wiffleball which adds to the reflective nature of this recording. The trilling bird calling towards the end of the recording is the beautiful little, rusty-capped chipping sparrow. These chipping sparrows converge on the midwest around this time and their calls can be mistaken as an insect. Enjoy this summer 2016 recording and maybe it will trigger wonderful, innocent memories of your own childhood.

The ambiance of the famous strasbourg christmas market, known as one of the oldest in the world (first edition took place in 1570) and the city's biggest touristic event, gathering thousands of people downtown for one month at the end of every year. I took my zoom h2n in different places, capturing a slightly different mood each time. Expect lots of crowd sounds, background music, street atmosphere and. . . A lot of different languages (french, german, spanish, english. . . . All recordings made in ms stereo mode (120° setting).

Circle of 5ths loop compiled on a 2015 macbook pro using field recordings. Tempo / time sig:24 bars of 3/4 timing with each bar lasting 2. 5s. Or 12 sets of 6/8 at 5s per bar with a total length of 60s. Filters:hipass pumped at 60hz, -5db. Lopass pumped at 1200hz at -6db. Delay set to 0. 05s at 600hz with a 60% wet mix. Arranged with the tonic 5th as a constant with the last (fifth) 5th in the circle, starting and ending with the tonic. Second 5th enters in 5s, third in 15s and the fourth in 25s as the fifth stops. The fifth 5th begins to fade back in after 10s of silence, which begins the process of the second, third and fourth fading out in that order. The fifth 5th is at full volume as the loop turns, as is the tonic. The mood changes noticeably as each consecutive 5th begins, and changes again as the following 5th joins the loop.

This was captured from last year. I thought my recorder wasn't working properly because when i checked the recording, i couldn't find the file. The time/date stamp was screwy. Lol anyway, i didn't see the couple but they were in the room right next to mine. I could literally hear them through the door. I thought at first that it was more than just a couple in the room but after listening several times i think it was just one couple. Like i said, i didn't see them. There is some conversation towards the end but nothing significant that needs to be censored or deleted. The guy was joking with the girl about being a "five star fuck". ;d lol throughout the recording, you might hear some "knocking" and creaking sounds. Sorry. That was me. I kept my hotel door propped open and i was peeking out every now and then to check on my recorder. Anyway, i wasn't able to get a recording this year but i was able to find this one (that i thought was lost) from last year, so enjoy! :d.

I believe this to be a weasel, but it could have been a river otter, asthe only part of the animal i saw was the snout down a dark hole. Theanimal was amidst the riprap at the end of our garden, and beingtormented by two neighbourhood dogs. I shooed the dogs away, but theanimal continued to shriek for some time. I have this in wav format if anyone requires it, but i'm sending the mp3 because the original is 26mb long and i'm on dialup. ===fyi - i saw an animal swimming in the river a few days later, and am 98. 5% certain it was a river otter. =====2007-09-07ok. My biologist wife and i have come to the conclusion that it's an american mink (mustela vison). Poor little guy.

This is almost the same kick drum i´ve uploaded previously, but this has more compression and overtones in the sub bass, along with an interesting technique i´ve been doing, lemme explain. . . I put the original sample twice in my daw (fl studio if you ask),leave the first sound like it is and the second sample is being equalized in a way that only the sub bass is being showed, so i added to that the saturation plugin ivgi2 from klangheim industries and slammed it with the plugin ott by xfer records about 9 times. Equalized the sound again to cut the sub bass and leave the raw high end sound you hear, finally added an izotope ozone imager to make it wider.

I recorded this from a balcony (5th floor) in the middle of a summer day (end of july), using a mid/side set (mkh30 + c480 b-uls/ck62-df omni) into sound devices mixpre3. Not any processing has been added, except a plain m/s to x/y stereo conversion and low-cut filter (30hz). This is a generally quiet atmo, sometimes light wind comes in, some seagulls and other birds are there at times, some construction work happens etc. The traffic noise is present, but in the distant way. Feel free to use it in any of your productions. Not for resale.

The sound is coming from the fans of a server. By pulling out one of the fans, all other fans turn up to 100%. The microphone is located above the air duct exactly in the middle of the case and thus between two fan fronts. The soundfile starts with the fans on standard speed. After a few seconds the fans turn up to 100%. I left them there for a few seconds and then quietly plugged the removed fan back in. This fan now also switches to 100% - this is the single, delayed "speed up" that can be heard from second 35. About 10 seconds later, all fans return to normal speed. Unfortunately, a colleague came in at that time and ended up talking into the recording. Due to lack of time, i was unfortunately unable to repeat the audio that day, but will certainly do another re-recording in the future. Feel free to use the sound; no attribution required. Feel free to write me in the comments what you used the sound for. Equipment:røde lavalier microphonesound devices mixpre-3 ii. File:wavmono96 khz32-bit float.

(recorder: zoomh4npro 2018)(microphones: binaural roland cs-10em in-ear monitors). As these are recorded using binaural in-ear mics, i purposefully don't turn my head to keep the sound clean and coming from the same direction. Wow, this is a long one. . . But a good one. Let me set the scene for this audio because i am a nerd. . . Burbank, california. A large apartment/condominium complex with an open courtyard and a swimming pool and hot tub. Now, for some reason in la, nobody ever seems to actually use pools or hot tubs anymore so it's not hard to get clean audio. So, from beginning to end you will basically hear me turn the automatic shutoff dial on the wall, walk to the hot tub, get in the hot tub, and sit in various positions for extended periods of time. I was alone for the entire experience (wife was at work) and nobody joined. It's very clean audio and safe for all production. Recorded on 11/20/2018 in burbank, ca. Enjoy,. Christopher c. Courter.

I just recorded this on my phone whilst i was chilling in the conservatory atont the back of my house. . . The heavens literlly opened for a very heavy shower of. . . You will hear the rain on the roof and i move the phone closer and further away from the roof so to get a good soundrange. . I also open the door and let the recording pick up the natural outside showering and rain gushing over the gutters hitting the patio and back step. . Also i splutter a couple of times but its background. . Oh and a whistle at the end. . . Any changes or requests please feel free to ask/get in touch. . !!enjoy the golf all /=].

The guest room i am staying in has a tile bathroom. Each time i take a shower, i hear this magnificent hum of the water heater clicking on and then turning off once the shower water is stopped. I was fortunate enough to hear it click on while i wasn't in the shower and captured about 30 seconds of it before it died. Infinite variation, impossible to replicate. At the end, as the water heater shuts down, it clicks down into the lowest ranges of the frequency spectrum; i didn't hear it until i listened to the recording but the couple of seconds of that are just as magical. Wish i would have left the recorder running!. Captured with a zoom h3-vr to ambix format at 96k24bit and bounced to stereo. Processing: 24db gain to all 4 clips, izotope spectral denoise to get rid of the air in the room and izotope ozone to enhance the bass signal a touch. Enjoy!.

This stereo recording was made on november 23, 2014 in grays harbor washington during a rare thunderstorm. The clip contains rain falling on a wooden deck and recurring peals of thunder both near and far. This original recording was made using a zoom h-6 handy recorder with zoom stereo xy microphone. The track was edited in audacity 2. 0. 6 to remove a few artifacts. Total run time for this wav file is: 8:29. This is my first upload. I am hearing impaired and new to field audio recording. I am fascinated by this art form and hearing sounds that i haven’t been able to hear in twenty years. I would greatly appreciate your feedback on the quality of my work and, if you choose to use this in a project, the end use you have in mind.

Zip twisting mechanism sound, then a drop glug sound. Also sound like a bottle glug. Use examples: you can use this in a number of ways if you edit it. 1. Parking meter. 2. Edit/cut the sound so that it sounds like you are using a drink vending machine. 3. Use the end glug sound as bottle being put down. Or copy and past the glug multiple times in a row to simulate someone heavily drinking from a bottle. 4. Glug sound can be used as something dropping in water. -[ recording info ]-.

9-note ending riff. 1 of 8 samples under 5 seconds from my acoustic guitar recording of a civil war fife and drum song named frog in the well, which i learned from an 1862 instructional manual. The instrument was a 1928 gibson l3. There are no effects. Key is (in order of best fit) d major, f# minor, e minor, g major, a blues. Time signature is 3/4, but these samples are mainly under a bar so can be used in a 4/4 song. You also use either of these licenses for your remix: creative commons attribution-sharealike, creative commons attribution-noncommercial. The home of this song on the web is soupgreens. Com/froginthewell. That has the full source song in mp3 format and short clips (40 seconds, 30 seconds, and 20 seconds) for use in video cues. There is also sheet music and guitar tab there.

A complete trip on métro (subway) line 9 of the paris subway system, from the alma-marceau station to the havre-caumartin station. Starts with descent into the métro station and ends climbing up the steps back out at the destination. One train is allowed to pass, at about the 1-minute mark, as we wait on the platform, and an announcement giving the times for the next trains can be heard. The ride on the following train begins at around the 2-minute mark. There are two loud sounds between about 9:10 and 9:20 and some loud low-frequency wind noise at around 10:40 (as we leave the métro station and return outside), so beware. Recording with zoom h4n, originally 96 khz/24 bits, uploaded as mp3 320 kbps because the wav was so big (almost 500 mb).

A long recording on board the "green car" of the jr tokkaido line from atami to shinagawa. A "green car" refers to the first class cars on some long distance local trains. The ride is smoother and the cars are generally much quieter. The cars are generally empty but, this was at the end of a 3 day weekend, so the car was actually quite active (i'll try to get a quiet one soon). You can hear the ticket attendant, the conductor's announcements, station arrivals and departures, passengers getting on and off the train and settling in and having conversations. At some point you can hear the guy behind me eating senbei (a crunchy japanese rice cracker) - that's a little annoying, but there might be some usable bits in there if you're good at editing backgrounds. But like i said, i'll try to get a less busy train next time. Recorded with 2 stereo mic pairs and unedited.

This is my recreation of the noise in the background of a video shot on a consumer grade minidv camcorder (a well used one). I haven't had a minidv camcorder on hand for a few years and nobody i knew would give me a recording of just tape motor noise so i went to create the noise myself. This sound is a combination of a very badly pressed dvd in my computer's drive mixed with a tone made in audacity (up one octave from the tone that the disc ended up creating), all mixed down and brought down in volume. I know it's not a prefect recreation, but i don't have a minidv camcorder on hand so this is about as good as i can get it. If anyone has access to an anechoic chamber, a fresh tape, and a well used consumer grade minidv camcorder, please get in touch with me. I'd like the real deal better than my recreation that i did in my spare time. Note on recreating the noise out of hdv camcorders. They have slightly different hardware and as such will create different bearing noise (most times, there's an extra whine on top of the familiar bearing whine heard from standard dv camcorders). I forget the exact frequency, but it's somewhere in the neighborhood of 840hz-860hz and it's a sort of sine wave, but a modest bit more jagged. You'll have to provide your own stock camcorder mic hiss as each camcorder is different (not for definite sure on sony camcorders, but canon camcorders have a pink-ish white noise in about that era).

Zoom h4n - onboard microphones. This recording was captured in the city of orange in orange county, california. This is located just below los angeles and less than a mile from disneyland in anaheim. This is an extremely clean recording of a sudden cloudburst that turned in to a torrential downpour on december 28, 2020. The peaks are all very close to 0db. I opened the sliding glass door to our balcony and placed my zoom h4n as close as possible to the rain without destroying the recorder. What resulted is an amazingly layered rain track. This is because rain can be heard striking multiple surfaces such as a tree, a metal table, the cement balcony, etc. . . There is not much thunder (that's rare in this area) but if you need a few dramatic thunder claps they can be found at the following times one the file is downloaded. Note: that the rain decreases in intensity near the end. 8:09 - 9:37 - 10:31 - 11:20. - christopher.

A third version of https://www. Freesound. Org/people/gis_sweden/sounds/352940/. Now i let the alm pip slope affect a filter. I play a little sequence made with cvlfo , clock divider, attenuverter, quantiziser. The way i usually do…. But the interesting thing is the cvad (?) voltage controllable envelope generator. But in the case of alm pip slope you just control attack and decay. Seems to be enough. As in the other versions of this sound i connect one lfo to attack and a second lfo to decay. But this time i connect the vcad to control the frequency of a filter. Interesting. I wish i had two more cvlfos… should open up for rhythmical usage. I use no vca or adsr. I have connected the vco straight to the vcf and the vcf to mixer. In the beginning i have the frequency pot at 2 a clock then i gradually move it clock wise and let the vcad take control. 1 minute in the pot is fully clock wise. The vco is playing a sawtooth wave. If you dl and inspect the wave you can see that in the beginning and the end it is a sawtooth wave, but in the middle part the filter affects the wave form.

. . Inside an intercity express (ice) between stuttgart and mannheim, sitting in an almost empty (three passengers) second-class broad-spaced compartment at around 9 pm. After a shaky first minute an even part follows for around 90 seconds. Interrupted by some road holes the steady sound continues, now with the frequency of the engine sound rising until the beginning of the fourth minute. Here the "main part" begins, starting with several moments of acceleration, deceleracion and breaking. From minute 5:15 to 7:35 the train reaches it's peak velocity, with only few bumps. After a short deceleration the train inceases velocity again, reaching a second peak, this time noticeably bumpier. Once in a while you can hear some element of the fitments rattling nervously along the track, depending on the constitution of the railways and the overall situation. During the last two minutes the train keeps on decelerating slowly and continuously until the end. Recorded in stereo with a portable stereo recorder (zoom); enhanced in audacity using a parallel dynamic eq (tdr nova), a compressor (vos density mkiii) and a binaural spacializer (auburn panagement).

Recorded in my dad's bedroom with lifecam hd3000 webcam. This is a much better recording than my previous oxygen concentrator file, as i hauled my desktop into the bedroom at the other end of the apartment where the machine now is, when i was home alone. The webcam is on the bed about 3 or 4 feet from the machineat the beginning of the file you hear me flip the big switch and the machine comes on with a long on beep and thumps. I edited it to start then. At 00:1. 8 what i suspect is the water pump comes on, though i may be wrong. That's when the gurgling starts though. The machine has a small reservoir for distilled water to moisten the airflow. A cup or two lasts several daysyou'll hear various hisses and thumps in a 15. 6 second cycle as it runs. At 03:03 i flip the big switch to shut the machine off, and it bubbles and gurgles away for the rest of the file, as water i assume slowly perculates back into the reservoir, the bubbling getting quieter and quieter until it doesn't even sound like bubbling anymore, until it finally ticks to a stop. At 03:16 you hear me step as i get my foot loose from the mic cord lol. At 04:13 the furnace shuts down as a car finishes going by outside in the bass register, faint traffic noises and the furnace being the only background noises you'll hear aside from my moving around a couple times, and a faint bluejay at the end. At about 07:00 you can barely hear the machine anymore, but i could hear a faint ticking with my own ears. At 07:04 the furnace comes back on. At 07:08 you'll hear a bluejay faintly calling outside and a car going by outside after, which finishes the file at 07:20. I edited out my walking to the computer to shut the recording down. From wikipediaoxygen concentrators typically use pressure swing adsorption technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurised oxygen is too dangerous or inconvenient, such as in homes or in portable clinics. Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants. Oxygen concentrators utilize a molecular sieve to adsorb gasses and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gasses to pass through. This leaves oxygen as the primary gas remaining. Psa technology is a reliable and economical technique for small to mid-scale oxygen generation, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes. [1]at high pressure, the porous zeolite adsorbs large quantities of nitrogen, due to its large surface area and chemical character. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb. An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir, and some valves and tubes. In the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time the pressure in the first cylinder rises from atmospheric to about 1. 5 times normal atmospheric pressure (typically 20 psi/138 kpa gauge, or 1. 36 atmospheres absolute) and the zeolite becomes saturated with nitrogen. As the first cylinder reaches near pure oxygen (there are small amounts of argon, co2, water vapour, radon and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen enriched gas flows to the pressure equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle, there is another valve position change so that the air from the compressor is directed to the 2nd cylinder. Pressure in the first cylinder drops as the enriched oxygen moves into the reservoir, allowing the nitrogen to be desorbed back into gas. Part way through the second half of the cycle there is another valve position change to vent the gas in the first cylinder back into the ambient atmosphere, keeping the concentration of oxygen in the pressure equalizing reservoir from falling below about 90%. The pressure in the hose delivering oxygen from the equalizing reservoir is kept steady by a pressure reducing valve. Older units cycled with a period of about 20 seconds, and supplied up to 5 litres per minute of 90+% oxygen. Since about 1999, units capable of supplying up to 10 lpm have been available.

In front of my desk in my room is a wood paneled wall with a cubbie. It's about a foot wide, 10 inches from top to bottom and maybe 7 inches deep. I'm just guessing. Around this cubbie is a border of wood. In the bottom right corner under the border i have jammed one end of an elastic string that used to have glitter on it. It's from a christmas box of chocolates my uncle sent me last year. I stand in front of this cubbie whose bottom is at chin height, (i'm only 5ft1in) so my arms are above my head as i pull this string across the cubbie up and to the left to the border on the top which acts as my only fret. The string is a few inches longer than the cubbie is wide, but when i pull it it gets longer so my hand is 3/4 along it's length as i pull back and forth across the border to tighten and loosen the string. No matter how hard i pull it never pops loose from it's mooring. This time the mic is sitting in the cubby so i get a much clearer and louder sound. When i stretch the string across the top it has a fairly long sustain, so i can play 4 notes on a single pluck.

A few cycles of my dad's home oxygen machine with a ticking battery operated clock in the background recorded in the early morning in the living room with lifecam hd3000 webcam at the end of about 16 feet of usb cable dragged out of my bedroom. He's about 6 feet away, i was with my back to the room with my camera pointed at my chest so he wouldn't think i was filming. It would seem this is the first and only oxygen machine on freesound. A full cycle seems to last from between 7 to 10 seconds.

Older units cycled with a period of about 20 seconds, and supplied up to 5 litres per minute of 90+% oxygen. Since about 1999, units capable of supplying up to 10 lpm have been available.

Calm ambient track. Winter woods / pinewood february 12. 41 pm (noon) in the netherlands near village giersbergen. Bram’s admin request-text and my answer in audio. Hello freesounders,it happens very infrequently that i post requests. However, i have an extraordinary sad reason to do so today. I don't want to go into detail in this public forum, but someone incredibly important and incredibly young in my life and my wife's just passed away. I am thus looking for an extra long recording of a peaceful "forrest ambience" to play during the good-bye ceremony. Something with some birds and perhaps some wind through the leaves,. . . . Currently the ceremony is planned for april 6th so i would need this before then. I know i can look through freesound, but i would like something specifically recorded with this in mind, something we will be able to listen to later as well, remembering this important and sad time in our life. . . Yours in grief,- bram & familywhat you hear;general-noise; soft wind in woods, sometime a bit increasing. A far kid at the edge of hamlet giersbergen. Far hum of the woods.

Nl/natuurgebieden/nationaal-park-loonse-en-drunense-duinen. In the loonse en drunense duinen you will find forest, heathland and especially a lot of sand. It is one of the largest shifting sand areas in western europe. The wind can blow undisturbed in many places, resulting in an ever-changing landscape. By purchasing it in 1921, it has been protected for 100 years and we can still enjoy this brabant sahara today. You can roam freely on the sand plain. So there is plenty of room to explore extensively. Marvel at the submerged trees, enjoy the chirping field crickets and quench your thirst at one of the many cafes or restaurants on the edge of this nature reserve. Walking, cycling or on horseback: it's all possible here. With the wind in your hair and the sand in your shoes. You may even come across the sheep herd. The sheep keep the heath short and eat away saplings. This is how they keep the area open. The loonse en drunense duinen still has 270 hectares of shifting sand. That sand creates rather extreme conditions: the soil is dry and nutrient-poor. The difference in temperature between day and night can be as much as 50 degrees celsius. This ensures a unique flora and fauna. The animals and plants have adapted or feel at home in drought, aridity and temperature fluctuations. Sand sedge and various lichens, for example. And the viviparous lizard, sandpit beetles and sand bees. All species that love sand. In the last ice age, the polar winds blew sand from the north to brabant, where it remained in thick packages. For a long time this sandy plain was covered with primeval forests. Until the fourteenth century the trees were felled by people. They used the wood as fuel. The bare plain was filled with heather, where the farmers grazed their cattle. This intensive grazing and the sod cutting of the soil depleted the soil. This gave the sand free play. For a long time, the sand was a major problem for the residents. Villages and fields threatened to disappear under it. Trees were planted to stop the advancing sand. You can still see the traces of this today: find the submerged trees that only peak above the sand hills with their crowns. Date/time: february 15th tuesday 2017, start 12. 44 pm.

We are writing the end of the 20th century _ _ _ cheer up !. After a nice concerto @ the charlatans, ghentduring the infamous ghentse fiestas ! ! ! ! !one of the guitarists of the band torturadodrives back home,. . . 72h after the concertthat is. . . He don't remember having slept. . . Ghentse fiestas are hardcore, he does rememberthe hamburger @ the vlasmarkt though. . . &he thought he heared 'vree wijs' like a thousand timesbut back then he couldn't decifre the real meaning of thosemumblings. . . So he always answered back to the girls, with 'i'm latino !' ( the usual reply). Hm,. . . Suddenly on the radio he hears musicwhich strangely seems familiar to himwhen the radio host describes the artisthe seems to be talking about the torturado boi ??!!!!##is he ??!!!!!#é"'((('à)§!(çà. Is this some kind of message from the future ???. The reference of glenn branca is there, but 2015 ??? never happened yet. . . Wooooooojoo !!!!. There is also this clear 'why nut' 2020 duyvisch nuts publicity reference !!!that he obviously doesn"t get yet, but an invisible force, makes him grab some nuts (not what you think), he bought just before entering the car ??!!! (you see!). Is this some kind of message from the future ???. No ! as the host continues the little descriptionhe makes a t e r r i b l e trabalengua or you knowknot explosion with the tongue & has to repeatthree times the sequence of the stroboscope. Wtf is going on here. . . The future seems to besending a very unflattering non elegant message to him _ _ _.

Created by divkid for use in the make noise soundhack morphagene. There are dry-only, fx-only, and mix versions of this reel in the pack. See it in action at https://youtu. Be/rk4ufmfcouc. Patch walkthrough. The patch starts with the qu-bit chance providing discrete random values (sample and hold) going into an instruo harmonaig. This takes the stepped random voltages and quantizing them to a given scale. I put in the notes c d eb f g ab bb which is a c natural minor scale, the relative minor of eb major (for anyone that's curious). However like most of my modular work i didn't actually tune the oscillators to anything specific. So treat the scale as a pattern of intervals not a set of specific notes. The quantized notes then form 4 voice chords giving us a root, third, fifth and seventh cv output that will be diatonic following the scale pattern, meaning the third will be major or minor, the seventh major, minor or dominant and the fifth natural or diminshed to suit the scale. With the 4 quantized outputs on the harmonaig these all go into the four oscillators on the synthesis technology e370 quad morphing vco. Each of the e370 oscillators are in the basic morph xy mode using the built in rom b set of wavetables. Wavetables are modulating by various mixes of the befaco rampage, mutable instruments tides, wmd multimode envelopes and music thing modular turing machine. The modulation sources are mixed and split with multiples and mixers. These modulating wavetables then go into a bubblesound vca4p where i'm using 4 mk1 intellijel dixie oscillators all un-synced and free running with sine wave lfos. Each lfo freely fades the voice in and out of the vca4p. As this is unsynced there's no regard to pitch changes linked to changes in amplitude and the swells. I find splitting the gate/rhythm from pitch regarding sequencing to be a freeing and interesting way to work that's not available on traditional instruments. This is just a simple application of that idea with the lfos fading freely unrelated to the other modulation or sequencing of pitch. The sound then goes from the vca4p mix out into a befaco mixer and praxis snake charmer which the output section of the larger case and i'm sending a 'pre' auxiliary out into my fx case. The dry sound first goes into the erica synths fusion delay / flanger vintage ensemble which is giving me short modulated delays giving vibrato like sounds and pushing the input level and overdrive gives us some warmth and grit that thickens up the sound and also fills in the gaps left by the free running lfos pulling quieter sounds and compressing in the on board tube. This then outputs to the feedback 1 bit multitap delay module which has it's delay chip pushed to longer times for some added crackle and noise. I'm using the two delay taps for a shorter and longer delay with little feedback to mix the dry sound for a generally noisier and smeared version of the input. This then goes into the xaoc devices kamieniec with it's on board lfo as slow as possibly for a mildly resonant phase shifting. This goes into mutable instruments clouds set to sew random grains slowly and randomly which are pitch shifted up 2 octaves to fill out some high end flourishes against the closed chord voicings at the core of the patch. Finally this goes into a long lush reverb from the halls of valhalla card in the tiptop audio z-dsp. The stereo fx chain and the mono dry signal are mixed in the befaco hexmix and recorded as a mixed stereo file. I'd consider this to be the main 'reel'. However i split the dry signal and the fx only wet stereo signal and recorded those at the same time so you can choose which reel to use and experiment with dry/wet or blended sounds from this patch.
