Free to use without restricition. No attribution required. 50 seconds of ghostly wails over a dark sub bass drone with wide stereo reverb. Produced by using two old school analog synths, a cs-80 and a dx7. All chorus, phaser and reverb settings were manipulated within the synths. An external hi-pass eq plugin was added in order to cut off the subs at 30hz. These old analog synths produce frequencies way below the tolerance of your monitors; thus the need for a bass cutoff, not to mention to also prevent involuntary bowel leakage xd.

Results from running randomly-generated neural networks (all weights in neuron connections start random and then slowly drift when generating). Although sample rates used are 44. 1 and 48 khz, sounds pretty lo-fi. The reason could be input compression needed for network to actually work. Each sound channel is an output from two separate neurons in the network. Each sample in this pack is generated by a separate network, as they wasn’t saved anywhere after they produce a thing. Global parameters (output compression, neuron count, drift rate etc. ) aren’t the same from sample to sample, too.

Travel to the depths of parallel worlds to bring you these 100 sounds never heard before. . . They will hear sounds of the flight of strange birds if they can be called that, of strangely shaped beings that emitted sounds i do not know where, of echoes coming from, who knows one. The ship that i take with me is the sirius quasimodo works station, the fuel to be able to move the ship and transport me is biotek the audacity travel recording log enjoy it; =). Ps: i have to give up the pills they produce a weird effect on me jajajajaja.

This is a sawtooth waveform suitable for easily tuning guitar by ear, comprised of 20 seconds each of e-a-d-g-b-e in sequence. Adjust guitar volume to same volume as the tone, ideally through the same audio output. Tune the string close to the tone, then listen for the subtle beat-frequency indicating not-quite-perfect tune. When the beat frequency goes away, your guitar string is in perfect tune. Also useful for adjustable bridges. The open string and its 12th fret octave will both produce no beat-frequency when the bridge is adjusted properly.

A recording of a shower door, i used this sound through izotope iris 2 to produce a low, slow bassy kick sound, for a pretty ambient piece i did. I don't know why i became fascinated with the shower door. Bathroom time can be surprisingly pensive, so perhaps the sound of the door shunting shut became associated with that introspective space for me. Yes, i am aware that this the second bathroom sound i have shared. This may take on a certain significance given the fact that i have only shared a handful of recordings, but i encourage you not to read too deeply in to this fact.

A low frequency hum that will work on pc speakers (at least it does on my pc). . - i made this sound because i needed a deep hum for a composition, but as it turned out my pc speakers cut off low frequencies. A quick googling taught me that this is common for many pc's, but also that there might be ways around it in terms of designing waves that the speakers can produce. And so, after playing around with audacity abit, i came up with this low frequency hum that works well for my purpose at least. - i hope it might help others with similar issues.

This sound is produced by a powerful computation machine at cbc (upf) for the brain cognition experiments. As researchers of the center for brain and cognition, we work to advance our understanding of how experience influences the emergence of structure and function through computational and experimental investigation. We are also interested in understanding how mechanisms regulating brain development interact with the effects of experience to produce the structural and functional characteristics of the brain. These lines of research clarify how specific biological mechanisms routinely support the emergence of cognitive functions, leading to insights into why experience is so important for normal brain development.

This is a percussion beats made at tempo 124. It spans 8 bars and is ready to be looped in your daw. This is a sound i've found in my old foxdot projects, it has a really cool "ocean" or "wave" noise-like sound that repeats at the right then left of stereo, in the end of each 4-bar segement. It layers multiple kicks and snares, with one of the sounds being stretched, that produce this "wave" sound. It can be evaluated in foxdot with the following code to replicate this result. D1 >> play(p[" [--]o h: -"]. Layer("mirror"),dur=pdur(5,8), rate=expvar([0. 09,2],8),sample=2, pan=sinvar([-1,1],16),amplify=0. 5).

A small, mechanical music box plays, slows down and stops. Synthesized sound with stereo light reverb effect. Duration 0'52". Three turns of a wooden boxed clockwork mechanical key followed by a bright, nonsensical music box tune. As the tune plays, the tempo slows down - gradually at first but becoming profoundly slower towards the end. Tune ends on a melancholic note mid phrase. Could be used as a standalone effect, or perhaps metaphorically as a cipher for the aging process and cessation of life. The clockwork key effect is a rapidly repeating single mechanical clock tick filtered to sound box-like. The sound of the music box tines was created with ni fm8 using four sinewave oscillators, one of which feeds back on itself to produce a hint of metallic ringing.

The story begins by a music that i found. A open door, heels, then silence, a chair, computer sounds with mouse, retake of music and close of the door. , who is the ending of music too. To produce that, i choose audacity; i take recorded moments of life. For the technique, i choose a fade in and fade out for the music and the recorded sounds fit well together. For the moments of silence, when the work begins, i only let the recorded sound talk without music. I choose to work with two mono audio tracks: on for the music and the other for the daily sounds.

Ambient sound akin to the bridge of a starship. Muted background hum with an overtone of air conditioning ducts. Pseudo-random high pitched blips occupy the soundstage. Could be used as an ambient sound loop for hi-tech / science fiction interiors such as a laboratory, a control room, or the bridge of a spacecraft. Created with two instances of flstudio 3x osc. One kicking out a pair of sinewaves plus noise for the background susurus (hum) and ventilation sound. Second 3x osc is set to produce two interfereing square waves for the blips, squeaks and buzzes. The background was notch filtered and bandpassed to mellow out the humming sound and reduce hiss. The blips were processed with flstudio equo, stereo enhance, fruity delay2 and fl pan-o-matic vst. Each blip was pasted by hand in a seemingly random but not too unpleasant pattern.

English. 1. With both hands i grabbed the rain stick vertically. 2. Lift it about 4 or 5 cm from the plastic mat on the floor3. I moved it up and then down until it hit a mat. The movement was fast, which causes the internal seeds to rise and fall, hit each other, between the walls of the stick and bounce when hit on the mat. The sound was captured with a condenser microphone. It was recorded with ardour 5. Español. 1. Con ambas manos agarré verticalmente el palo de lluvia. 2. Lo levánte unos 4 ó 5 cm del tapéte de plástico que se encuentra en el suelo3. Lo moví hacia arriba y en seguida hacia abajo hasta golpear un tapete. El movimiento fue rápido lo que produce que las semillas internas suban y bajen, golpearse entré si, entre las paredes del palo y rebotar cuando se golpea en el tapete. El sonido se captó con un micrófono de condesador. Se grabó con ardour 5.

I built it because i could. It is fitted with gliding linear slide carriage bearings, has a counterbalanced offset crank with needle bearings, a jackshaft to drive it from a variable-speed dc motor, and even a variable stroke length (which was tricky). Above all it has something i haven't seen in any of the machines one can buy, a bendable, collapsible coupling that would prevent injury to whomever is on the receiving end of the stroke. Clearly it will never be placed into production as it would cost too much to sell at a typical consumer price level. May all be for nothing because i can't get anyone to let me try it out, and i'm only accepting female applicants from among people i know. It's my machine. Sue me. This file is only 2. 6 seconds in length. If you use audacity to repeat it as i did, it will mesh perfectly together to give you any length audio file you want. I did that to produce "v2-reciprocating machine. Wav. ".

This replica of my tinnitus was created using the free program called audacity. Http://audacityteam. Org/i had to generate 3 different 'tones' and combine them before i felt the high-ish noise was close to what i hear. I then had to search freesound for something that i only hear beneath the high pitch noise when my house is very quiet, which is something like the sound of strong wind outside a closed window or a power station a mile away. It took me a few hours, and even then i had to manipulate the sound considerably. Thanks to felix. Blume forhttp://freesound. Org/people/felix. Blume/sounds/167684/#commentsthis natural wind sound file was equalized and leveled several times, then the sound level was reduced to blend with the high pitch. But it still wasn't right. So, not being an expert with audacity, i just went down the list of 'effects', trying each one, until i found "paulstretch", which somehow increases the time length of your sound file, without stretching as in 'elastic', which would deepen the existing tones, and apparently, without copying and pasting. The sound does change somewhat, becoming just slightly ragged, but it's a very interesting effect for this application and actually got used on both elements to produce the final sound. . I hope no one enjoys this sound and can't imagine that anyone will. It makes me feel slightly sick. . Info edited 28 oct 2021: with my tinnitus at it's current level, i will never, now, be able to reproduce it again, primarily because i can't hear any sounds i create in a detailed way. And secondly, because hearing this version of the sound these days is just too uncomfortable. 🥲.

We develop iphone app that perform musical analysis on recorded audio from the iphone. Our app implementation make use of the audio queue service to receive raw audio buffers from the audio queue callback. In the first version of our app we had the problem of too much clipping on the recording which degrade the accuracy of our analysis. We also suspected that the noise canceling algorithm in iphone 5 produce distorted sound, which is not much noticeable by human ear but distorted enough to affect our sensitive algorithm. We found that the solution to our problem is to set the audio session mode to kaudiosessionmode_measurement. This session mode is supposed to give maximum freedom for us to control the microphone input, which include turning off the automatic gain control and probably noise canceling as well. The solution works very well except that it introduce a strange waveform pattern in the beginning of all recordings in iphone 5. It is very hard to explain the waveform we get, so i made two recordings at freesound so that you can see it visually. The first recording is made in an almost quite environment, and you can see the weird spike in the beginning of the recording. The second recording (this recording) is made with constant background noise, and you can see that the actual sound wave is offset from the strange curve and gradually increase to its original volume. This waveform only happens on iphone 5 devices that we tested, and there is no problem at all for iphone 4s and older generations. We have tried various settings and the glitch is still unavoidable as long as we set the audio session mode to kaudiosessionmode_measurement. We also find similar glitch in one of our iphone 5 devices, in which the glitch happens even if we try to set just the input gain level without changing the session mode. We are not sure if this is a hardware-related bug in iphone 5, or if it is fixable software glitch in the future version of ios. For the moment we are looking for workaround that can avoid this glitch while automatic gain control and noise canceling are disabled.
