This is an editied version of acclivity's sound file, "30832_acclivity_summereveninginmygarden". His original file contains a barking dog, which depending on your usage, can deter from the intent of your project. Since acclivity's recording has excellent signal to noise ratio, and has captured some beautiful birdsong, i thought other people might be able to use this edited file with all the dog barking taken out.

A signal sound of the pedestrian traffic light in the center of auckland city, new zealand. A sound archetype that you can listen in most of the main crossings in auckland. Background noise: traffic, human voices, girl playing accordion. Recorded by a iphone 4 internal mic. Recorded on february 02nd, 2015 in the light crossing of queen st and wyndham st, auckland cbd, new zealand. Recorded at 14:59pm.

This sound was recorded halfway up to the castle santa barbara in the city of alicante. Signal that carries a connotation of alert. His tone and timbre are characteristic of this element. "possessed by almost all modern cities and whose use is reserved for that fateful day when the sound will be followed by the disaster. " (schafer, 2013). Recorded by a zoom h5 recorderrecorded in 48khz 24bit wave. .

This is an alert signal from a real fire station. I tried to make a sound how they wanted it, and what i believe what was needed. Few things like 1) start softly to ease it when waking up in the night 2) some pauses for better recognition of speech or other signals heard same time 3) good cut trough background noise or whatever, stressless but good cut trough 3) limited length before announcement.

Electronic descending tones, could be used for a game over or lost a life for a game, or perhaps for a digital signal for another kind of event in a game?. I make other sfx and short musical compositions for games/apps, i release all sounds here under creative commons no restrictions to do as you wish with, so check out my other sounds.

This is one of the many sounds that reactable from mtg (upf) can do. Mtg is a research group specialized in audio signal processing, music information retrieval, music interfaces, and computational musicology.

Murchunga (nepali: मुर्चुङ्गा) is one of the ancient musical instrument as jaw harp. This collection is a sample sound from one-particular instrument that comes pre-tuned to a scale when crafted. And the device being too tiny to produce the sound signal, it was difficult to record the full length and frequencies. There could be other better sounds from a professional recorder. It just gives an idea of how it hears.

This is a fragment from the aria ah mes amis at a lower pitch and badly performed. Iintend to use it for a coursera homework (audio signal processing for music applications). The intention is to transpose it and simulate a morfing like a falseto to the true key where the tenor hits high c, which i obviously cannot hit, otherwise i wouldn't be taking coursera courses and uploading to freesound. . .

A recreation of a lavalier microphone pop. Useful for reality or documentary where an interviewee may rip off their mic or you simply want to create the illusion of that drama. Also useful to incorporate into a "signal lost" effect, etc. Processed with some limiting so it's tamed and ready to throw in a mix. Recorded with an mxl lsm-3 dynamic mic, no reason to abuse my real lav mics.

This is a field recording, done using a zoom h6 with attached stereo mic. The limiter (general type) was activated on the channel. This is the raw recording without any eq or dynamics added. A quick normalization gave a nice, rich signal that you might be able to use for any purpose. Apply a low pass filter to cut out the rain. Well, enjoy. :). More of this will be uploaded.

Rndstep generated sample and hold signal of the waveshaped neóni output passed into rings same cv used through dpo, some low pass filtering in qpas, much modulation using øchd, erbe-verb as reverb. Morphagene mix 50:50 1/2 speed, slide position modulated with øchd. Fed into x-pan. Morphagene ready, so get ready to enjoy for incidental stuff etc.

Japanese traffic in the summer: passing cars and tracks and some motorcycles, cicadas, recorded with iphone, nearby crossroad of the six-lane road and a large park in tokyo. First 40 seconds is crossing the six-lane road. From 54 seconds cars in the six lanes start to come toward me and pass by. At the end of the audio, the signal turns to red again. Pedestrians cannot cross this road.

A marimba note being struck while thrown in to the air. Can't remember the mic that was used but it was a condensor mic. This was recorded in my room so unfortunately the signal to ambient noise ratio isn't great. The sound can be used for free (though it would be great to hear about what you do with it). It may not be re-distributed as it is, or as part of a compiled sound library.

A simple recording of a metal drawer. Recorded with zoom h4n + sontronics stc-10 pencil condensors. This was recorded in my room so unfortunately the signal to ambient noise ratio isn't great, i think it's just passable though. The sound can be used for free (though it would be great to hear about what you do with it). It may not be re-distributed as it is, or as part of a compiled sound library.

Recording of an apple iwatch ver. 6 using a akg pro audio c411 pp high-performance miniature condenser mic. Recorded on mixpre10t. Using thin double back tape, i taped the back of the mic to the back of the watch. This watch has cell phone option. I think the intermittent burst of static is the cell phone in the watch ranging signal, similar to a full size cell phone pulsing when they range signals. If anyone knows, leave a message.

This helicopter sound design was created at fl studio, in the sytrus synthesizer. The sound consists of four layers. 1. Sine wave frequency of 44 hz. Simulates the low frequency noise of propeller blades. 2. White noise passed through the svf filter. Simulates the noise of propeller blades. 3. Saw wave. Simulates the sound of an engine. 4. The sine wave. Imitates a high-frequency whistle of the engine. Various modulations are applied to all waves through the envelopes of the synthesizer. Next, the signal on the mixer channel is processed by a multi-band exciter and equalizer. Then a signal was sent to two channels with delay processing. One of them imitates reflections. In the lower-middle frequency range. On the second in the upper-middle frequency range. As you approach the sound source, the volume parameters of the direct and reflected signals are automated, low pass filter, pan width and equalization of direct sound. The helicopter performs strange maneuvers, as if making constant circles during the approach to the listener. I did not seek to create the veracity of these maneuvers.

Processed version of:https://freesound. Org/people/toiletrolltube/sounds/422056/which is itself a processed version of:https://freesound. Org/people/gis_sweden/sounds/417382/. Signal chain was as follows:1) gate (otherwise the quiet parts would have a lot of digital sounding noise after processing)2) spectral processing (frequency reversing) applied using unfiltered audio's specops vst plugin. 3) reverb4) slight compression. Effects 1), 3) an 4) above were applied using ableton live's built in effects.

This is a transformation of the original recording https://freesound. Org/people/pinehadmz/sounds/369501/. For week 10 "musical piece" assignment for the audio signal processing for music applications online class. There are three layers, panned in stereo. Each syllable of each layer was randomly pitch shifted to a note in the minor scale using the harmonic plus stochastic model. Each harmonic track was thickened with extra harmonics during the synthesis process too to make it extra weird.

An edited version of my upload uke_single_notes. Wav. I shortened that recording to its last four notes, then included a fade out to eliminate most of the non-ukelele sound at the end. This recording has notes as follows: g4 g4 a4 d4. This sound was originally created for the coursera course "audio signal processing for music applications. " i recorded this sound myself with a zoom h2 microphone and a kala classical ukelele.

Violet aka purple noise power density increases 6 db per octave with increasing frequency over the frequency range. It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. I created this by looping http://en. Wikipedia. Org/wiki/file:purple_noise. Ogg. Which is copylefted, however i claim that they can't be protected based on http://en. Wikipedia.

Broadmoor hospital siren test. The broadmoor siren. Every monday morning at ten o'clock the deafening sound of an air-raid siren disturbs the peace over a large area of the leafy commuter belt that is berkshire, uk. The signal sounds the familiar alternating high-low note, followed by a constant all-clear note five minutes later. It's not a re-enactment of the blitz; it's a test of the escape alarm at the local mental hospital, broadmoor.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.

Formatted for use in the make noise morphagene. Seven chords from my fender rhodes, each on its own splice, centered around a bb-minor root. The rhodes was running through an mxr zw-44 for mild overdrive, and the signal was boosted with a focusrite scarlett dynamic octopre.

Sounds generated by assigning the "wave out" or "line out" signal of the soundcard to a track in fl, and turnin it up. This acts as a digital delay effect with infinite feedback and a very high cycle rate. Basically the noise (similar to pink noise) is produced by the soundcard and the resonance is produced by the low pass filter and the convolution reverb mapping of the waldassen cathedral.

This is a short fragment of one of the experiments done by the music and machine learning lab at mtg (upf). The aim is to develop an automatic violin teacher using ml techniques.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a low acoustic impedance. Humans will be able to identify tones as low as 12hz. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.

This jump scare sound was created by playing 2 dissonant chords on a single coil telecaster mic'd up w/ a vox ac 10 amp. The two guitar tracks are panned left and right- reverb and delay are added. Additionally, frequency enhancers were added between 4khz - 6khz which adds a higher tonal energy in the upper range of the guitar. Gain is added which can be heard as signal noise mostly at the end of the clip. Enjoy. Bainmack.

This is one of multiple samples i have recorded from short wave radio, and should, if i uploaded them properly be located in a pack of more radio samples. How the name is built up:sdr %yyyy-mm-dd%_%frequency% %description% (unfortunately i didn't get to put in the decimals of the frequency when i exported the samples t_t)i love you if you give me some credit, but it's not a must. Feel free to use it for whatever you'd like and by all means, link your work here so i can give it sum luuuuv.

This is a great recording from my digital police scanner of the atf and u. S. Marshal's doing a short, but detailed road surveillance here in houston. The atf starts out talking about a place to meet, then they follow the target suspects vehicle. Once they lose sight of the vehicle, they decide to let the marshal's signal device, planted on the vehicle, track it the rest of the way. This is a fine example of the new p25 digital (some encryption used) radio system that many federal and local law enforcement departments are starting to use. Enjoy!.

Interesting (but painful) sounds made with a zoom h2 (front mics, low gain) connected to a laptop via usb. The signal was piped to old creative sbs250 spekers with 16ms of latency (i'm using jack audio connection kit and linux). That's how my feedback loop came into existance. I turned up the volume and started to move the mics around, geting a lot of different sounds ranginf from simple tones to strange lfoish sounds. The sound touches 0db one times, but is rather undistorted (at least digitally). Recorded with audacity @ 48khz/16-bit and saved as flac.

I was playing around with my sampler fx today and decided to rig up my electric guitar. I use a fender american special stratocaster, hooked up to an akai s2000 sampler with on-board fx - distortion and guitar metal applied in real time, the signal then sent through to amplitube fx rack on my computer with vintage crunch setting. This is a strum of the lower e open. I recorded a number of stabs and thought this clip might come in useful.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a lot of harmonic distortion. Humans will be able to identify tones as low as 12hz. From 1000 hz the auditory system decreases. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.

Clattering about in the kitchen drawer to get spoons out. Getting a bowl out. Shaking a carton of soup up, ripping the top off and pouring it into a bowl. Tapping the carton to get the rest out and then throwing it into the pedal bin. Opening the microwave door, putting the bowl of soup in, tapping out the numbers and then turning the microwave on. Beeps at 1:50 to signal the end then open the door again. Natural kitchen ambience. Wav 24bit 44. 1khz.

This jump scare sound was created by playing 2 dissonant chords on a single coil telecaster mic'd up w/ a vox ac 10 amp. The two guitar tracks are panned left and right- reverb and delay are added. The delay tail you can hear oscillates between left and right speaker as it fades. Additionally, frequency enhancers were added between 4khz - 6khz which adds a higher tonal energy in the upper range of the guitar. Gain is added which can be heard as signal noise mostly at the end of the clip. Enjoy. Bainmack.

Electro-magnetic interference from the colorino talking color identifier and light probe when held near the internal ferrite antenna on the back right of a 13-year-old boombox near the bottom of the am broadcast band, from 530 to 580 khz. You first hear the device inactive being brought near the radio. This gives a low buzz of stacato clicks. At about 00:23 the light probe button is briefly pushed, you hear a quick boop of the light probe with low light level combined with the beginning of the white noise of the device active. If you put your ear near it after you use it, you will hear a slight hiss from the audio amplifier carrier idling for about a minute after last use. On the am radio this translates to white noise. At 00:26 there is a double click and a distorted voice says black. The voice is being picked up by the am radio. 10 seconds of white noise and i press the color button again and it says black. I put something else over the color sensor and it says a few more things. At 00:51 i hold down the light probe button and try to point it at the light above my desk while still holding it close enough to the radio to pick up the emi signal. You hear a warbling tone at 00:59 as the light reaching the sensor increases and decreases in brightness depending on how it's pointed. The signal fades in and out as the device is moved around. This has all happened at 530 khz. At 01:37 i step the radio up to 580 khz where you get a stronger signal. Wibw from topeka competes with the noise throughout the rest of the file. At 01:51 you hear the distorted error beep as i press the color button without anything but air and light in front of the color sensor. It must be pressed up against the thing you want the color of, or it gets in too much ambient light and errors out with a loud protesting beep.
