Excellent if lo-fi recording of three voices, two male and one female singing and building one note at a time a major chord triad, saying, "hello," thrice. I use it as a ring tone. Recorded with an ipod and griffin italk mic.

Here is a gas meter on a restaurant. I managed to get a chunk without much background noise here but i do change the mic position part way through the recording. . You'll notice it gets darker, then change it back. There's enough of each to get a good loop going as i have in the past. Recorded with a zoom h4.

My shepard tone done for my submission to disquiet junto project 0508. Raw without reverb. Not perfect. Works fine if you listen with laptop speakers. . .

Bach's "overture (suite) no. 2 in b minor bwv 1067: vii. Badinerie" converted into an 8-bit, chip-tune ringtone. It makes a perfect loop, so it is great for call ring-tone.

Old water cooler filter.

Yamaha tx81z initialized with mild adjustments, run through a korg ea-1. Mixed with a behringer, with fx sends going to a chorus pedal and a distortion pedal. Sampled with the mpc. Sounds similar to dirty guitar or an electric violin. 44. 1k, 16-bit.

Dave smith's mopho analog synthesizer's sawtooth wave sampled with an mpc through a behringer mixer. 44. 1k 16-bit.

Here is a sound that i produced in audacity by generating a tone and making the frequency very low. It sounds rather like a humming of a machine or electrical appliance! good for looping and such. Enjoy !.

A sound made for a project a few years back to sound like the whirring sound of a wind turbine.

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.

A wet finger rubbing on the outside edge of a crystal wine glass.

Crackle and popping from an ego one vapor cigarette device.

My heartbeat, recording with low eqing and a shure sm58. There's some moving of a microphone and a little bit of breathing. Towards the end i take a sample of my computer.

Interference is a interesting phenomenon. I blow a bass tone and add my own voice, first i adjust my voice to same wavelength as the instrument, then i change my voice linearily, and you can follow how you get a 3rd tone, which is either a+b or a-b.

These sci-fi synth sweeps were created by manipulating white noise with filter sweeps and other effects and then using noise reduction to remove the underlying white noise. You would need to pick through them and cut them up, but they can be useful for sound designing light graphic elements that move around and animate on and off.

Poorly tuned am station with several signals battling to come through at the 1600 khz setting.

Low pitch static which reminds me of 1950s sci-fi television. Created by filtering a static wave from an analog radio then slowing the pitch and adding a mechanization effect.

A short sound sample of keys being handled causing it to rustle.

Abstract, ascending "tone"- one oscillator frequency modulated by a sample and hold module- done using synfactory/studiofactory software.

Recording of an empty radio frequency.

Nighttime radio static at the am radio band setting 1400.

The jumble of competing distant signals at night at 1290 on the am radio dial.

Low frequency waveform.

Playing around with the excellent tuner at http://websdr. Ewi. Utwente. Nl:8901/. The website even has a recording button! this version is the same as "shortwave-sweep-and-beeps. Wav" except here i have limited it with a threshold of 10db, which decreases dynamic range but also makes it louder overall.

Pounding the back wall of a uhaul truck cab from the inside with my fist. Sounds great when you add reverb. Recorded with a tascam dr-40.

This kind of noise generates linearly interpolated random values at a certain frequency. In this example the frequency is 100hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

Something i accidentally got while messing around with voxal voice changer by nch software. It was a background noise of my mom closing a door, and i decided to put it in reverse and i couldn't help but notice that it sounded like a low "whoosh" transition. So i opened it in wavepad and added echo + reverb and voila.
