This is a very common sound at mtg (upf), specially at the audio signal processing lab, where they work with world music and computation. Mtg is a research group specialised in audio signal processing, music information retrieval, music interfaces, and computational musicology. This sound tries to reflect the work that is being done there about world music and computation. Learn more at: https://www. Upf. Edu/web/mtg.

This was produced by tapping on a stethoscope which had an earbud pressed against a shure sm57 mic. Low pass filter applied, as well as compression and a gate. Chorus added. Used a recording cassette deck as a preamp going into an m-audio audiophile usb soundcard. Note: if you're having problems listening to this clip, the cutoff frequency of your speaker set may be too high(solution: new speakers). The signal strength exists almost entirely in the very low frequencies, so you may need a sub-woofer to hear it. Otherwise, try turning your speaker volume all the way up. Doing so may saturate the signal and at least allow you to hear the harmonics of the signal caused by the distortion. I don't recommend it, but you'll at least maybe be able to hear something.

No, i cant really describe what this is! but i use a ring modulator. Two audio signals goes in. I guess the side band frequencies goes out??? or?! anyway the original frequencies are also in the mix. So, two audio signal and the result from a diy ring mod. Have to learn more. . . Read below!!! in this sound you are listening to, the result, the ring modulation, carrier signal and modulator signal. After some research. . . I write this for myself. . . Correct me if i'm wrong!!!from youtube (audiocollage)ring modulation is the sum and the differences of the carrier and modulator signal. Feed the ring modulator with 261,626hz and 391,995hz and you get (261,626 + 391,995) 653,621hz and (391,995 - 261,626) 130,369hz. From wikipedia". . . Neither the carrier nor the incoming signal is prominent in the outputs, and ideally, not at all. "". . . In the basic case where two sine waves of frequencies f1 and f2 (f1 < f2) are multiplied, two new sine waves are created, with one at f1 + f2 and the other at f2 – f1. The two new waves are unlikely to be harmonically related and (in a well-designed ring modulator) the original signals are not present. It is this that gives the ring modulator its unique tones. ". Above is true when using pure sine waves! waves with no harmonics. I have a passive diy ring modulator. I guess it's not acting "perfect". . .

Playing around with the twente university radio signal receiver. . . Thought it was interesting and decided to upload it. . . Also uploading this so i can remember it for personal use. . .

A gibson sg with custom-59 pickups playing the open a string. Signal was captured using the bridge pickup exclusively. Length of sound capped at 10 secs and fade out effect added in audacity.

Track made for the final assignment of the coursera course audio signal processing for music applications. Sounds from freesound. Org, transformed using sms-tools and edited in audacity.

Last message in a series. This time lots of receivers around could download signal. Mathematics analysis could find two words from what seemed to contain advanced maps of some kind. The two words were : asteroid coming.

I played a staccato chord into a reverb unit with an infinite delay time. The signal from the reverb was sampled into an akai s612, looped and then resampled into the computer.

This is a remix of oceas 8th loop at 130bpm, the samples in this pack were made mostly by running the original loop through a custom plugin i made with synthedit. The general idea of the plugin is to seperate the incoming audio into 8 seperate channels using high-resonance bandpass filters, then run each of the 8 channels through its own special effect including reverb, delay, harmonic generation, ring modulation, modulation of the original signal by the harmonic generation signal out, and another reverb.

Piece of human whistling, of traditional christmas spanish song, "fum fum fum", with some vibrato. (to be used in a project of coursera course "audio signal processing for music applications", given by xavier serra, of universitat pempeu fabra of barcelona).

This is a very short phrase for a hindustani raag that i recorded for my audio signal processing class. The notes are far from perfect but they should be the equivalents of f3 f# g# a# f# f.

A simple but effective white noise sweep up created using a white noise signal, using automation to change a simple filter and colour to the sound to create a sweep effect.

Sounds like a 50's b-movie of a space ship flying. This is an example of digital signal processing since this was created from recordings of random household objects in a studio.

An ir panning delay that might might give your mix a little extra. An ir whith both delay and reverb. Created by recording the impulse response of a signal going through echo farm and revibe.

This is a fragment from the actual kandimpu gamaka sound by vignesh ishwar uploaded by gopala krishna koduri. This is used for asssigment 7 and 8 of theaudio signal processing for music applications course by professor xavier serra.

Sliding bassline in wet format, check my account for the dry signal. Fminor > g#major > d#major > d#majorfminor > g#major > d#major > cminor.

This is a multisample of my stylophone as i move up the notes then after reaching the top i sweep upwards on the notes. This is of moderate quality, is a dry signal, but it is probably badly out of tune.

This is a sound of marker writing in a blackboard at mtg (upf). Mtg is a research group specialised in audio signal processing, music information retrieval, music interfaces, and computational musicology. Learn more at: https://www. Upf. Edu/web/mtg.

Just one emergency vehicle's siren, going from soft to loud and then tapers off slowly with some talking in the background. Beeps at the beginning are a crosswalk signal.

Studio technologies - stereo simulator (generation ii). Https://studio-tech. Com/products/generation-ii-stereo-simulator/. The generation ii stereo simulator from studio technologies creates a convincing stereo imagefrom a mono audio source. The fully mono-compatible signal simulates space withoutreverberation by using random, non-recursive filter techniques. The mode switch (found on the hardware unit) controls the overall sound of the generation ii. In the music position, the full audio bandwidth of the input signal is simulated. This mode isappropriate for audio material with little or no voice-only content. In the music & voice position, the input signal is sent through a band-reject filter prior togetting sent to the simulator circuits. This creates stereo simulation over the low and highfrequency range, while limiting simulation in the voice band. This mode is appropriate for audiomaterial that contains voice-only content, such as a film track or television show. The stereo intensity control determines the amount of stereo simulation that is produced. Inthe fully counterclockwise position (ir files “0” – included for process comparison), no simulatedstereo is produced. The mono input signal is sent equally to the left and right outputs. As thecontrol is turned clockwise (ir files “1 – 6”), the amount of stereo simulation increases.
