A sequence i made with csound. The goal was to make a hi-hat. There is extreme panning in the sequence and different central frequencies for each of these drum-like sounds.

A sci-fi sound effect suggestive of a passing spacecraft. Pans from l to r with doppler shift of frequency.

Random series of short high frequency sounds generated by arp odyssey. An accidental "r2 detour".

Waterfalls in italy. Recorded with tascam dr - 07x. Slightly eqed on the high frequencies to make it sound more cleaner.

Static on the radio as a result of tuning a few channels down on an existing radio station. A voice is heard but their words are undecipherable.

Recorded with original zoom h2, with high frequency boost.

Piano sound produced with fl studio 10 for the aspma course peer assesment 7 (part 2). Original sound from http://freesound. Org/people/hmartelb/sounds/328547/. This sound is the stochastic component of the hps model analysis using sms-tools. The parameters used in the analysis were:. Window-type = hamming;window-size = 3001;fft-size = 4096;magnitude-threshold = -120;minimum-duration-of-harmonic-tracks = 0. 1;maximum-number-of-harmonics = 200;minimum-fundamental-frequency = 80;maximum-fundamental-frequency = 280;maximum-error-in-f0-detection-algorithm = 5;max-frequency-deviation-in-harmonic-tracks = 0. 01;stochastic approximation-factor = 0. 05;.

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.

Rendered in reaper @48khz 32-bit fp with markers for all you morphagene fans out there. Enjoy rolling in the rumble!.

Sound / noise from the electromagnetic frequencies of a macbook computer while streaming music on youtube. There seems to be a lot of radiation and interference from the device. Recorded with a micbooster electromagnetic pick-up into a zoom h6.

Semi tuned tom tom sounds. Frequency based on pitchshifting. "a".

Synthesized sawtooth sound with increasing pitch. An initial click and noise are added. The sound is low-pass filtered using a cutoff frequency that increase during the sound.

This sound was created with layering and frequency processing. Bpm 110key g# min.

A sine wave pushed through some outboard to trade in some fundamental frequency amplitude for higher harmonics - hence the name.

Recording of a kitchen sink filling up, hydrophone in different positions: changing frequencies and texture. Mono, hydrophone (jrf).

Experimenting with reverb and frequency on my "meaty gunshot. Wav" sfx resulted in this; hopefully this conveys the audible sense that the gunshot is being fired underwater. Created and edited with audacity.

The parameters used for the analysis were:. - window: blackman- window size: 2001- fft size: 2048- magnitude threshold: -100- minimum duration of sinusoidal tracks: 0. 05- maximum number of harmonics: 100- minimum fundamental frequency: 150- maximum fundamental frequency: 250- maximum error in f0 detection algorithm: 5- max frequency deviation in harmonic tracks: 0. 05stochastic approximation factor: 1.

A sound stimuli to demonstrate combination tone from speakers. You should hear additional frequency of 500 hz. The sound itself is summation of1000 hz and 1500 hz.

Part of a shortwave radio teletype recording, made with a dx394 high frequency receiver. The signal is civilian, but could be used as a military sound effect.

User name fmagrao's sound 80761__fmagrao__siren was stretched, put in a sampler and played as described but of varying duration and it would appear that there is an optimum frequency range for these sirens. I will create a lower frequency version in due course and a foghorn/siren hybrid. The sound features on the following track along with other uncredited sounds downloaded from this site and i am genuinely grateful for all those contributions. Https://soundcloud. Com/klaxonite/klaxonite-3-190415.

Made from a tom drum i created with xfer serum in reaper. Rendered the instrument as audio, then, sampled a small section of the tom and looped it infinitely to create a static frequency. Then i added the reapitch vst and created a smooth automation curve down to -24 semitones. Lastly, i added a short fade in and long fade out.

This is the sound of brownyan noise, made with audacity program. Stereo of this noise created with amplitude at the default value, also with fade in and out effects added for the good results. Using headphones is the best way to hear low frequencies of this noise. Also this sound can be use for tinnitus problems or masking unwanted noises. Also, it's very effective for relaxation, sleep or meditation. Enjoy it, and download this is recommended due to the bad quality preview.

Created using lmms and the zynaddsubfx plugin with loads of automation on the filters.

This sound was made in audacity using three rising sine waves at different frequencies. It can be looped to make an alarm.

Amplification at -28,1 to diminish sound. The sound has an effect which turn; a rounded up effect. Retro flanger has an average stall (8,02 ms) and flange frequency (1,58 hz).

A middle-frequency note that sounds like a swiss alpenhorn or person blowing into a conch shell. Made by blowing into a short section of pvc pipe.

Grabación que representa el sonido de algun ser externo. Disonante como si fuera un rastrillar sobre un tablero.

An irregular rattling noise from a 70 years old electromechanical electricity meter along with a constant mid-frequency hum.

Dedicated to friend jan alois :-) who needed to mark frequency shift of his transceiver and keying quality. I forgot the band - probably 80 m.

Sound of a high speed train leaving lleida station. A kind of glissando or frequency sweep is produced when the train increases his speed.

It's a recording of a modern portable cash register printing a daily report. Then the paper tape is ripped of. There are funny frequency effects caused by the paper tape getting longer and resonating different frequencies. The sound have not beet piped through any processing. Recorded with a hand-held zoom h2's rear mics. Originally 96khz/24-bit wav. Edited and converted to flac using audacity.

Stochastic synthesis output sound obtained by analysis and synthesis of sound speech-female. Wav (http://freesound.

Buzzy patch of static from the am band of the radio dial. Slight flipping of the dial through the area adjusts the sound.

Appended series of different recordings of neighbours slamming their doors. Noise reduction and reverb applied.

This sound is 50 ms, 2000 hz pure tone with double linear fadeout through it's whole length. Sampling rate of 8 khz is already an overkill (nyquist frequency is at 4 khz, while all energy of this sound is present in narrow 2 khz frequency range). Created with audacity for use with ardour 3, a free and opensource daw for linux and mac (http://ardour. Org).

A sounds made with a microwave. High pitched sound looped 15 times. Enjoy!.

Buzzy patch of static from the am radio dial slowed and with a filter and some digital reverb.

This sound was made in audacity using three different sine wave frequencies set to 200% speed. It is designed to loop seamlessly.
