4 Royalty-Free Audio Tracks for "Pulsing Throb"

A low bassy throb created using audacity. I initially used the 'risset drum' creator. Then randomly altered pitch and speed, increased the bass, then copied and pasted repeats.

Generated in audacity by applying the vocoder effect to a sine-wave tone from a spoken work, "yes", recording and then removing the voice component. A short sine-wave tone was then appended to the end of each pulse to create a futuristic heartbeat sound. File available in. Wav,. Mp3, and. Aiff formats.

A heart beating.

The beautiful sounds of office life. This is audible interference from a cheap ballast in a florescent light fixture--or several in close proximity. (it's probably violating fcc regulations with rf output too. ) this was recorded with an iphone builtin mic, then processed to isolate the sound. It's a beeping / humming at around 3,800 hz. Each beep lasts about 1 second, followed by a half-second of silence before the next beep. Toward the end of this recording, it shifts slightly upward in pitch, to around 4,000 hz. Some typing on a keyboard can be heard in the foreground. (it's an office, after all. ).
