A minute of pure silence
One full minute of digital silence: no noise, no room tone, just a perfectly blank stereo file you can drop anywhere in your timeline. Idealized studio silence, ready for all your tests and tricks.
To create a custom silent audio file, go to my Silence Generator.
Typical uses (based on users’ feedback):
> insert clean gaps between songs, jingles or podcast segments
> mute apps or devices that insist on playing a sound file (alarms, notification systems, in-car players, etc.)
> keep players, audio engines or Bluetooth links alive without any audible sound
> work around tools and platforms that require an audio track (force video export instead of GIF, pad the end of a file, calibrate meters, etc.)
It can also serve as a symbolic “minute of silence” in streams, events, radios or artistic projects. Free and royalty-free (CC0) for all your uses. UCS Category: TEST. Length: 01:00.
White Noise
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density (https://en.wikipedia.org/wiki/White_noise). A sound to use only wav, aiff or flac formats, because the other formats denature the interest of the sound. UCS Category: TEST. Length: 05:00.
Pink Noise
Pink noise or 1/ƒ noise (sometimes also called flicker noise) is a signal or process with a frequency spectrum such that the power spectral density (energy or power per Hz) is inversely proportional to the frequency: https://en.wikipedia.org/wiki/Pink_noise. UCS Category: TEST. Length: 00:19.
Zapping
0.4 second white noise that is placed between two images when zapping. UCS Category: TEST. Length: 00:01.
