Audio asset generator live
Placeholder tracks for test data, written on your disk: pick a duration, a format and the rest, then Generate.
Generate writes the tracks into audio-assets/ at the root of the repository, on your disk: the folder is committed, the files never are (.gitignore). Each track is random noise under a slow modulation plus a frequency sweep, different on every file, held just below full scale so nothing clips.
The form keeps the rules a distribution platform applies: 16-bit is disc rate only (44100 Hz), 24 and 32-bit take 48, 96 or 192 kHz, FLAC has no 32-bit encoding, and one request weighs 90 MB at most before encoding. â–¶ plays a track here, Download saves it, Delete removes it from the folder.
