Saturalabs — original synthetic whoosh effects

The three WAV files in this folder are dedicated to the public domain under CC0 1.0:
https://creativecommons.org/publicdomain/zero/1.0/
This applies only to soft-whoosh.wav, quick-swoosh.wav, and low-whoosh.wav
in this folder. It does not license other Saturalabs media or third-party assets.

Each file is generated from seeded synthetic noise, a moving pair of one-pole
filters and a smooth amplitude envelope. No recording, generative AI output or
third-party sound is used. Files are mono, 48 kHz, 16-bit PCM WAV; each has a
sample peak near -6.02 dBFS and starts and ends at zero.

FFprobe is needed for the independent format checks. measurements.json contains
hashes and format fields. These checks are not a listening-quality benchmark.
