All bundled clips were trimmed where specified, downmixed to mono, resampled to 22050 Hz, adjusted to a 0.48 PCM peak, and faded for 10 ms at boundaries by the PEKO project. These edits do not imply endorsement by the original authors. The car engine derivative is distributed under CC BY 3.0. Other entries use their listed public-domain/CC0 terms. Per-clip notices and source/derivative hashes are in Content/Audio/Licenses and natural-audio-manifest.json.

The remaining stock keys use locally synthesized playful cues; they are not natural recordings. Child recordings remain local and are never bundled with these assets.
