FA-10805 / PCM sample encoding / Member archive
Pcm16 saturation before encoding · case 05
Overflow wraps a large positive sample into a negative amplitude.
Case contract
Saturate arbitrary integer intermediate amplitudes to the asymmetric signed 16-bit PCM range.
Why this case matters
A pure Python local audio pipeline stage with explicit sample formats and frame conventions; no real-time device or signal-spectrum claims.
One recorded failure
