FA-10907 / Audio channel mixing / Member archive
Gain ramp reaches final frame · case 02
Dividing by sample count never reaches the requested final gain.
Case contract
Apply a linear gain ramp including start on the first and end on the last of two or more samples; a singleton uses end gain.
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
