Channel gains independent · case 04
A single gain replaces separately configured channel volumes.
Case contract
Apply a corresponding scalar gain per channel to each equal-width frame; gains length equals frame width.
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
