Pcm16 to float asymmetric range · case 05
Normalization by positive maximum pushes negative full scale below -1.
Case contract
Convert signed16 sample integers to normalized floats by dividing by32768; maximum positive is below one.
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.
