Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Decode independent seeded differential PCM blocks; seed is the first presented sample and declared sample count includes it, excluding padded residuals.

Why this case matters

Offline PCM interchange uses these exact bounded packet and sample representation decisions.

One recorded failure
