FA-49667 / PCM sample encoding / Member archive

Pcm feedback saturation: clipping detection · case 02

Representable endpoint codes are incorrectly flagged as clipping.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Bounded PCM error-feedback precision reduction with overload detection and explicit anti-windup reset only when output code saturation changes quantized value.

Why this case matters

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

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
oracle 3	`[[[3, true], [-3, true]], 0]`	`[[[3, false], [-3, false]], 0]`	Failed
