FA-49685 / PCM sample encoding / Member archive

Pcm feedback saturation: clamp order · case 05

Input-domain amplitude is clamped directly as output code.

Member previewVariant 5 · 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 2	`[[[-3, true], [-1, true], [-1, true]], 0]`	`[[[-3, true], [0, false], [-1, false]], 0]`	Failed
