Pcm feedback saturation: clamp order · case 04
Input-domain amplitude is clamped directly as output code.
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 fixtureThis 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 |
