FA-49354 / PCM sample encoding / Member archive
Pcm channel predictor: reset bank · case 04
A channel reset discards transmitted nonzero seeds.
Case contract
Encode frame-major PCM residuals with independent per-channel amplitude predictors and frame-index resets; preserve residual frame shape.
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 | [[[1, 2], [3, 8], [4, 1]], [7, 9]] | [[[1, 2], [2, 6], [4, 1]], [7, 9]] | Failed |
