FA-49937 / PCM sample encoding / Member archive
Pcm calibrated nearest code: sample target · case 02
Every sample is encoded using the first sample target.
Case contract
Encode PCM amplitudes to nearest entries of an explicit possibly repeated calibration table, with a declared lowest/highest code-index tie policy.
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 1 | [0, 0, 0, 0, 0] | [0, 1, 1, 1, 2] | Failed |
