FA-49485 / PCM sample encoding / Member archive
Riff pcm data spans: data only · case 05
Unknown chunks after format are presented as PCM sample spans.
Case contract
Locate PCM spans in a bounded RIFF-like list of chunk descriptors with eight-byte headers and even-byte padding, requiring a preceding format chunk.
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.

|---|---|---|---|
| oracle 1 | [[[20, 16], [44, 3], [56, 2]], 58] | [[[44, 3], [56, 2]], 58] | Failed |
