A truncated TDM frame is reported as a valid empty channel frame.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Stipulated TDM PCM extractor: active mask bits name ascending physical slots; ignore mask bits above slot count and reject incomplete physical frames.

Why this case matters

Offline PCM interchange uses these exact bounded packet and sample representation decisions.

One recorded failure

Sample boundary fixture
