**Consistent 209ms delta** suggests network/encoding delay between file upload initiation (filename) and actual audio stream start (metadata).
**Consistent ~200ms delta** suggests network/encoding delay between file upload initiation (filename) and actual audio stream start (metadata).
**Note:** The ~200ms difference observed in this test recording is not crucial for timing accuracy. Either method (filename timestamps or PyAV metadata) works well for multi-track alignment. Filename timestamps are preferable as they are better officially documented by Daily.co.
**Current implementation uses PyAV metadata** because:
- More accurate (represents when audio actually started)
