M4A Sample Files
M4A (.m4a) encapsulates AAC or ALAC audio within an MP4 container, adding support for chapter markers and metadata atoms. Common on Apple platforms, it’s ideal for music and podcasts. Use sample .m4a files to test container parsing, chapter navigation, and artwork extraction.

Validation Methodology
- Verify duration, sample rate, and channel count in your decoder.
- Test metadata extraction and malformed-tag handling.
- Validate seek/stream behavior over slow networks.
