• The audio player supports reading of ALAC content stored in mp4 containers. Supported

NOTE: There is no specification for tag names. The system relies on the OSS implementation.
• Tag names decoded: TITLE, ALBUM, ARTIST, GENRE.

NOTE: For correct gapless decoding, the container must provide correct encoder delay metadata (or no encoder
delay at all!), which is dierent from lossy compression formats like AAC.
