 decoded by sox and Audacity.
 > This seems unlikely to me: The last frame consists of 47 bytes (instead
 of 626 or 627), has no frame header (all other frames start with "0xff
 0xf5 0xa2") and contains (non-readable) uncompressed data.

 Synchronisation lost: 0 (0x00000000) that is how. See Mediainfo.
