… a small utility for analysis of audio mpeg files and detection of the encoder used (when layer III).
Further, mp3guessenc can detect many details about the mpeg audio stream and print out lots of useful information.
Supported streams are mpeg 1, mpeg 2 and unofficial mpeg 2.5 – layer I, layer II and layer III of course. Xing tag, lame tag, VBRI tag, Id3 tags (both 1.x and 2.x), APE tags (both v1 and v2), Lyrics3 tags (both v1 and v2) and MusicMatch tag (any version) are detected as well.
Features:
- scan mpeg 1/2/2.5 streams, layer I/II/III
- guess encoder used (lame/gogo/xing/helix/fhg(new, old and ancient)/blade)
- also detects mp3pro and mp3surround streams (even with OFL)
- support for large files (up to 2^60 bytes!)
- free format streams supported
- full statistics for the stream (audio mode, frame histogram, block usage, ancillary data)
- crc16 verification
- vbr tags by xing/lame + VBRI tag by fhg
- detection of ID3 v1/v2 + APE tags + Lyrics3 tags + MusicMatch tag
- verify integrity of lame tag
