MAD ~ MPEG Audio Decoder


MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 and the MPEG-2 extension to lower sampling frequencies, as well as the de facto MPEG 2.5 format. All three audio layers — Layer I, Layer II, and Layer III (i.e. MP3) — are fully implemented.

MAD does not yet support MPEG-2 multichannel audio (although it should be backward compatible with such streams) nor does it currently support AAC.

MAD has the following special features:

  • 24-bit PCM output
  • 100% fixed-point (integer) computation
  • completely new implementation based on the ISO/IEC standards
  • available under the terms of the GNU General Public License (GPL)

mp3guessenc ~ Analyze Audio mpeg Files


… 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

MP3val ~ Validate Your mp3s


MP3val is a small, high-speed, free software tool for checking MPEG audio files’ integrity. It can be useful for finding corrupted files (e.g. incompletely downloaded, truncated, containing garbage). MP3val is also able to fix most of the problems. Being a multi-platform application, MP3val can be run both under Windows and under Linux (or BSD).

The most common MPEG audio file type is MPEG 1 Layer III (mp3), but MP3val supports also other MPEG versions and layers. The tool is also aware of the most common types of tags (ID3v1, ID3v2, APEv2).
