ID3 tags library (part of MAD project)
MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 as well as the MPEG-2 extension to Lower Sampling Frequencies. All three audio layers Layer I, Layer II, and Layer III a.k.a. MP3 are fully implemented.
MAD does not yet support MPEG-2 multichannel audio although it should be backward compatible with such streams or AAC, nor does it support the so-called MPEG 2.5 format.
This is ID3 tag library, which is part of the project.
