madxlib

madxlib is a C/C++ source code to create a Windows DLL that performs buffer-based MP3 decoding. It allows you to build interfaces that can process a given MP3 file in chunks, at intervals you specify, and returns the decoded 16-bit PCM samples in a buffer.

It uses the powerful open source library libmad for MP3 decoding. The design was taken from the source for madlld, whose purpose was to demonstrate libmad's low-level API.

Downloads:

• Current Release
• madxlib SDK

madxlib was designed using a "Makefile" and needs only the .NET SDK (available for free) to compile. The demo includes the compiled DLL and a test program (screenshot below). The test source demonstrates the API usage. It takes an input MP3 file and converts it to a raw PCM output file. See the article Programming the madxlib API, which was submitted to The Code Project, for details. Also see the comments in the sources.
