Audio::Extract::PCM::Backend::Mad - mad backend for audio extraction
This module makes Audio::Extract::PCM capable to use the libmad library (specifically Audio::Mad) for audio extraction.
Unless Sys::Mmap::Simple is available, the MP3 encoded data will be read into memory completely. This is a few megabytes for typical music files, but may be some hundred MB or more for radio broadcasts, music albums or whatever strange applications you find for this module.
If Sys::MMap::Simple is installed, it will be used automatically.
Audio::Mad version 0.6 from 2003 has problems. Consider applying the patch from http://rt.cpan.org/Public/Bug/Display.html?id=42338 until Audio::Mad releases a fixed version.
