- 'madplay' is a command-line MPEG audio decoder and player based on the
- MAD library (libmad). After decoding, 'madplay' sends the output to an
- audio output module. The following audio output modules are provided:
- - Sun audio
- - CD audio (*.cdr, *.cda)
- - Audio IFF (*.aif, *.aiff)
- - Microsoft RIFF/WAVE file (*.wav)
- - Sun/NeXT audio file (*.au, *.snd)
- - raw PCM
- - hex (for debugging and compliance testing)
- - null (for timing the decoder)
- 'madplay' will also read and display ID3 tag information, and further
- supports the relative volume adjustment information (RVA2) in such tags,
- as written by tools like 'normalize'.
- MAD produces output samples with a precision greater than 24 bits. Because
- most output formats use fewer bits, typically 16, 'madplay' implements a
- dithering algorithm when truncating samples for output. This produces high
- quality audio that generally sounds superior to the output of a simple
- rounding algorithm. However, dithering may unfavorably affect an analytic
- examination of the output (such as compliance testing), and therefore it
- may optionally be disabled at runtime.
- Available flavors:
- esd - additional EsounD interface module
