'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.
