===========================================================
[](https://travis-ci.org/jaqx0r/pymad)
pymad is a Python module that allows Python programs to use the MPEG Audio Decoder library. pymad provides a high-level API, similar to the pyogg module, which makes reading PCM data from MPEG audio streams a piece of cake.
MAD is available at http://www.mars.org/home/rob/proj/mpeg/
Access this module via `import mad`. To decode
an mp3 stream, you'll want to create a `mad.MadFile` object and read data from
that. You can then write the data to a sound device. See the example
program in `test/` for a simple mp3 player that uses the `python-pyao` wrapper around libao for the sound
device.
pymad wrapper isn't as low level as the C MAD API is, for example, you don't
have to concern yourself with fixed point conversion -- this was done to
make pymad easy to use.
```python
import sys
import ao
import mad
mf = mad.MadFile(sys.argv[1])
dev = ao.AudioDevice(0, rate=mf.samplerate())
while 1:
buf = mf.read()
if buf is None: # eof
break
dev.play(buf, len(buf))
```
To build, you need the distutils package, availible from
http://www.python.org/sigs/distutils-sig/download.html (it comes with
Python 2.0). Run "python setup.py build" to build and then as root run
"python setup.py install". You may need to run the config_unix.py
script, passing it a --prefix value if you've installed your mad stuff
someplace weird. Alternately, you can just create a file called
"Setup" and put in values for mad_include_dir, mad_lib_dir, and
mad_libs. The file format for Setup is:
key = value
with one pair per line.
```shell
# python config_unix.py --prefix /usr/local
# python setup.py build
# python setup.py install --prefix /usr/local
```
Remember to make sure `/usr/local/python/site-packages/` is in your Python search path.
