A wrapper for the MAD (mpeg audio decoder) library.
Project description
pymad - a Python wrapper for the MPEG Audio Decoder library
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.
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))
The latest release is available for download at https://pypi.org/project/pymad/
or via pip install pymad
. They're replicated on GitHub in the Releases section.
To build locally, the usual python -m build
or python -m pip install .
works.
The tests require manual interaction (because you want to listen to the decoded output) and requires PyAO on Linux.
