audiolayer 0.1.1

This module provides a wrapper around the libav C library

This package contains a Python 3 Extension for playing audio files, reading and writing metadata and converting those files. For decoding and encoding files the libav library is used. Playback is handled by libportaudio.

The project website can be found at GitHub.

Requirements

• python3.x (Tested using python3.3)

• libavcodec

• libavformat

• libavutil

• libportaudio

Installation

Using pip:

pip install audiolayer

From GitHub:

git clone https://github.com/remcohaszing/python-audiolayer.git
cd python-audiolayer
python3 setup.py install

Usage

Reading song metadata:

>>> from audiolayer import Song
>>> filename = 'Finntroll - Trollhammaren.flac'
>>> song = Song(filename)
>>> song['artist']
Finntroll
>>> song['album']
Trollhammaren
>>> song['title']
Trollhammaren
>>>

Saving song metadata:

>>> song['album'] = 'Nattfödd'
>>> song['album']
'Nattfödd'
>>> song.save()
>>>

Saving a copy of the song with the new metadata to a new file: >>> song.save(filename=’Finntroll/Nattfödd - Trollhammaren.flac’) >>>

Converting the song (not implemented):

>>> converted = song.convert('Finntroll - Trollhammaren.ogg',
...                          format='opus', q=4)
>>> converted.filename
Finntroll - Trollhammaren.ogg
>>>

Playback (current implementation):

>>> song.play()  # Wait for the song to finish.
>>>

Playback (target implementation):

>>> song.play()
0.00
>>> song.pause()
4.29
>>> song.play_or_pause()
4.29
>>> song.playing_time
12.53
>>>

Testing

The unittests can be run using:

python3 setup.py test

It is also possible to use nose to run the tests:

python3 setup.py nosetests

Coding style

• C code must be in compliance with pep7.

• Python code must be in compliance with pep8.

• All code must be covered by unittests.

To test the Python code for pep8 compliance, go to the project root directory and run:

python3 setup.py flake8
