Audio in Python
This page tries to provide a starting point for those who want to work with audio in combination with Python.
If you are creating a game, most of what you are looking for may already be included in the many PythonGameLibraries that are available.
If you are looking for podcasts related to Python, go to the PythonAudioMaterial page.
Built in modules
The Multimedia Services allow for some basic audio functionality in Python. It consists of the following modules:
Manipulate raw audio data. |
|
Read and write audio files in AIFF or AIFC format. |
|
Provide an interface to the Sun AU sound format. |
|
Provide an interface to the WAV sound format. |
|
Module to read IFF (e.g. AIFF) chunks. |
|
Conversions between colour systems. |
|
Determine the type of a image file. |
|
Determine the type of a sound file. |
|
Access to OSS-compatible audio devices (mainly important for Linux / FreeBSD) |
|
Access to the basic sound-playing machinery provided by Windows platforms. |
