This library is called \textit{libasound} - and is required by all ALSA capable applications. -\end{itemize} - -More information about ALSA may be found on the project homepage -\url{http://www.alsa-project.org} - -\section{ALSA and Python} - -The older Linux sound API (OSS) which is now deprecated is well supported -from the standard Python library, through the ossaudiodev module. No native -ALSA support exists in the standard library (yet). - -There are a few other ``ALSA for Python'' projects available, including at -least two different projects called pyAlsa. Neither of these seem to be under -active development at the time - and neither are very feature complete. - -I wrote PyAlsaAudio to fill this gap. My long term goal is to have the module -included in the standard Python library, but that is probably a while of yet. - -PyAlsaAudio hass full support for sound capture, playback of sound, as well as -the ALSA Mixer API. - -MIDI support is not available, and since I don't own any MIDI hardware, it's -difficult for me to implement it. Volunteers to work on this would be greatly -appreciated -\section{Installation} - -Note: the wrappers link with the alsasound library (from the alsa-lib -package). Verify that this is installed by looking for /usr/lib/libasound.so -before building. Naturally you also need to use a kernel with proper ALSA -support. This is the default in Linux kernel 2.6 and later. If you are using -kernel version 2.4 you may need to install the ALSA patches yourself - although -most distributions ship with ALSA kernels. - -To install, execute the following: \\ -\begin{verbatim} -$ python setup.py build -\end{verbatim} - -And then as root: \\ -\begin{verbatim} -# python setup.py install -\end{verbatim} - -\input{libalsaaudio} - - - - -\end{document} -- cgit v0.9.1
