If you want to write a volume control application, make sure to read this.
Also, make sure to set properties on all PA connections, make sure to read this.
*Finally, make sure you know everything about latency control! *
When working on PulseAudio, please mind the Coding Style.
There are several reasons for writing loadable modules for PulseAudio:
- Extended device driver support
- Protocol support beyond ESOUND's protocol and the native protocol. (such as NAS or a subset of aRts)
- New programming interfaces such as XMLRPC or DBUS for controlling the daemon.
- Hooking audio event sources directly into PulseAudio (similar to
For low latency applications such as VOIP: load the VOIP core directly into PulseAudio and have a slim GUI frontend to control it. There is currently a little bit of documentation available on how to write loadable modules for PulseAudio. Beyond this, read the source, Luke! If you are interested in writing new modules feel free to contact the authors in case you have any questions.
