Hi!
I am happy to announce that the aRts C API - which allows you to send
streams of samples to the aRts sound server using plain C - is ready
for public use. This means, you can now grab any software package you
like and turn it into an aRts aware software package with a few lines
of code. ;-)
Background: artsd is a sound server based on the aRts/MCOP multimedia
component technology. A sound server allows you to let many applications
use the audio device at the same time. So it allows you do listen to
music, while still playing a game. For instance, you can now play Quake
and listen to mp3s. And still get an audible notification when you got
new email. Of course, this is much more fun when more applications are
aRts aware.
To show how easy porting is this, I did the port for two apps, namely
- Quake (patch against quakeforge-0.1.1) => it has good response times ;-)
- Mpg123 (patch against mpg123-0.59r)
It was really little work (besides writing the API of course). The snd_arts.c
driver for quake for instance is the smallest of all sound drivers with
about 160 lines of code, which are mostly copied from the other quake
sound drivers.
The necessary aRts code is in the KDE-2.0 CVS where the other aRts stuff
lives. But there are also standalone snapshots, which dont require X11,
Qt or KDE to work. The snapshots are available at:
http://space.twc.de/~stefan/kde/arts-snapshot-doc.html
And here is the URL where you can documentation for the C API & the patches:

Any comments to the API or more patches are of course welcome. Expect the
first "official" releases of aRts soon.
Cu... Stefan
