View Full Version : KDE 4, Phonon and Crossfeed

To those who don't know what crossfeed is, here's a quick explanation. With speakers, you hear some of the right hand channel in your left ear, and vice versa. With headphones, of course, this does not happen. Crossfeed does this mixing electronically, and can make listening to certain tracks much more comfortable. It is found as a plugin in the Rockbox (http://www.rockbox.org) project, and also in several apps for Windows/Mac OS.

However, I have never found anything similar for Linux. I've been following KDE 4 development loosely, and have noticed that the new Phonon component seems to have an "Audio Effect" plugin capability (from looking at the API documentation). Does anybody know if this can, or will, be used to provide real-time audio effects such as crossfeed to Linux (well, KDE, I suppose) applications?

If you want a direct answer, I'd recommend contacting Matthias Kretz - he's a nice guy :) You can probably find his e-mail via Google (here is his blog (http://vir.homelinux.org/blog/)). He's also often found in #kde4-devel on irc.freenode.net with the nickname "Vir".

Hope this helps!
