We currently have speex noise suppression enabled by default. You can find some references to the algorithms used at: http://git.xiph.org/?p=speex.git;a=blob;f=libspeex/preprocess.c I've seen it reduce background and fan noise, but I've not got the skillz to understand with the actual method/algorithm myself. -- Arun _______________________________________________ pulseaudio-discuss mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
