zita-ajbridge (ALSA <=> JACK bridge) zita-ajbridge provides two applications, zita-a2j and zita-j2a. They allow using an ALSA device as a Jack client, to provide additional capture (a2j) or playback (j2a) channels. Functionally these are equivalent to the alsa_in and alsa_out clients that come with JACK, but they provide much better audio quality. The resampling ratio will typically be stable within 1 PPM and change only very smoothly. Delay will be stable as well even under worst case conditions, e.g. the JACK client running near the end of the cycle. This package uses POSIX filesystem capabilities to execute with elevated privileges (required for realtime audio processing). This may be considered a security/stability risk. Please read http://www.slackbuilds.org/caps/ for more information. To disable capabilities, pass SETCAP=no to the script.
