Binary package “zita-ajbridge” in ubuntu jammy
alsa to jack bridge
This package provides two applications, zita-a2j and zita-j2a.
They allow one to use 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 worse case conditions, e.g. the Jack client
running near the end of the cycle.
