zita-rev1 is a reworked version of the reverb originally developed for Aeolus. Its character is more 'hall' than 'plate', but it can be used on a wide variety of instruments or voices. It is not a spatialiser - the early reflections are different for the L and R inputs, but do not correspond to any real room. They have been tuned to match left and right sources to some extent. 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.
