Should be easy to add individual outputs for the bands but it just had not seemed that useful to me. Get the CVS version it is rather more satisfactory then the tarball which is horribly broken. http://www.spamblock.demon.co.uk/louderbox.html for the rather hairy details. CPU Load is rather (very much) on the high side as optimisation has not exactly happened yet. Regards, Dan.

A commandline might look something like this: ecasound -a:1,2,3,4,5,6,7,8 -i:jack_alsa \ -a:1 -o:band1.wav \ -a:2 -o:band2.wav \ -a:3 -o:band3.wav \ -a:4 -o:band4.wav \ -a:5 -o:band5.wav \ -a:6 -o:band6.wav \ -a:7 -o:band7.wav \ -a:8 -o:band8.wav \ -a:1 -efl:<cutoff-freq> \ -a:2 -efb:<center>,<width> \ -a:3 -efb:<center>,<width> \ -a:4 -efb:<center>,<width> \ -a:5 -efb:<center>,<width> \ -a:6 -efb:<center>,<width> \ -a:7 -efb:<center>,<width> \ -a:8 -efh:<cutoff-freq> -create 8 chains, 1-8, with jack used as input for each. -assign output individually for each of the eight chains to its own file. These could be output to jack instead if desired. -add a filter to each chain: -efl is a lowpass filer, -efb a bandpass and -efh a high pass. Any additional effects per chain would be tacked on to the end of the line for each filter band. If you so desire the parameters of the effects can be controlled via midi CC, arbitrary envelopes or oscillators. If you are not pleased with ecasound's builtin filters you can easily use any LADSPA filter instead. If the commandline becomes too cumbersome the settup can be stored and edited in a .ecs (ecasound chain settup) file. There is also an interactive ncurses console interface based on the ECI (ecasound control interface). ECI itself can be scripted from C, C++, python, perl, ruby, php and emacs-lisp. The ecasound documentation is included with the package and available online here: http://www.wakkanet.fi/~kaiv/ecasound/Documentation/ Hope that helps, Eric Rz.
