NAME

       calf - a audio plugin library

SYNOPSIS

       calfjackhost plugin !  [ plugin !  ] [...]

DESCRIPTION

        The  Calf  project  aims  at  providing  a  set of high quality open source audio plugins for musicians,
       possibly in many different plugin formats, so that they can be used in as many hosts as possible  and  in
       standalone mode.  Currently available plugins:

           *  Flanger with linear interpolation. In case "zipper noise" of basic flanger effects was driving you
       mad, use this one!
           * Simple reverb with basic controls and relatively neutral sound. No dreaded metal barrel  sound,  at
       expense of higher CPU use and less time density.
           *  Multimode  filter  (selectable 12dB/24dB/36dB rolloff, lowpass or highpass) with inertia/smoothing
       for cutoff for more "analog" sound when tweaking.
           * Vintage delay - in other words, a very simple simulation of tape echo, with a filter in a  feedback
       loop.
           * Simple monophonic synthesizer with 2 oscillators, multimode filter and an envelope.
           *  Optional:  electric  organ  synthesizer  and  rotary  speaker  emulation,  best used together (use
       "configure --enable-experimental" to enable them) The plugins are available in following formats:

           * LADSPA (all effect plugins)
           * DSSI (both synthesizers and effects), including DSSI GUI
           * Standalone JACK client application with GTK+-based GUI (new: it is possible to run several  plugins
       simultaneously in one JACK client, and connect them in chains using standard JACK facilities)
           *  LV2  (experimental,  SVN  only,  some features may not work, host support for several features may
       vary)

OPTIONS

        How to use Calf plugins:

        * LADSPA plugins

              Calf is installed as calf.so library in your  LADSPA  directory  (typically  /usr/lib/ladspa).  It
              means that typical LADSPA host should be able to find Calf's plugins.

        * DSSI plugins

              The  calf.so  module  is  also installed in your DSSI plugin directory, which means your DSSI host
              (like jack-dssi-host or rosegarden) should find it and include its plugins in the plugin list.

        * JACK client application

              You can also use  Calf  plugins  as  one  or  more  separate  applications,  connecting  to  other
              applications  using  JACK  Audio  Connection  Kit (version 0.103 or newer is required). To run the
              client, type:

                      calfjackhost monosynth !

              (! means "connect", last "!" means "connect to output")

              Other examples:

                      calfjackhost monosynth ! vintagedelay ! flanger !

              (runs monosynth into vintagedelay and vintagedelay into flanger, then to output)

                      calfjackhost ! reverb !

              (takes  signal  from  system:capture_1  and  _2,  puts  it  through  reverb,  and  then  sends  to
              system:playback_1 and _2)

ENVIRONMENT

       LADSPA_PATH Path to LADSPA plugins.

BUGS

       LV2  support  is  in  infant  stage.  Some  knobs  may  still  cause clicks/zipper noise. Plugin versions
       (especially LADSPA) have very poor usability  comparing  to  standalone  versions,  because  of  platform
       limitations.  In case of other bugs, please send bug reports to <wdev@foltman.com>, they will be fixed in
       order of importance.
