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.
