       jamin - JACK Audio Mastering interface


       jamin [ options ] [ inport1 inport2 [ outport1 outport2 ]]

       jamin-scene <scene-num>


       The  jamin  command  invokes  JAMin, the JACK Audio Mastering interface
       which   is    based    on    the    JACK    Audio    Connection    Kit,

       JAMin is designed for professional stereo audio mastering.  It provides
       of a number  of  tools:  a  1024-band  hand-drawn  EQ  with  parametric
       controls,  a 31-band graphic EQ, 3-band compressor, 3-band stereo width
       control, lookahead limiter, boost, and other features.

       For the latest JAMin information, see <>.


       -f filename
              Load session file filename on startup.  If no  session  file  is
              specified, JAMin loads "~/.jamin/default.jam" if that exists, or
              else uses some system-provided default settings.

              Print a brief usage message describing the main  jamin  options,
              including  some developer options not intended for normal users.

       -j servername
              Connect to JACK server servername.  Otherwise, use  the  default

       -n clientname
              Set  JACK  clientname  used  to identify input and output ports.
              Otherwise, use "jamin".

       -s frequency
              Set the spectrum update frequency (per second).  The range is  1
              to  10  with  10  as  the default.  Set to 0 to disable spectrum

       -c time
              Set the crossfade time in seconds.  The range is 0.0 to 2.0 with
              1.0   as   the   default.   WARNING:  fast  crossfade  times  in
              combination with large jack buffer sizes  may  introduce  zipper
              noise  to  some signals (especially sustained sounds in the bass

              Don’t automatically connect any JACK output ports.

              Without this option, JAMin will connect to outport1 and outport2
              if  they were explicitly listed on the command line.  If not, it
              connects to the first two physical output ports with the  string
              ":playback" in their names.

              Use   IIR  type  crossover  instead  of  the  default  FFT  type
              crossover.  The IIR crossover is less CPU intensive but the  FFT
              crossover will give better results (YMMV).

              Set  to  0  to use Steve Harris’ fast-lookahead-limiter or 1 for
              Sampo Savolainen’s foo-limiter.  At this time there is a problem
              with the foo-limiter if you push the input too hard.

              Load  GTK  resource  information  from an example JAMin resource
              file.  If the -r option is  not  specified,  look  for  a  user-
              defined  resource file in ~/.jamin/jamin_ui.  Otherwise, use the
              system-wide GTK settings.

              Print verbose output.  Use -vv or -vvv for more detail.

       -V     Print version and copyright information, then quit.


              Directory containing per-user JAMin data.  Created automatically
              if it does not already exist.

              Default resource file for GTK user interface customization, used
              when the -r command option is not specified.  JAMin  provides  a
              default               resource              file              in
              ${prefix}/share/jamin/examples/jamin_ui.   To   customize   that
              file, copy it to ~/.jamin/jamin_ui and make changes.

              Normal  location  for  user-defined  session files.  They can be
              stored elsewhere, if desired.

              If this session file exists, it is loaded by default on startup,
              except when overridden by the -f option.


       If JAMin has been built with OSC support enabled it responds to UDP OSC
       messages on port 4444.

       Messages to /jamin/scene with a  numerical  argument  cause  the  scene
       number  to change. A commaind line tool (jamin-scene) and LADSPA Plugin
       (jamin_cont, ID:1912) are provided for remote scene changes.


       Since jamin is  not  a  standalone  program  we  generally  need  other
       programs  to provide input audio and receive the mastered output.  This
       example uses alsaplayer  with  output  going  to  the  first  two  ALSA
       playback ports:

              jackd -R -d alsa -p 2048 -r 44100 &
              alsaplayer -o jack -s src -d noconnect song.wav &
              jamin src:out_1 src:out_2

       That  was  the  brute force method.  It is much easier to have qjackctl
       start the JACK server and handle its connections.  After the server  is
       running,  start  jackplayer  and  jamin.   The "transport" option tells
       jackplayer (an alsaplayer alias) to start and stop under JACK transport

              qjackctl &
              jackplayer -d noconnect/transport song.wav &

       Any  JACK-aware player such as rezound, ecasound or ecamegapedal can be
       used, instead.

       A  more  advanced  technique  uses  ardour  for  both  the  source  and
       destination.   In  ardour,  run all of your track outputs into a stereo
       bus, connect its output ports to JAMin, then run the JAMin outputs back
       into  a  record-enabled stereo track.  This allows mixing and mastering
       at the same time.  If JAMin is already running when ardour reopens  the
       session, it will automatically reconnect all these ports.

              qjackctl &
              jamin &

       Steve  Harris  is  the  principal  JAMin author and team leader.  Other
       developers include: Jan  Depner,  Jack  O’Quin,  Ron  Parker,  Emmanuel
       Saracco,  and  Patrick  Shirkey.   Alexandre  Prokoudine  and  Yuri  N.
       Sedunov  developed  the  translation  infrastructure.   Alexandre  also
       translated JAMin into Russian and is our (really good) web engineer.
