JAMIN(1)			     Audio			      JAMIN(1)

NAME
       jamin - JACK Audio Mastering interface

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

       jamin-scene _scene-num_

DESCRIPTION
       The  jamin  command  invokes  JAMin, the	JACK Audio Mastering interface
       which is	based on the JACK Audio	Connection Kit,	<http://jackit.source-
       forge.net>.

       JAMin is	designed for professional stereo audio mastering.  It provides
       of a number of tools: a 1024-band hand-drawn EQ	with  parametric  con-
       trols,  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 <http://jamin.sourceforge.net>.

OPTIONS
       -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.

       -h
	      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
	      server.

       -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  up-
	      date.

       -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  combina-
	      tion  with large jack buffer sizes may introduce zipper noise to
	      some signals (especially sustained sounds	in the bass range).

       -p
	      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.

       -i
	      Use  IIR	type  crossover	instead	of the default FFT type	cross-
	      over.  The IIR crossover is  less	 CPU  intensive	 but  the  FFT
	      crossover	may give better	results	(YMMV).

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

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

       -V     Print version and	copyright information, then quit.

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

       ~/.jamin/jamin_ui
	      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/exam-
	      ples/jamin_ui.	To   customize	 that	file,	copy   it   to
	      ~/.jamin/jamin_ui	and make changes.

       ~/.jamin/*.jam
	      Normal  location	for  user-defined  session files.  They	can be
	      stored elsewhere,	if desired.

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

IPC
       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 num-
       ber  to	change.	 A  commaind line tool (jamin-scene) and LADSPA	Plugin
       (jamin_cont, ID:1912) are provided for remote scene changes.

EXAMPLES
       Since jamin is not a standalone program we generally  need  other  pro-
       grams to	provide	input audio and	receive	the mastered output.  This ex-
       ample 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
       control.

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

       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  destina-
       tion.  In ardour, run all of your track outputs into a stereo bus, con-
       nect 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  ses-
       sion, it	will automatically reconnect all these ports.

	      qjackctl &
	      jamin &
	      ardour
