NAME
       WMRecord	- General Purpose Recording Utility for	Linux

SYNOPSIS
       wmrecord	[-d <dsp>] [-m <mixer>]	[-h]

DESCRIPTION
       WMRecord	 is a general purpose recording	utility	for Linux systems run-
       ning X11, currently using the Open Sound	System (OSS) to	access the au-
       dio  subsystem.	The  interface is designed to work in conjunction with
       WindowMaker's Dock or AfterStep's Wharf,	two  popular  window  managers
       for  the	X Window System. An alternative	interface incorporating	a more
       general purpose GUI toolkit is planned but not imminent.

       WMRecord	was originally conceived as a tool for recording memos,	inter-
       views  and meetings, and	this approach is reflected somewhat in the in-
       terface.	Recordings are made to one of  99  numbered  slots  or	tracks
       which  the  user	 may browse through. There is no limit (other than the
       constraints of the file system) to the  size  of	 recording  you	 make.
       Recordings  are	automatically  saved  to  disk,	 but  may be erased or
       recorded	over as	necessary.

       The user	may select the input source, line quality and bit rate of  the
       recording  as  well  as determining whether or not to record in stereo.
       All settings are	automatically saved by the program, so there  need  be
       no  fiddling  with  configuration files in order	to manipulate the set-
       tings.

       Version 1.0.5 now uses the WAVE file format for recording samples. This
       should  allow  users  to	 import	recordings into	other applications and
       therefore increase the usefulness of WMRecord. However, recordings made
       with version 1.0.0 will no longer be playable with the new release.

OPTIONS
       By default, WMRecord uses the devices /dev/dsp and /dev/mixer to	manip-
       ulate the audio hardware. There is currently no way to change this from
       the  interface,	but  it	 is possible to	override these settings	at the
       command line using the following	switches:

       -d <dsp>
	      Set the DSP audio	device.

       -m <mixer>
	      Set the Mixer device.

       The main	display	area of	the interface shows the	length of the  record-
       ing  in	seconds	 (or in	playback mode, the number of seconds elapsed),
       the recording source (icons representing	either a  microphone,  a  line
       jack  or	 a  CD)	 and the sample	rate. Two green	LEDs represent mono or
       stereo mode and two red LEDs represent 8-bit or 16-bit sound quality.

       Directly	underneath are the Record, Stop	and Playback buttons  and  un-
       derneath	 that  is the track selection which comprises a	display	of the
       current track number, Previous Track and	Next Track  buttons,  and  the
       Erase  track  button.  Using the	right mouse button on the Previous and
       Next track buttons changes the volume.

       Arranged	from top to bottom on the right	hand side of the interface are
       controls	 for  selecting	the Input Source (either Mic, Line or CD), the
       Sample Rate (either 8000, 11025,	22050 or 44100),  the  Mono  /	Stereo
       toggle and the 8-bit / 16-bit toggle.

FILES
       All  files  are stored in the directory $HOME/.wmrecord.	Recordings are
       listed "rec01.wav" ... "rec99.wav", while  the  configuration  file  is
       called "wmrecordrc".

CAVEATS
       WMRecord	uses the OSS (Open Sound System) as its	interface to the audio
       hardware. WMRecord also assumes that  samples  are  little-endian.   As
       such, this means	that WMRecord is probably limited to the x86 architec-
       ture.

       There is	no processing of the recorded audio. This means	that there  is
       no noise	filtering, and data is written to disk uncompressed.

       8-bit data does not appear to be	recorded correctly.

       There is	no more	space on the interface for new buttons.	*sigh*

CREDITS
       The  interface is based on an excellent dockapp called WMTune, with the
       input source icons being	taken from another excellent  app  called  WM-
       Mixer. Well, I'm	not too	good at	drawing	fiddly little things and these
       applications look great.	The sources for	WMTune (and other dockapps for
       that  matter)  also came	with a general purpose dockapp library which I
       have also used for creating the window and copying  pixmaps  around.  I
       think  that this	should be packaged up into a separate library for Win-
       dowMaker	/ Afterstep as it really cuts down the	number	of  hoops  you
       have to jump through in order to	please Xlib.

TO BE DONE
       -      Find  a  better way to update the	configuration file. Normally I
	      would have left all updates until	the program received a	signal
	      or  a  DestroyNotify event but this does not seem	to achieve the
	      desired effect in	WindowMaker.

       -      Implement	a method for selecting the dsp and mixer devices with-
	      out the need for command line switches.

       -      Fix  the	playback timing	bug: the playback counter updates more
	      rapidly than the rate at which the recording  is	being  output,
	      unless high quality settings are specified.

       -      Allow a user to impose a maximum recording time.

       -      A	configure script or Imake setup, perhaps?
