NAME
xmmix - Audio mixer utility for X11/Motif
SYNOPSIS
xmmix [toolkitoption ...] [-dev device] [-autoload path]
[-exitreset] [-debug] [-demo]
DESCRIPTION
Xmmix is a program that allows the use of the mixer section
of the sound card hardware supported by the VoxWare driver.
See the README file in the xmmix distribution for further
information about VoxWare.
There are up to ten input level sliders (Synth, PCM, Alt
PCM, Line, Line-1, Line-2, Line-3, Mic, CD) and up to four
output level sliders (Rec Mon, Rec Out, Speaker and Master).
The Input Gain control, Output Gain control, Bass and Treble
tone control sliders are also available. Each of the level
sliders include a "lock" toggle button which allows the
settings of the two stereo channels to be changed
simultaneously or independently. The input controls also
include a "rec" button (where applicable), which allows the
input sources to be selected for recording. The tone
control sliders have a "Flat" button which causes these
controls to revert to the center setting. In addition,
these controls are available: a "Mute" button to silence the
audio, a "Loudness" button to engage frequency response
compensation, and an "Stereo Enhance" button to set the
stereo separation enhancement.
Xmmix queries the capabilities of the sound board during
start-up, and will only display controls corresponding to
features that are actually implemented in the hardware.
The various controls in the xmmix main window are meant to
be self explanatory. Additional features include the
ability to save mixer settings in a file and load it at a
later time. A "Reset" feature resets all controls to their
start-up settings.
While the use of a mouse is natural with xmmix, all
functionality can also be operated via the keyboard. This
is in conformance to the guidelines published in the
OSF/Motif Style Guide from the Open Software Foundation.
OPTIONS
All standard Xt Intrinsics toolkit options are supported.
In addition, xmmix supports the following options:
-dev device
Specifies the path name to the raw mixer device. If
this option is not used, the default device used is
/dev/mixer.
-autoload path
Specifies the path name to a mixer settings file that
is automatically loaded when xmmix starts. This forces
all control settings to those specified in the file.
If this option is not used, then the control settings
will be queried from the mixer hardware itself. This
option overrides the XMmix*autoLoadOnStartUp X
resource.
-exitreset
Causes all mixer controls to reset to their start-up
state when xmmix is exiting. This option overrides the
XMmix*resetOnExit X resource.
-debug
Causes verbose debugging diagnostics to be printed on
stderr.
-demo
Invokes xmmix in "demo" mode. This causes xmmix to
display all controls as if they are functional, but
does not actually operate the sound hardware.
X RESOURCES
Xmmix has many adjustable X resources to customize its look
and feel, as well as its behavior. Notably, the colors of
virtually every feature on xmmix's windows can be changed,
as well as the text fonts.
The resource names and their defaults can be found in the
LIBDIR/app-defaults/XMmix file (where LIBDIR is typically
/usr/lib/X11). It is not recommended that you change values
in the LIBDIR/app-defaults/XMmix file, unless you want the
changes to be forced upon all users of xmmix on the system.
Instead, make a copy of this file, change the copy as you
see fit, then place it in your home directory. Your custom
resource settings will then override the defaults when xmmix
is subsequently started. Alternatively, you may also place
specific resources you wish to override in the .Xdefaults
file in your home directory.
