[-dhILqS] [-f <rc file>][-C <color scheme file>]
This program adjusts the settings of an audio mixing device. It can be used from
the command line, in scripts, or interactively with the keyboard or mouse.

and decrement by one, or an amount if one is specified. If no
after the channel option, a number sets a specific level (monophonically).
- specify the name of a file containing a color scheme. This
implies -I. The color scheme file may reside
in the current working directory or in the
aumix data directory, typically
/usr/share/aumix-gtk if you are using the
GTK-enabled aumix package. This option can be
used to force the ncurses interface with a GTK version. No need to specify
a filename in that case.
- specify the name of the mixer device (default is
- specify file for saving and loading settings
- display information on usage
- run aumix interactively, using
the full-screen ncurses-based interface. This is the default if no options
are given, but must be specified in order to have
aumix go into interactive mode after doing
To force use of the ncurses interface with the GTK version, specify -C (no
need to give a filename).
- load settings from
/etc/aumixrc if the former is
- query all devices and print their settings
- save settings to
aumix -q -v75 -m 0 -c R -c+10 -m q
prints all settings, sets volume to 75%, sets microphone to 0, sets CD to
record, increases the CD level by ten (both left and right), and prints the
new settings for the microphone.
The .aumixrc file containing:
sets the volume to 60%, waits five seconds, then reduces the volume to 50%. Note
that "wait" lines will not be saved by aumix. They must be added by
If no options are given on the command line, and

The left bank of controls is used for adjusting levels; the right bank is for
adjusting balance. Mixing channels not supported by your hardware will not be
shown. Mixing channels which are stereo-capable will have balance controls.
The following keys control aumix
- page up, page down, up and
- select a new control.
- Tab, Enter, <, >,
comma and period
- toggle between level and balance controls
- +, -, [, ], left and right
cursor and digits
- adjust the setting of the current device. The
+ and right cursor keys increase the level by 3%;
- and left cursor keys decrease it by the same
[ key sets it to 0% and
0 set it to 100%. The
9 set it to
10% through 90%. The digit
0 sets it to 100% (not
0%). The same keys work analogously on the balance controls.
- toggles between record and play for controls which are
capable of this.
- centers the balance of the current device.
- K or k
- show a description of the functions of keys
- L or l
- load settings from
$HOME/.aumixrc, falling back to
- M or m
- mute or unmute
- O or o
- “only”: mute all channels but the current
- S or s
- save settings to the rc file
- U or u
- undo any muting
- Q or q
- end the program
- refresh screen
^Z, ^D and ^C also have their normal function (the screen is refreshed when
is brought to the foreground).
In interactive mode, aumix
can accept input from
the mouse if gpm(8)
is running and
is compiled with
support. If gpm is not running but gpm
support is included, the message ‘
’ will appear at the top of the screen, and only keyboard
input will be accepted. With gpm(8)
functions can be performed through the mouse. The mouse is active whenever one
of its buttons is held down. While active, it works in the following ways:
- over a control track, it sets the control to match the
position of the mouse cursor.
- over a record/play indicator, it toggles the record/play
- over the ‘
Undo’ labels at the top of the
screen, it causes those actions to take place.

Saved settings for the mixer are kept in the
files, but can be kept anywhere if
specified explicitly. Color schemes are normally kept in the directory given
at compilation time, but are
preferentially loaded from the current directory and can be kept anywhere so
long as the path to them is specified. The format of these files is:

by whitespace and can be upper-, lower-, or mixed-case. Lines not matching all
these conditions are ignored. Some samples of color schemes are provided,
named after the sort of terminal where they should be most suitable.
If either foreground or background is given as
’, then the default color for that is
used. If aumix is linked against ncurses, then the terminal's default fore or
background will be used; else the default foreground is white and the default
background is black.
An xpm icon is provided.

Suspending with ^Z may make the terminal difficult to use.
