|
|
General Controls
|
|
|
|
The \fILeft\fP and \fIright arrow\fP keys are used to select the
|
|
channel (or device, depending on your preferred terminology). You can
|
|
also use \fIn\fP ("next") and \fIp\fP ("previous").
|
|
|
|
The \fIUp\fP and \fIDown Arrows\fP control the volume for the
|
|
currently selected device. You can also use \fI+\fP or \fI-\fP for the
|
|
same purpose. Both the left and right signals are affected. For
|
|
independent left and right control, see below.
|
|
|
|
The \fIB\fP or \fI=\fP key adjusts the balance of volumes on left and
|
|
right channels.
|
|
|
|
\fIM\fP toggles muting for the current channel (both left and right). You can
|
|
mute left and right independently by using \fI,\fP (or \fI<\fP) and
|
|
\fI.\fP (or \fI>\fP) respectively.
|
|
|
|
\fISPACE\fP enables recording for the current channel. If any other
|
|
channels have recording enabled, they will have their recording function
|
|
disabled first. This only works for valid input channels, of course.
|
|
|
|
\fIL\fP re-draws the screen.
|
|
|
|
.SS
|
|
Quick Volume Changes
|
|
|
|
\fIPageUp\fP increases volume by 5.
|
|
|
|
\fIPageDown\fP decreases volume by 5.
|
|
|
|
\fIEnd\fP sets volume to 0.
|
|
|
|
You can also control left & right levels for the current channel
|
|
independently, as follows:
|
|
|
|
[\fIQ\fP | \fIW\fP | \fIE\fP ] -- turn UP [ left | both | right ]
|
|
|
|
[\fIZ\fP | \fIX\fP | \fIC\fP ] -- turn DOWN [ left | both | right ]
|
|
|
|
If the currently selected mixer channel is not a stereo channel, then
|
|
all UP keys will work like \fIW\fP, and all DOWN keys will work like \fIX\fP.
|
|
|
|
.SS
|
|
Exiting
|
|
|
|
Quit the program with \fIALT Q\fP, or by hitting \fIESC\fP.
|
|
Please note that you might need to hit \fIESC\fP twice on some terminals
|
|
since it's regarded as a prefix key.

.SH BUGS
|
|
Some terminal emulators (e.g. \fBnxterm\fP) may not
|
|
work quite right with ncurses, but that's their own damn
|
|
fault. Plain old \fBxterm\fP seems to be fine.
