.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program copies the audio devices to the named audiofile, or the standard
|
|
output if no file is named.
|
|
The output file will contain a Sun/NeXT audio header.

|
|
The following options are available:

Append to the specified file, rather than overwriting.
|
|
.It Fl b
|
|
Set the balance to
|
|
.Ar balance .
|
|
This value must be between 0 and 63.
|
|
.It Fl C
|
|
Set the audio control device to be
|
|
.Ar ctl .
|
|
The default is
|
|
.Pa /dev/audioctl0 .
|
|
.It Fl d
|
|
Set the audio device to be
