\fB\-t\fP | \fB\-\-test\fP \fBpink\fP|\fBsine\fP|\fBwav\fP
|
|
\fB\-t pink\fP means use pink noise (default).
|
|
|
|
Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once. If you can hear any tone it may indicate resonances in your speaker system or room.
|
|
|
|
\fB\-t sine\fP means to use sine wave.
|
|
|
|
\fB\-t wav\fP means to play WAV files, either pre-defined files or given via \fB\-w\fP option.
|
|
|
|
You can pass the number from 1 to 3 as a backward compatibility.
|
|
|
|
.TP
|
|
\fB\-l\fP | \fB\-\-nloops\fP \fBCOUNT\fP
|
|
|
|
Specifies the number of loops. Zero means to run inifintely.
|
|
|
|
When \fB\-s\fP option below with a valid channel is given, \fBspeaker\-test\fP will perform
|
|
always a single-shot without looping.
|
|
|
|
.TP
|
|
\fB\-s\fP | \fB\-\-speaker\fP \fBCHANNEL\fP
|
|
Do a single-shot speaker test for the given channel. The channel number starts from 1.
|
|
The channel number orresponds to left, right, rear-left, rear-right, center, LFE,
|
|
side-left, side-right, and so on.
|
|
|
|
For example, when 1 is passed, it tests the left channel only once rather than both channels
|
|
with looping.
|
|
|
|
.TP
|
|
\fB\-w\fP | \fB\-\-wavfile\fP
|
|
Use the given WAV file for the playback instead of pre-defined WAV files.
|
|
|
|
.TP
|
|
\fB\-W\fP | \fB\-\-wavdir\fP
|
|
Specify the directory containing WAV files for playback.
|
|
The default path is \fI/usr/share/sounds/alsa\fP.

.SH USAGE EXAMPLES
|
|
|
|
Produce stereo sound from one stereo jack:
|
|
.EX
|
|
speaker-test -Dplug:front -c2
|
|
.EE
|
|
|
|
Produce 4 speaker sound from two stereo jacks:
|
|
.EX
|
|
speaker-test -Dplug:surround40 -c4
|
|
.EE
|
|
|
|
Produce 5.1 speaker sound from three stereo jacks:
|
|
.EX
|
|
speaker-test -Dplug:surround51 -c6
|
|
.EE
|
|
|
|
To send a nice low 75Hz tone to the Woofer and then exit without touching any other speakers:
|
|
.EX
|
|
speaker-test -Dplug:surround51 -c6 -s1 -f75
|
|
.EE
|
|
|
|
