-.TH SPEAKER\-TEST 1 "20 September 2004" speaker-test
-.SH NAME
-speaker\-test \- command-line speaker test tone generator for ALSA
-.SH SYNOPSIS
-.B speaker\-test [\-options]
-
-.SH DESCRIPTION
-\fBspeaker\-test\fP generates a tone that can be used to test the speakers of a computer.
-
-.SH OPTIONS
-
-.TP
-\fB\-c\fP | \fB\-\-channels\fP \fINUM\fP
-\fINUM\fP channels in stream
-
-.TP
-\fB\-D\fP | \fB\-\-device\fP \fINAME\fP
-PCM device name \fINAME\fP
-
-.TP
-\fB\-f\fP | \fB\-\-frequency\fP \fIFREQ\fP
-sine wave of \fIFREQ\fP Hz
-
-.TP
-\fB\-\-help\fP
-Print usage help
-
-.TP
-\fB\-b\fP | \fB\-\-buffer\fP \fITIME\fP
-Use buffer size of \fITIME\fP microseconds.
-When 0 is given, use the maximal buffer size.
-The default value is 0.
-
-.TP
-\fB\-p\fP | \fB\-\-period\fP \fITIME\fP
-Use period size of \fITIME\fP microseconds.
-When 0 is given, the periods given by \fB\-P\fP option is used.
-The default value is 0.
-
-.TP
-\fB\-P\fP | \fB\-\-nperiods\fP \fPERIODS\fP
-Use number of periods. The default value is 4.
-
-.TP
-\fB\-r\fP | \fB\-\-rate\fP \fIRATE\fP
-stream of \fIRATE\fP Hz
-
-.TP
-\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 infinitely.
-
-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 corresponds 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
-
-.SH AUTHOR
-The speaker-test program was written by James Courtier-Dutton.
-Pink noise support was added by Nathan Hurst.
-Further extensions by Takashi Iwai.
