NAME
     xanalyser - a frequence spectrum analyser for X

SYNOPSIS
     xanalyser [options]

DESCRIPTION
     The  program xanalyser reads audio data from the soundcard, performs a fast
     fourier transformation on these data and displays the resulting spectrum in
     a X Window.

     It has no facilities to control the audio mixer. This must be done  by  an-
     other program.

OPTIONS
     -rate int
	     Set the sample rate. The possible values are limited by your sound-
	     card.

     -length int
	     Set  the  length  of each set of sampled data. The length must be a
	     power of two and is limited by your soundsystem.

     -resolution int
	     Set the sample resolution. Must be 16 or 32, but not all values are
	     supported by all sound srivers.

     -device string
	     Sets the audio device. This also  automatically  select  the  sound
	     driver.  Devices names starting with "/dev/" use the OSS driver and
	     names starting with "plughw:" use the ALSA 0.9 driver. Some drivers
	     may not be available on your system.

     -soundcard
	     Select the soundcard as input.

     -diskfile
	     Select a diskfile as input. Use the option filename to specify  the
	     name of the file.

	     44100 Hz and in CDR or WAV format. Note: This  is	mainly	intended
	     for testing.
