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
       another program.

	       Set the sample rate. The	possible values	are  limited  by  your
	       soundcard.

       -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

	       Selects the file	to play. The file must be 2 channels, 16 bits,
	       44100 Hz	and in CDR or WAV format. Note:	 This  is  mainly  in-
