OVERVIEW
---------

This is an alpha version of a signal analyzer for the Linux operating
system. It is not complete and is actually not very accurate yet, but
it is good enough for alpha ;-).

It requires the use of a Linux kernel above version 1.2.x and SVGAlib
1.2.4 or higher.  Also since this is alpha, some of the documentation
is probably outdated.

NOTE: Although this is under GNU GPL, please do not upload modified
versions of it bearing the same name.  This is under constant
development, so if you have a suggestion, email me and I will consider
it in a future version.

To use it, you need a sound card supported by the Linux sound driver.
An 8-bit card will work, but not by default.  To use the program for
an 8-bit soundcard, use the -8bit command-line option.  If you have a
16-bit soundcard, you can toggle between 8-bit and 16-bit modes by
pressing the `b' key when running the program .  Anytime during the
display you can hit the `?'  key to obtain a keyboard help screen.
16-bit cards also usually have a much better frequency response even
in 8-bit mode.  You also need a fast card compatible with svgalib, not
to mention a fairly speedy computer (486dx2-66s and up work best).
Eventually, optimized assembler fft routines will be included.

See the `examples' directory for some sample configuration files and
the `analyze' script which makes repeated configuration much easier.

Please be sure to read the manpage...
