        SVGAFFT signal analyzer 
	for Linux

	0.2c alpha

*******************************************************************

See CHANGES for the change log.
See INSTALL for installation instructions.
See README for some useless information.


This is an alpha release of a realtime signal analyzer for Linux.  It
uses the /dev/dsp device and currently supports 16-bit and 8-bit
sample resolution on supported Linux soundcards.

What is being developed is what will hopefully eventually be a package
designed for visualization of fourier coefficient data and further
down the line a method of editing data for playback.

SVGAFFT requires a high-resource environment and a fast processor
(>=486DX/33).  It is currently in development but it is far enough to
be somewhat useable.  Eventually there will be more optimization
including processor-specific assembler.


*** Needed to run 
-----------------
Currently this only runs under Linux, but eventually an X Windows
version should be available that is more portable.  The binary
requires svgalib [and a compatible card], a Linux sound driver
compatible card with a valid dsp device, a math-coprocessor
(preferably a 486DX/33 or higher), and a low-load machine. Portability
currenty prevents a high degree of optimization, but other options may
pursued in the future to improve performance.  Kernels of 1.2.0 and
over have been tested.  Some DMA problems have been reported with
earlier kernels.


*** Needed to compile
---------------------
To compile the sources g++ 2.6.3 (gcc) is needed along with f77,
SVGAlib libraries (libvga + libvgagl) and version 1.2.x of the kernel.
If you have kernel older than 1.2.0, well, it's about time you upgrade
;-).


*** Availability
----------------
The archive includes a binary and should be available sometime this
week 5/2/95 on sunsite in the /pub/Linux/apps/sound directory or on
tsx-11.mit.edu in the /pub/linux/ALPHA/svgafft directory.


*** Copyrights & Disclaimers 
----------------------------
Everything but the FFTs are under GPL copyright by the author.
MAKE SURE YOU HAVE 0.2c, since the older versions the FFTS
have changed!!!
