*******************************************************************
SVGAFFT spectrum analyzer
for Linux
0.1c alpha
*******************************************************************
This is an alpha release of a spectrum analyzer for Linux. It uses
the /dev/dsp device and currently supports 16-bit and 8-bit sample
resolution on supported Linux soundcards. It's display is something
akin to a high-end spectrum analyzer with falling peaks, however it
does require a fairly high-resource environment and a fast processor
(>=486DX/33). It is currently in development but it is far enough to
be somewhat useable.
*** Needed to run
-----------------
Currently this only runs under Linux I believe, 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.
*** Needed to compile
---------------------
To compile the sources g++ (gcc) is needed along with the SVGAlib
libraries (libvga + libvgagl). If you have kernel older than 1.1.75,
you may have problems compiling due to a missing file. There were
some changes to the include files from the older kernels, so if you
experience a problems you should be able to remove the line containing
the include file directive without any change. Be sure to read the
INSTALL file and also once you get it compiled and working properly
also check out the README in the ./examples directory.
*** Availability
----------------
The archive includes a binary and should be available sometime this
week 1/15/95 on sunsite in the /pub/Linux/apps/sound directory or on
tsx-11.mit.edu in the /pub/linux/ALPHA/svgafft directory.
