I make no promises that this code will do what you want or even that it
will do what I meant it to do.  You use it at your own risk.

(Formerly Deeth Spectrum Analyzer)


[About]
It's a simple audio spectrum analyzer.  It opens a waveform audio input device
for 16-bit mono input, gets chunks of audio, runs the FFT on them, and displays
the output in a little window.

The Visual Basic sourcecode is included.  It demonstrates an easy and fairly
fast way to do graphics double-buffering with a hidden picturebox, audio input,
FFT usage, etc., etc.


[New in version 2.0]
New version has better coding style, bugs fixed, output improved (true
spectra power calculated, better scaling, Blackman window applied), is
resizable, is probably faster (the FFT certainly is), uses a double
buffer for the audio input (less waiting), has generally better code,
and it's now very easy to adjust the sample chunk size and the sample
rate.


[Aknowledgments]
Once again, thanks go to Don Cross for providing the original FFT code.


[Requirements]
You will need the VB6 runtimes for this to work.  You can get them from:
ftp://ftp.microsoft.com/Softlib/MSLFILES/VBRUN60.EXE

And a soundcard, of course.
