This archive contains two fascinating programs for observing and
measuring frequency structure of audio data.  The first is Version 6.2 of
"Amiga Spectrogram," the ultimate Amiga audio data analyzer.  Produce a
high res color picture of frequency structure of any 8 bit audio data file
with choice of frequency resolution and complete control of color palette.
To have full control over the color palette, you must first copy
color.library to the libs directory of your boot (workbench) disk.  Use the
CLI command "copy color.library to sys:libs".  Complete developer
documentation for color.library is available with the library on Fred Fish
disk #257.  Note that Version 6.2 of "Amiga Spectrogram" corrects earler bug
that prevented using the WB 2.0 ASL file requester).

   The second program is "AudioScope" which provides a real time spectrum
analysis of audio data.  "AudioScope" requires an accelerated Amiga
because of the massive computational load and is designed to work with
the Perfect Sound 3.0 audio digitizer.
