That's not a very simple thing to do, but one goal for RCT 2.0 is to have
Reyburn CyberTuner's Pianalyzer component (specialized piano spectrum
analyzer) save to a standard file format.

Digital audio recording produces massive amounts of data, probably way too
much for a spreadsheet to handle.  That's one of Pianzlyzer's functions,
it
translates the sound into a useable form.  I'm currently working on making
pianalyzer able to give output which would be useful for both rebuilders
and
investigators in examining tone atack and decay.  Willis Snyder (one of
the
best rebulders arround) was in my RCT class at the Wisconson PTG
convention
in April.  He had several sugestions for graphs which I'm working on.

If you want to crunch that much data yourself, and you're not a
programmer,
you might want to look at getting a program like "Mathmatica" which is
available on all platforms.

It could be converted into midi data on the fly, but it would be slightly
behind the beat.  But who ever heard of a tuning device which played
music?

Caution: Shameless plug comming up!

Don't miss Mitch Kiel and my class "The Digital-Aural Tuner" at the
Orlando
Piano Technicians Guild convention this July. We'll be covering some new
ground in this very area!
