Don't laugh, but in the dark ages, I had to write Fortran programs to
do such calculations.Matlab didn't exist. Hey, I said stop laughing!
;-)

I recently took a tour of the NSA museum, and they had a computer punch
card on display. Well, I suppose there are people who never saw one,
but geez....

Interesting. Is there a canned program to take an autocorrelation of a
wav file?

I use Matlab. It is a general purpose math tool. A lot of
people use it to prototype DSP algorithms. There is
a student version for $150. It is good enough.
There is also an open source, free program called Octave
that tries to be compatible with Matlab. Matlab programs
can generally be ported to Octave with more or less work.

Snip

They just got through trying to hit me up for $1000 - $1300 bucks for
versions 12 and 13.

Yeouch. At prices like that they are begging for
competition.
That makes me wonder what we are
paying for it at work.

I know a few young engineering students who have the
full version. I suspect they obtained it through...
alternative sources.
