What's a good reasonably priced sound card that would be good for doing
guitar waterfall, slab plots and FFTs and what software should I
consider? Is there any good freeware or shareware?
tnx

If your system board is only 1-3 years old, the audio interface that is
built on it, makes a good starting point.

Pardon my ignorance, but what is a"slab plot"? It sounds
architectural.

Well, if you go to this site, you may find something interesting about
all that you are looking for.
This is a little bit much, . . But hey, with THX certification, it
is going to give you a punch.

Slab plots may not be the best term and it may be stack plots. Lets say
you have a plot of wave at time=o and another time=1 and so on. If you
stack these plots offset a bit using a transparent medium you can see
the wave as it decays over time. There's a good picture of this in the
Hewlett Packard catalog in the description of the HP 3561A. The folders
of Microsofts new Vista screen are a step in that direction.

Can't help you with the slab plots or waterfalls,
but my Daqarta shareware has color spectrograms,
as well as spectra and waveform displays, signal
averaging, signal generation, etc.

FFT size is 1024 points, so you won't be able to use
this for tuning your guitar, if that's what you had in mind.
I'm in the process of adding a high-resolution
FFT peak position interpolator that might or might not
help that... it won't separate close peaks, though.

I'd be glad to answer any questions.

Best regards,

I sent an eamil to your site and asked them to send it to you becasue I
couldn't figure your address.

Hi Bob,

Why not? 1024 points (bins) has enough resolution to shake out every
note on a Hawaiian slide guitar. The only care is selecting the
sampling rate and most FFT packages should be able to resolve
exceedingly fine.

There's a good example of a 3D plot he

Has anyone used this software?
tnx
