Does anyone know how to display *.wav files graphically as they are recorded?

Does anyone know how to display *.wav files graphically as they are recorded? Example I'm creating a *.wav file, but I want to be able to view the *.wav file graphically as it is recorded by the computer.

What form? Spectrum display or CRO style?

For the spectrum display, you'd need to use the FFT functions (don't even think about doing that in VB) to convert the data from the time domain to the frequency domain. That is, the sound is stored as amplitude against time. FFT converts it into freqency/amplitude against time. This way you can see which frequencies are the strongest (perhaps this will be of use to your other thread).

Ok, don't use VB. But I have already vested years of development to this project in VB. It's not that simple. But could you send me the coding for this feature in whatever language, and I will have to create a C++ *.DLL, class, module, or something.

I don't know how to do it, but do a search on PSC or AltaVista for "Fast Fourier Transform" and you should get something worthwhile. I did see some code in C a while back, though, so it's obviously floating around there somewhere.
