I wondered if it is possible to get data from the soundcard, process it and then display the result.
For instance, i want to read the input, do a fourier and then display a waterfall-display or amplitude values.
What do you need to do this ?
1. A connection to the soundcard
2. A buffer that contains the read data, size wil be variable (?) whats the format ?
3. A way to convert the incomming data to a usable bin-format so you can do stuff like FFT.
Knowing this is a large undertaking and probably VB is to slow to do this but as far as i know
it has not yet been atempted (cannot find any example or code on the web)?
Now the thing you dont want is first make a .wav file and then read the data from there, it has to
be "real-time" (from a .wav-file is done / code is available on the net).
Who can help ?
