As it is right now I use a 30 sec sweep. But If I record on tape and can
analyze the recording with a software, why should 1 sec be too short?
Dan, anybody - what is a FFT-meter? It's with my editing program also with
Cool Edit, I think. It looks like a frequency curve and it seems to work as
a such. If I record a logarithmic sweep 20-20.000 Hz in one second, then
make a .wav file of it and ask the FFT analyzer display it - will it show a
common frequency curve, as we know them from before computers?
If so, I can make a "print screen" into Photoshop and print it from there.
Klas.
