Using music or other signals as source for Dual Channel FFT Analysis
I note that the Dual Channel FFT Analyzer will only run when the its own excitation signal generator is enabled. Also, it does not "see" any other signals sent to the selected Output device, not even those generated by FEAT's own Signal Generator. So the only way to measure transfer function is by using the its excitation signals. This seriously limits its functionality for sound system evaluation, which sometimes has to be conducted during actual performances. Is there a method to do this?. Any ideas how to get around this limitation?. It would be nice to be able to measure system response with any excitation source without having to physically patch the computer audio output to an input, thus losing an input channel.
