The aim is to make measurement laboratory, in particular, to measure
distortions of audio amplifier. Using JACK, I can route line ins/outs, find
clean sine signal and get amplified one, and then route last to... Well,
the questions are:
- are there some graphical FFT frontend to see signal harmonics?
- has anybody success experience here?
- are there some caveats and traps in such measurement?
I have 24/96 card (Terrateck Aureon 7.1) with (as I think :-) good
DAC/ADC. So, measurements accuracy may be rather high. Is it so?
