Anyone knows a software to use with soundcard for signal sine wave generator, with dBu scale readings?
I am looking for something for calibrating compressors.
Especially with GSSL I would like to do the ratio calibration, for this I need to send a sine wave to the compressor and reading back the return. I can't do it with the normal DAW signal generator, wich obviously works in dbFS, because I want the calibration in the analog domain.
I know that there are hardware machines for such measurements, but I suppose very expensive, so a software solution would be better.
