DSP dirac test error ‘low signal to noise level’
Keep getting this annoying error when I'm doing a measurement. I am using a Umik microphone, calibrated, for dirac. The microphone is connected to a laptop.
It says to reduce background noise, there is none. I reduce the gain and increase the channel volumes and still the error happens.
Anyone else have these annoying problems?
