Then if Multitone had a control labeled process gain, I could tell it to dial down the results shown by 24 db. Which would be the accurate output of the DAC or other DUT.

So is this something anyone else might find useful, and the big question, is it a big deal for Paul to add in this additional control?

You can do that with a bit of work by setting up a calibration file in MT. All you need to do is specify the range and the dB to scale by. Something like this would do it for 20-22050 range (the last number on both lines is phase):

20 24 0
22050 24 0

The preview results measurements window says L channel on output no matter what you choose.
@Rantapossu keep the score!

It says the same in every out.L,L/R or R.

Measurements show only input channels
And why it reports the out too?
It should be blanc then.Wasn't like this until yesterday.
To be exact,I'm talking about the one I yellowed.

Okay that would work. I hadn't really done anything with the calibration feature.

Having an issue that if a calibration file is loaded, the software just hangs on processing after the measurement.

Post the calibration file, please.

Just figured it out: calibration file causes an error unless you have two channel recording. Fixed it here:

You'll need to uninstall the previous version of Multitone, then reinstall it from the link above. Let me know if this works -- I broke this yesterday, apparently, when fixing other calibration issues.

Is there a way to tell which was the recording channel when comparing the measurements?

It doesn't say it on the title and it doesn't fit on the "Sample Rate" -box. Changing the "Chn" -selector doesn't help either, this is recorded with the right channel and it shows the result anyway even if I choose the left channel from the "Chn" -selector:

Like I said before, knowing the record channel doesn't matter for example with the Cosmos ADC or RME interfaces ets, but some cheaper cards like my E-MU it does matter:

Expand the column width, you'll see the recording sampling rate and channel(s) selected.

Oh, I tried to expand it before and it didn't work... :facepalm:

I was trying it within the white result text area, but now I know it expands only within the blue title area!

Thanks!
