Preference/Freature request: 1.5kHz or 750Hz test tone for soundcard calibration at 48kHz, 96kHz or 192kHz samplerates

[daihedz]

Hi... and hopefully I am right at this place with this kind of input:
I was wondering why calibrations/measuring the soundcard is hard-coded to 1kHz in case of samplerates of 48kHz, 96kHz and 192kHz? FFT/Display might be easyer/cleaner for a frequency of 750Hz or 1.5kHz - e.g. 96000:1500=64. So e.g. for inside the peferences and for the soundcard tab: Why not allowing for a user-defined frequency for the soundcard calibration's process (I would set it to 1.5kHz) ? The default 1kHz value could still remain as the historically grown, but digitally marginally weird 1kHz.
Regards Daihedz

The tone is just a level check before the calibration, which uses a full range sweep.

FFT/Display might be easyer/cleaner for a frequency of 750Hz or 1.5kHz - e.g. 96000:1500=64.

How would it be better than 96000:1000=96?
1kHz is a historical reference in frequency response measurements.
