I've considered a number of alternatives, finally I consider AudioTester to be the best software for me, followed closely by REW.
The only nag is that AudioTester is not downloadable anymore, but I have it installed on 3 computers, but it may mean that it may not be maintained.
The only remaining issue is finding an adequate soundcard.
The one that looked the most promising, the ICON Cube Pro (192kHz, no knobs) turned out to be a pig in terms of frequency response with about 10dB variations in the passband!
The Behringer UMC202HD does not show anything above 25kHz at 96k SR - it is supposed to operate at 192 but it just doesn't.
So, does anyone can suggest a soundcard that would operate significantly up to 70-80kHz? Calibrated level would be a plus.
