I use asioforall and choose for input my behringer USB soundbox which support 48 Volt phantompower. for output i use my sounblaster z soundcard(which i use normaly) which is connect with digital out to my surround receiver. i disable EQ in surround receiver and i measure. the curve look very strange. the after curve show above 2 khz -10 db upto 20 khz. i have mems microphone. and all tests work ok. the low freq upto 2 khz seem correct measure. but above 2 khz is boost alot and so sound very thin and bright
when i use the analog out of my USB soundbox, i hear noise depend on computer action. so i use this normaly not.
is it possible in ARC to measure with diffrent in and out sound devices or not ?. it is hard for me to get the analog out working from the USB soundbox
