Hi everybody, thx for the replies.
To measure what’s going on or doing some room correction, I would recommend the following Equipment…
Software: Acourate 2 (FIR) or REW 5.20.8 x64 (IIR)
FIR-filters (Finite impulse response) could be imported into Roon.
REW uses IIR-filters (Infinite impulse response).
Microfone: Behringer ECM8000 (calibrated to 0° and 90° incl. calibration file for Acourate)
Soundcard: Lynx Studio E22 or RME HDSPe AES PCI Express Interface or RME HDSPe AIO Pro (You have to check if these cards are compatible with Acourate 2)
If you want correct timing information in and out should go over the same soundcard.
Greetings
