You are right it is not possible to use Touch to play the Audiolense signals! There is a touch plug-in called Waveout which permits that but it doesnt work if Inguz is installed, they are incompatible! Im using a Maudio external Firewire card. I send spdif signal to the dac and record it with the Maudio card. Yes Touch is not in the measured chain but it still gives very good results with Audiolense. What is important is that the speakers are equidistant from the mike (Audiolense gives you the delay between channels and this delay has to be very small, something like 0.02ms) Ideally to get the best results from DRC the room has to be acoustically treated and speaker at least roughly time aligned (if actively crossed). The results are spectacular! DRC corrects amplitude, phase and time alignment although only for the measured position. Chris PS duplex card is not a must but the signal must be generated by the analysing software (Audiolense) in order to build the impulse response. Theoretically Audiolense can accept imported files but I didn't succeed to make it work, i.e. to record trough Touch with Audacity for example. -- krzys ------------------------------------------------------------------------ krzys's Profile: http://forums.slimdevices.com/member.php?userid=2256 View this thread: http://forums.slimdevices.com/showthread.php?t=93393
