I have a rather unique setup compared to most Hey! so i've been a lurker here for some time, and too have found sanctuary in REW/EAPO but have had minimal success pulling off convolution successfully. I'm starting this thread to see what kinds of projects you all have going on using any of these amazing tools. One of the best things about Equalizer APO's convolver is that it's suprisingly low latency. Rephase allows you to correct phase blind by inputting the crossover topology. This system is superior to a lot of pro tools like Diraclive because for one thing, dirac live is practically useless for phase correction because you can only get accurate phase data at close range with lower volume levels. You can repeat that enough times to make your frequency response look unbelievably smooth. You can then remeasure that channel, create another filter to fine tune the response and load that into the next bank in rephase to make a more refined impulse file. Save the impulse as a mono WAV and select that as the convolution filter in Equalizer APO and WHAM you've got an active crossover, linear phase system. In rephase you can also correct the phase and set up crossovers for each channel. Then open rephase, import the measurement from REW and the filter settings. Then you can use REW to dial in the exact FR that you want and save those filter settings to a file. Using Equalizer APO, you can copy the L and R channel to other outputs on an 8 channel sound card. I would like to offer help to anyone who would like to learn how to make use of these tools because all of them are free and they can replace a lot of very expensive hardware. I've been working on calibrating audio systems for so long and now this combination is truly something special to me.
