For two DACs, outputs A1 and A2 would be enabled. If you have Voicemeeter installed, Voicemeeter outputs appear in EQ APO configurator. It doesn't actually work as an APO, it uses Voicemeeter's Audio API instead. Now, using EAPO editor enable EAPO for both devices USB1 and USB2 (this will be after Voicemeeter in the chain).įor the EAPO configuration file, do the eq for each output using the device selector control to separate the settings for each USB out (with both being stereo).Ĭlick to expand.ASIO and exclusive modes can be used if EQ APO is attached as a Voicemeeter plugin. The above is now set up for your use case but without any EQ. You can use ASIO or whatever you want to reach Voicemeeter from foobar. So, it sends the same audio to both devices which lands up in the two different DACs. Under the Voicemeeter main input unable both A and B.

But don't select ASIO driver or any direct mode for this. In Voicemeeter, select one USB out for A and the other for B as outputs. Send foobar output to the Voicemeeter main input device as a stereo device. Just do stereo to the two USB devices and attach EAPO to both the USB devices and configure for each: With Voicemeeter that is essentially what you would do for the cleanest solution. Voicemeeter will be the easiest unless you can find something simpler that can split audio (with no EQ) to two devices simultaneously. Would that work too ? How would my config file look ? (I'm new to Equalizer APO, just installed it a couple days ago to test HeSuVi on a single pair of headphones - it works great BTW, some presets are pretty convincing ) Ch3-4 : Equalizer APO preset 2 + HeSuVi preset 2.Ch1-2 : Equalizer APO preset 1 + HeSuVi preset 1.Voicemeeter would then process the non-EQed 4-ch signal as follows : Since HeSuVi is itself a plugin of EQ APO, I suppose that's possible by configuring EQ APO accordingly ? That means applying a HeSuVi preset to ch1-2, and a different HeSuVi preset to ch3-4. My final goal would be to insert HeSuVi into my config, for each individual headphone. Would that work ? Which solution would be best ? I would love solution 1 if that were possible, to get rid of ASIO4ALL. Solution 2 : Voicemeeter outputs all 4 channels to ASIO4ALL which does the splitting.


I guess that woud be easy : foobar would output a non-EQed 4-ch signal, Equalizer APO would equalize ch1-2 with preset 1 (for headphone 1), ch3-4 with preset 2 (for headphone 2), and then it would output an EQed 4-ch signal.īut I'd still need to communicate with my two DACs simultaneously, and AFAIK an APO can't do that.

I would now like to use Equalizer APO instead of foobar for the equalizer part. This setup already works perfectly, with no sync issues at all despite what some people said.
