I have no problems utilizing equalizer APO/peace GUI with the computer as the source......to one or one pair of speakers only
What I would like to do with my current set up: (please let me know if this is possible.....so far I have failed.....also let me know if there is a work around......don't mind buying another low cost preamp and/or DAC if necessary)
TV as the source.....in this one room, I enjoy utilizing the TV as the source as I do a lot of over the air antenna TV watching (uncompressed video and audio) and like the TV Spotify interface......and watch a lot of Blu Ray movies (Blu Ray player to TV with HDMI)
With my current set up I have the TV going to an amplifier with High pass and full range out. The high pass goes to a pair of DIY exciter panels. The full range out is split to a subwoofer amp with low pass for the subwoofer and the other split off RCA full range goes to another amplifier to drive a DIY mono full range center speaker.
I would like to place the computer (in line) in front of the amplifier that drives the DIY mono full range center speaker......to room correct that speaker with a PEQdb filter uploaded to APO equalizer on the computer to filter and room correct that center speaker only.
Is this possible?
Thank you.

What I have tried
Line level in to the computer's 3.5mm aux jack and then a USB-C to 3.5mm for the audio out.
I tried with TRS and failed. Ordered some TRS female to TRRS male adapters to see if this solves the problem.
I also ordered a HDMI to 3.5mm to try utilizing the HDMI port for audio in and/or audio out.
Also thought of buying one of those TRRS splitters (one for headphone and one for microphone)....then just plug that into the computers 3.5mm aux to see if that would work.

I do have an extra Ear Studio ES100 portable DAC.....thought about utilizing that for USB-A audio out to the amplifier set up in mono for the DIY mono center channel speaker.
Suppose I could also split the Audio out signal at the source (the TV).....the simplest way would be to split the aux out at the TV.....with the first split going to the HPF amplifier and the other split going to the Aux in on the computer....but this is essentially what I'm already trying (just splitting the full range signal farther downstream with my current attempts)
I may have discovered a solution utilizing a Qudelix 5K (of which I have two already)
1. use the computer as the source to room correct via APO and PEQdb.
2. Upload the the PEQdb generated filter to a Qudelix 5K via the Qudelix chrome extension
3. Place the Qudelix 5K inline with RCA to USB into the Qudelix 5K in front of the amplifier that drives the mono center channel speaker
4. then 3.5mm out from the Qudelix 5K into the the amplifier that drives the mono center channel speaker with a 3.5mm to RCA adapter.
This solution might work (with the Qudelix 5K on battery power)......would just have to recharge the Qudelix every now and then.
......I'll control the Qudelix 5K from the phone app and select the generated PEQdb filter.
^^^^^ I believe this has the greatest potential for success and would eliminate the need for the computer to be in the audio chain (removes potential ground loop problems, and allows greater freedom to use the computer for actual work)

Will probably require a RCA in to USB out interface in front of the Qudelix to convert analog to digital in front of the Qudelix.
ART USB phono plus or similar might work…with a USB-B male to USB-C female adapter.

Found one of these for $65 on Amazon. I’ll connect it inline with USB-C to a Qudelix 5K with an uploaded room correction file. Then 3.5mm to RCA from the Qudelix to the center channel amp. I’ll update if any of this works or not.
Didn’t work.
Measuring and calibrating the DIY speaker utilizing the computer as the source in room at the listening position; then uploading the PEQdb generated filter to adjust in room response to a Qudelix 5K, then applying the filter through Qudelix out from the computer as the source and listening to the applied filter was straight forward…..but only with the computer as the source.
I was hopeful that RCA line in to the USB interface preamp then USB out to Qudelix then headphone out from the Qudelix to RCA adapter into the DIY speaker amp would work seamlessly; but it didn’t. The Qudelix did not recognize the USB out from the Dynasty ProAudio USB interface.
I do have the generated parametric EQ setting quantifiers; so I could place an inline DSP and just manually enter in the numbers.

Yes, it is possible. You can route the TV audio to your computer, use Equalizer APO/Peace GUI to process and room-correct only the center speaker, and then send the corrected signal to the amplifier driving that speaker. You may need an additional preamp or DAC to split the audio and route only the center speaker's signal through the computer for EQ processing.
