This thread is mostly directed at @OCA to continue YouTube comment section discussions in a little easier format, but maybe it will be helpful to others.
First system I'm working on is my office desktop setup, in a carpeted bedroom that's approximately 4.7m x 4.1m x 2.9m. I live just under 2000m elevation. No acoustic treatment other than a few piles of random stuff in the room (still moving into new house and need more storage space!). Basic rectangular prism with one small closet, leaving the door open for listening is my only "room treatment." Eventually I'll have maybe a couple bookcases and some other objects, but I thought for convenience/comfort of working on this at my normal desk and for the challenge of applying room correction to a fairly "lively" room with moderately non-ideal setup/layout, this would be a good place to start learning practical application of DSP/room correction.
My desk is a large L-shape, simple table-style, no hutches or anything. It's pushed into a corner, and I sit facing the long wall of the room, so my head is about 1.6m from the left wall and 1.4m from the front wall. Two 32" computer screens in front of me, with main speakers nearly touching the edges of the screens and tweeters about ear height. Speaker baffles are slightly closer to me than the screens.
Equipment: Windows PC, USB DAC (Focusrite 2i2), balanced outputs to JBL LSR310s, balanced outputs from sub to JBL 306p MkII, toed in to point directly at listening position. Using CamillaDSP with web-based GUI on the Windows PC for applying filters (VB-Audio Virtual Cable serves as input to Camilla). Measurement mic is UMIK-1.
I followed this video by OCA and due to the 40Hz peak I did not apply EQ above 80Hz. REW files are attached showing before and after left and right measurements (each is a vector average of 2 positions with 2-3 measurements each), and vector average of left and right.
EQ was highly effective (again, only applied below ~80Hz). I used a target curve that was quite a bit flatter than Harman in that region.
Group delay improved:
Impulse response improved a bit:
Clarity improved in the bass region, not sure about higher frequencies difference, but I only applied crossover correction there (1425Hz 24dB/octave):
The really impressive (and seemed audibly apparent) improvement was step response, shown zoomed out and then zoomed in:
At this point I'm going to re-do everything using a higher limit for the EQ to deal with my 100Hz-140Hz plateau, and with the Harman curve as target to get the bass a little more in line with my tastes.
