I just got my first Metric Halo interface: LIO 8 and working on setting it up for use with POST and MUSIC mixing in HT ATMOS (BOTH BASS MANAGED AND FULL RANGE), 5.1, and Stereo. I want to accomplish 2 things with the DSP graphs:
1- Fold down ATMOS 7.1.4 to 5.1.2 (since format not supported by Dolby DAPS or Metric Halo)
2- Perform room correction (eq, delay, phase correction)

1- The fold down is pretty straight forward just emulate what downmixer plugin would do going from 7.1 to 5.1 .. Fold side surrounds into rear surrounds @-3db, and then fold rear tops into front tops @-3db. I think this is the best way to do it but let me know if someone has a better idea. I used volume control linear with -3db setting.

2- Room correction: complicated topic and I've never calibrated an ATMOS room before so not sure if my chosen DSP signal flow and chosen tools are the best way to do it. Please help me understand what could be better about this design:

SIGNAL FLOW- PT host outputs 7.1 beds + objects > Dolby DAPS 7.1.4 > MH MC source 7.1.4 > MC output graph folds 7.1.4 to 5.1.2 > DSP GRAPHS ROOM CORRECTION > ANALOG OUT TO SPEAKERS

ROOM CORRECTION SIGNAL FLOW IS: INPUT > BAND SPLIT > EQ CORRECTION VIA SONIC EQ > PHASE CORRECTION VIA MIO ALLPASS VD, SPEAKER DELAY CORRECTION VIA MIO DELAY (1K)

ATTCHED IS A SCREEN SHOT OF MY MONITOR GRAPH
