With modification of those software capture routines, Audyssey could enhance it's MultEQ package offering to assist customers in determining Subwoofer(s) and Main RH/LH speaker optimized location.
Proposal itself is shown visually in the 2 pictures attached.
Knowing that for best audio/sound in a listening room, these parameters are tackled in prioritized order:
1. Speaker location, 2. Listener position, 3. Acoustic treatments, 4. Electronic correction.
Audyssey technology can be utilized for optimizing 1 and possibly 2, in addition to 4 as currently done.
On the surface, the subwoofer seems the leading candidate for this proposal, as most people's sub(s) can be changed location relatively easily.
A shift of say 6 - 12 can affect the peak/null at the Master Listening Position (MLP), so this can do the reverse of the subwoofer crawl, capturing objective data and using that to assist in optimal placement from a MLP.
>>This will also work for multiple subs, each optimized for its location relative to same MLP.
The Mains RH/LH, that location mostly is dictated within a tight envelope of front/side walls and display device, etc.
However, still opportunity for optimum placement could be identified using the same basic routines, changing the judgment criteria for Main speakers instead of subwoofer speaker(s).
(ie SBIR minimized, etc).
This proposal is the KISS concept, Keep It Short and Simple.
Baseline position plus up to (2) alternative positions would be measured from just the MLP, and then data analysis done, then visual ranking by simple #1, #2, #3.
An optional visual graph overlay of the Freq response plot/other chart would be made available.
This is a high level proposal, details of course underline it and need further discussion, but this post intent is to get the concept out.
The marketing of this seems to fit with the MultEQ XT32 customer in mind, being those customers are more tweaker orientated and will want this.
The above dealt mainly with determining 1. , speaker position.
