For both a speaker and microphone, there are some aspects that cannot be changed with equalization and signal processing. The most predominate is dispersion. This cannot be decoupled from the room though for reproduction, the goal of ATMOS and similar methods is to not only provide a more feature rich reproduction capability, but to dampen the effects of the room. I am a firm believer that even for 2 channel playback, we have not even scratched the surface of what could be done by using more speakers during playback and signal processing.
It is probably people our age dying off or retiring that will bring about some changes in recording. Microphones are picked for their recording pattern and frequency response (tone). There is no reason for the latter any more. It can all be done in post. I remember a presentation on using a microphone array consisting of many microphones with narrower patterns, that were then combined in software. The software could simulate a single microphone of a particular pattern, or provide any number of individual outputs. Is that the future?
In my world, my customers want low distortion, flat on-axis, and smooth predictable off axis, not unlike the Harman research. For recording, mixing, mastering, they can't be second guessing what is in the recording, and what is being enhanced or suppressed due to the playback hardware. For movie/theater sound, they need to know with high confidence how it is going to sound during playback.
For all the bluster in the audiophile community for playback, I do not think we have a good handle on what drives people to prefer X over Y. Hence, while it is useful to discuss sound alteration during playback to suit personal preference, I don't think anyone has a good handle on the controls that would even be offered to the general consumer to provide that tailorable experience. I think this is one place where artificial intelligence will enter our market.
I am sure you are aware there is software to allow studio monitors to simulate other monitors / home systems / cars / etc. We do get customer interest in that area as they assume we could do a better job at it than the present offerings.
