Before investing into „surround sound installations” I would like to see a solution for inter-channel cancellation of crosstalk and a more sophisticated recording technique. Even the most advanced concepts of wave field synthesis are far from any practical solution! I guess surround sound mandatorily requires the visual input from the cinema screen to create the illusion of surround sound!

When WiSA becomes more popular, multi-channel audio for music, may also become more popular ....... Harman brands, Klipsch, GoldenEar, Polk, B&O and some others are already making WiSA capable speakers ....... May be KR could review some of them? :-) ..........

There already was an existing good solution in UHJ-format.

B-format could have been used for initial recording (tracking) and mixing, and that could have been processed to UHJ-format in the mastering effort for distribution and for consumer playback.

Legacy mono and stereo masters could also be processed to UHJ format.

UHJ has the advantage of being _easily_ scalable both in recordings and in playback.

When DVD was released to the retail market (late 1996 in Japan, early 1997 in US), the standards accommodated more than enough channels and bandwidth for full sphere UHJ.

The mini-DVD form factor was included in the initial release. It had adequate capacity, and the smaller diameter was convenient for carry in a conventional shirt pocket.

Recordings could have been distributed on mini-DVD and UHJ decoders could have been built into the DVD players or outboard processors.
