    Wow! Ambisonics. Now that’s a name I haven’t heard in a long time! I’ve wondered on a few occasions if Atmos or Aura3D took any cues from Ambisonics technology of if it is completely different stuff.

    • Not really, different technologies. The Atomos system uses object based audio. Ambisonics uses an array of microphones that can be combined and adjusted to produce compelling soundfields.

  • Just fine for theater sound I guess, but why is there always a bunch of competing formats whenever something new comes out?
    As for home systems, forgetaboutit. When are they going to learn that the average home theater buyer has neither the room, $, desire, wife acceptance, etc,,etc, for any of these systems beyond the 5.1s they struggled to get up and running for all the reasons listed earlier.
    Is it all about the money or are the designers and manufacturers honest in their belief that the market really needs and wants this huge expansion of their home technology.
    I guess I’m just mentally blocked that their is enough people with the desire and means to support 9.2 channels in Lord knows how many different formats for a SOTA Home Theater.
    I apologize, guess its just me, I can’t understand how today’s High End Audio stereo market is able to keep itself afloat when I look at the cost of a complete Stereophile Class A system? It could easily swallow up half a million and that’s just for 2 channel stereo. My head spins.
    God Bless Everyone and enjoy your prosperity.

    I have yet to year Atmos at a commercial theater as there are no commercial theaters in the Philly market. I have attended a private demo given by Dolby in NYC and have heard a couple Atmos discs at a friend’s home who is a reviewer. It is definitely a worthwhile upgrade. However, it seems to me that it is best suited to action movies although it can work wonders with music recorded in a large space. The real key to immersive sound and Atmos in particular is the upmixer for use with non encoded Atmos mixes. I have heard it take a 2 channel recording with a ton of the room audible and totally surround you with the room, giving the illusion of being in a room with a 20 foot ceiling. However, you will need a new AVR or pre/pro, maybe another amp, possibly in ceiling speakers, etc. While I am interested, I am waiting for the 4K standards to be set and implemented in both the hardware and software before spedning money on immersive audio. I do look forward to it though. Maybe by the end of 2016.
