Hi guys. Andy here - one of the engineers at GenAudio, the creators of the AstoundSound technology.
Charlie, I'm happy to hear that you enjoy what AstoundSound brings to the listening experience. We feel the same way!
We are diligently working on bringing the AstoundSound process into the home listening environment as well as mobile/tablet. While we certainly are a video game product (you will start to see AAA video game titles using the technology very soon), we are also absolutely relevant in both the music and film spaces.
We have an iOS app launching very soon which replaces the need for the iTunes app on your phone/tablet, giving you the same access to your music library as with iTunes, but also adding our advanced audio processing features to enhance the audio for both headphone and speaker listening.
As for film, we have a couple of different implementations of the technology. One for the consumer, and one for the professional film audio industry. For the consumer we have a multichannel to stereo fold-down process that allows us to "virtually localize" the original speaker locations of a multichannel listening environment in a stereo system. This means a 5.1 or 7.1 or x.1 soundtrack can be faithfully recreated over only 2 channels - for headphone and speaker. On the professional end, we are working on a system that is essentially very similar to Dolby Atmos, opening up the sound field to immerse the listener, however we employ digital filters to process the audio and play it back through the existing speaker system rather than adding more speaker/amp hardware as with Atmos.
Finally, we have not been acquired by AMD or any one else. We're still going strong here and doing our best to bring the AstoundSound experience to as many platforms as possible. We thank you for your interest and look forward to the day when everyone can enjoy AstoundSound as much as we do.
