Dolby Labs Introduces AC-4: 5.1 and Atmos Surround at Lower Bit Rates

[bmoura]

Dolby Labs has introduced their newest audio coding system: AC-4.

It offers 5.1 and Atmos Surround Sound for TV and other applications at data rates a fraction of those used by AC-3 and Dolby Digital.
5.1 Surround Sound can be transmitted with only 96kbps rather than 384kbps required for AC-3.

Hopefully this will be a step forward to being able to stream Multichannel audio. I'd love it if we could have access to an online 4.0/5.0/5.1 Classical music radio station. I'd also love to post Quad Youtube videos.
