W5 - Auro 3D—High Quality and Low Latency PCM Encoding and Data Reduction

Wilfried Van Baelen, Galaxy Studios - Belgium

Auro-3D is first and foremost a family of surround formats including height information, starting with 4 overhead channels (and loudspeakers) and leading up to 13.1. The obvious use for such enlarged arrays is in the cinema, but the 9.1 Auro-3D solution is also applicable to the home theater, as the additional speakers are exactly above the existing ones (L+R front, L+R surround). Besides being a family of formats, also a codec has been developed that can fold down 9.1 to 5.1 or 5.1 eo 2.0 purely in the PCM domain, with ultra-low latency decoding (1ms). The man behind Auro-3D, Wilfried Van Baelen from Galaxy Studios in Belgium, will give an introduction to the Auro-3D codec, talk about latest developments, and play some examples using the codec.
