11.1 processing

The Auro 11.1 technological suite contains all the necessary tools to create content in 3D sound. The Auro-codec offers bandwith reduction by creative mixing and unmixing of multiple channels while remaining in the uncompressed PCM domain. Auro 11.1 is backwards compatible with surround 5.1 and 7.1 thanks to the Auro-codec.

Auro 11.1 decoder

The Auro 11.1 decoder is a 100% firmware based solution that is compatible with the most commonly used media block technologies on the market today. Once loaded onto the media block, the Auro 11.1 decoder is only activated when an Auro 11.1 code stream is present on the audio tracks of a DCP. If this is the case, the media block will automatically route the appropriate channels to the correct AES outputs to be sent to the audio processor. If a given DCP does not contain Auro 11.1 metadata, the media block will simply play back the standard 5.1 tracks.

Auro 11.1 audio processor

The Auro 11.1 audio processor makes it possible to seamlessly switch from normal 5.1 playback to the Auro 11.1 format, either automatically or at the push of a button. The audio processor is a co-development with existing industry leading providers of cinema audio processing technology. Due to the channel count and critical time alignment functions required for the calibrated playback of Auro 11.1, existing audio processors and B-chain equipment are not compatible. The Auro 11.1 audio processor supports all existing interfaces required for a modern Digital Cinema B-chain, including 16 channels of AES inputs, non sync and Ethernet based audio.

Auro 11.1 upmix processor

The Auro 11.1 upmix processor receives any audio source that has been identified by the user for upmixing to the Auro 11.1 format via a network audio interface from the main processor. With capabilities ranging from upmixing a mono input all the way to 13.1 or simply adding a 11.1 to a 5.1 track, the upmix engine has the subtlety and control to turn any audio source into a 3D audio experience.
