Microphone Front-Ends for Spatial Audio Coders

Document Thumbnail

Spatial audio coders, such as MPEG Surround, have enabled low bitrate and stereo backwards compatible coding of multi-channel surround audio. Directional audio coding (DirAC) can be viewed as spatial audio coding designed around specific microphone front-ends. DirAC is based on B-format spatial sound analysis and has no direct stereo backwards compatibility. We are presenting a number of two capsule based stereo compatible microphone front-ends and corresponding spatial audio coder modifications which enable the use of spatial audio coders to directly capture and code surround sound.
