| 20100169102 | LOW COMPLEXITY MPEG ENCODING FOR SURROUND SOUND RECORDINGS - The invention provides for the encoding of surround sound produced by any coincident microphone techniques with coincident-to-virtual microphone signal matrixing. An encoding scheme provides significantly lower computational demand, by deriving the spatial parameters and output downmixes from the coincident microphone array signals and the coincident-to-surround channel-coefficients matrix, instead of the multi-channel signals. | 07-01-2010 |
