A surround sound processing arrangement where directionally encoded audio signals in a B-format (W, X, Y, Z) or B-format-like signals are via a primary matrix, synthesizing virtual arbitrary microphones, encoded to intermediate channels used as virtual loudspeaker feeds. These virtual loudspeaker feeds are via a secondary matrix transcoded to multiple channels corresponding to coincident or non-coincident virtual arbitrary microphone signals suitable for subsequent mono, stereo or surround sound loudspeaker replay. The described transcoding process enables variation of the properties of the reproduced sound field regarding parameters such as localization, depth, image size, spaciousness, envelopment, and particularly can offer a stable frontal image and a large listening area size. |
