Can Ambisonics reproduce Dolby Surround AC-3?
Ambisonics cannot contribute to the Dolby Surround AC-3 encoding or decoding processes; it can make contributions before the 5.1 discrete channels are encoded and after they are decoded. Dolby Surround AC-3 is described in technical publications available on the Dolby Laboratories Inc Web page. These suggest that: AC-3 is a digital encoding technique that exploits “audio masking” to achieve high bit-rate reductions. AC-3 can be used to encode between 1 and 5.1 audio channels. Dolby Stereo Digital film sound format uses AC-3 to encode 5.1 audio channels onto film stock. The 5 channels, left, centre, right, right surround and left surround, are all full bandwidth. The .1 channel is a band limited (20 Hz to 120 Hz) bass effects channel. Dolby Surround AC-3, also called Dolby Surround Digital, is the consumer equivalent of Dolby Stereo Digital film sound and is also based on AC-3 coding of 5.1 channels. Dolby Surround AC-3 does not use matrixing and the 5.1 audio channels have complete sep
