| Summary: | Dolby Surround technology offers consumers surround sound in their home via a 4:2:4 encode/decode matrix. Although originally intended for audio accompanying visual media, the system has potential as a music-only playback system. === The purpose of the thesis is to investigate this potential, particularly as it applies to acoustic music recording. Dolby Surround encode and decode technology and its relevance to acoustic music reproduction is reviewed. The classic stereo microphone techniques are discussed with particular attention paid to each one's theoretical ability to "encode" information for the Dolby Surround decoder. Practical limitations and benefits of these well-known methods are considered. === Recently proposed microphone techniques are reviewed in theory and in practice and are found to provide many solutions. Methods for optimizing the decoder technology for music reproduction are suggested. The paper is relevant to any acoustic recording application for a number of surround systems as well as for conventional stereo and mono. |
