| Abstract: | Stereo recording and editing processing of high-definition television production are introduced.The conversion of stereo channel to 5.1 surround sound by surround sound field synthesizer or multi-purpose audio processor is illustrated in broadcast environment.The choice of stereo microphone in HDTV shootings,the on-the-fly stereo audio monitoring,and the stereo recording level are proposed.The editing and processing of stereo audio lead to a successful conversion of 5.1 surround sound production.Furthermore,a surround sound processor is a shortcut to 5.1 surround production. |
