摘要：

WEG-4 AA C audio encoder is developed. AA C main and AA C Low Complexity object types, defined as part of Main profile in General Audio part of ISO/IEC 14496-3 (MPEG-4) standard, are implemented Encoder targets high-quality, wideband, complex audio. Encoder was carefully designed to respect present accomplishments in audio coding (standardized in WEG-4). At the same time, several implementation novelties were introduced Encoder achieves 'perceptible but not annoying' 44.1 kHz audio quality at bitrate 64 kb/s/ch, while satisfying quality is accomplished at 48 kb/s/ch.
