DRA Audio Coding Standard

摘要：

　　Chinas DRA audio coding standard is shown to be a barebone transform coder,utilizing transient-localized MDCT for improved pre-echo suppression and statistic allocation of codebooks for high entropy coding efficiency.A signal path of up to 24 bits is provided throughout the codec so that highest audio quality can be delivered if bit rate suffices.Results of five ITU-R BS.1116 compliant subiective listening tests are presented.
