DRA Audio Coding Standard

Abstract:

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 subjective listening tests are presented.
