AES Convention 119 · Paper 6601 · October 2005

Abstract

Low latency audio coding gains increasing importance among upcoming high quality communication applications like videoconferencing and VoIP. This paper provides a comparison of two low latency audio codecs suitable for these tasks: MPEG 4 ER AAC-LD and ITU-T G722.1 Annex C. Despite their similar coding strategies both codecs show significant differences with respect to the used tools and coding performance. A comparison of the coding tools is provided and the influence on different signal classes is discussed.
