Low-delay audio coding is a somewhat new trend in perceptual wide-band audio coding. Low-coding delay is important, for example, in applications based on bidirectional real-time audio transmission. The technical aspects and psychoacoustics of such applications are reviewed, and an audio codec with a coding delay of less that 2 ms is introduced.
