Despite advances in voice and data communications in other domains, sound production for live events still largely depends on spectrum-inefficient forms of analog wireless microphone technology. In these live scenarios, low-latency transmission of high-quality audio is mission critical. This paper examines the key performance aspects of low bit rate audio codecs for the next generation of bandwidth-efficient digital wireless microphone systems that meet the future needs of live events.
