When transmitting high-quality audio over a wireless link, it is often beneficial to code the audio signal in order to occupy less radio spectrum. Therefore, RTX has developed Sheersound, a supreme and unique audio codec (Coder/Decoder). It is specifically designed for wireless transfer of live audio signals with extremely low latency and highest possible audio quality. The codec provides excellent audio compression with 20 µs latency with full Hi-Fi bandwidths and beyond. Sheersound is available on a range of DSP architectures from leading IC providers and is a perfect match with wireless radios due to built-in error resilience.
