Auro have launched the Auro-CX, a scalable next generation audio codec with channel count and sample rate included in one bitstream.
The Auro-CX Codec is designed for streaming but has applications in broadcast. Its main differentiator over other codec’s is its inherent scalability, which means less storage space and fewer encoding passes, which aim to save time, manpower, and costs.
The Auro-CX enables scalable quality, meaning a variety of resolution are included within a single bitstream thanks to multiple audio waveform coding techniques. Similarly, Auro-CX has scalable sample rates that allow a single bitstream to carry 48, 96, and 192kHz, giving the decoder the option to extract only what it needs from a single encode, depending on its capabilities.
In addition, Auro-CX supports a wide range of flexible broadcast features such as dialogue enhancement and localised audio for multiple languages. It also enables interactive and assistive audio, where the quality of the immersive experience can be set higher than the additional audio tracks.
