The Importance of Audio Live Panel
summary
Panelists describe concrete advances: an open source C++ Lyra codec that runs in real time on midrange phones, Lyra 3 kbps ≈ Opus 8, and a new Soundstream engine that uses residual vector quantization and scales bitrate with Soundstream 3 kbps ≈ Opus 12. They report integrating denoising into codecs, work on adaptive bitrate for Atmos and spatial audio to headphones, emphasize loudness normalization, and warn that cheap ML codecs must remain runnable on older devices to avoid fragmenting the user base.
