AOM is also working on OAC, the successor to the #Opus audio codec. I'm surprised for a few reasons: 1. Didn't feel like there was any room to grow. AAC is transparent at 192k if not lower. Opus is great at 96k and hopefully transparent at some point (128k?). 2. Opus has been around over a decade yet still feels like it hasn't had its moment. It's used in the background a lot (even at Netflix and Spotify?) but I always hesitate to share Opus because it never seems to fucking work on e.g. Discord and iOS. 3. MP3 was tinkered with for decades and grew into LAME with VBR so a 20 year old codec was still fantastic. 4. Opus is the greatest name for an audio codec of all time. But I suppose AI or traditional codecs will continue to improve, especially below 96k. https://github.com/AOMediaCodec/oac https://wiki.xiph.org/Opus_Recommended_Settings
