    polynomial approximation seems like a weird choice for audio, is it really more efficient than a frequency based encoding?

    also, it seems like audio compression formats have seen a lot less development in recent years than images have. I want to try encoding audio as a lossless jpeg xl now just to see how it does, I think it should be possible as jpeg xl supports extremely large image dimensions

      It’s fairly well optimized for audio. Waveforms are usually continuous and relatively repetitive. The other really important aspect is how easily it can be decoded, so that it remains a usable audio file on potentially underpowered equipment.

      Although I wonder if there exist some cases where other formats might do a better job
