I guess being too close to the DAW-space, I tend not to think about codecs. Digital audio to me is conceptually "pure" PCM (or DSD), and most things that deals with that format do not do error correction that I can think of. S/PDIF is good counter-example, and possibly (for similar reasons) ADAT might be as well.

By contrast, most audio-over-IP formats do not (they rely on the IP-level checks).

Anyway, thanks for pointing out the rather important world filled with codecs that we actually live in.



In your DAW world, AES/EBU transport parity bit corrects most single bit errors as well. It’s a testament to the comprehensive handling of the issue that you as a professional do not need to do much thinking about the problem. Point is still that audio bit errors are historically accounted for due to the obvious consequences of a discontinuity. This persists, often with layers of redundancy, despite that they rarely occur. Video bit errors, not so much
