You’d need to be more specific. If you’re talking about taking CD quality audio and Up-sampling to “high res” audio, what you’re actually doing is fabricating new inaudible frequencies which do nothing except potentially degrade the audible sound if your tweeters aren’t up to the task of reproducing these useless frequencies perfectly. What I am excited for is a narrowband to wideband algorithm which can turn a Ye Olde Microphone recording or possibly even a telephone conversation into something resembling a modern recording. Obviously there’s only so much you can do with a recording made on a terrible microphone, but it should be possible to make historical recordings clearer.
