Does anyone know of a local audio upscaler? Preferably Android based.

      Hello, Audio Engineer with some little knowledge regarding AI here.

      What you think of is restoring frequencies, this is possible, and commonly used in plugins for audio restaurization. I might be mistaken, but this does not improve the bitrate, but the perceived quality (which is still lossy).

      I don’t think that there is a real interest to upscale quality (not perceived quality), especially for longer (> 1 minute) material.

        It’s funny you say that. I, as most people bought a bunch of CDs back in the day and ripped a bunch before I gave up my CD drive. At the time, storage was expensive and so I did what I could at the time with MP3. As storage gets cheaper (though not cheap enough for me to go lossless), I’d like to be able to upscale my music while keeping a similar file size and have my collection mature with me until storage becomes cheap enough for me to go lossless.

        I can’t be the only person who’s thought of this.

      It wouldn’t be the original audio, the AI would just be making up new content to fill in the blanks like it does with a photo.

          If you’re OK listening to a derivative work of your input. Otherwise, it’s bad.

            Hmmm. I feel like this is one of those long-term studies that would be quite exciting? Am I wrong to be a little bit excited about programs learning how to guess correctly what should be where and subsequently how things should sound?
