Ask HN: AI trained to restore audio cassettes?

3 points by lighttower 6y ago ↗ HN

Has anyone trained a NN to restore audio data that has been degraded with an audio tape? Seems to work great with video [1] but never seen it done with audio. I'm trying to recover the audio of some of the kids songs I had as a kid (on cassettes) so that I can teach them to my kids... but the tapes have degraded terribly over time. Has anyone trained a massive NN to do this?

This is what I found when I searched for "neural network audio upsampling": https://kuleshov.github.io/audio-super-res/. Here is the search URL if you're interested in looking at the other links: https://duckduckgo.com/?q=neural+network+audio+upsampling&t=....

There are also companies that specialise in restoring and digitising analog media. I had some Super 8 films done by https://mediafix.de/ [German only] and the results were better than expected. They do tapes, but don’t say anything about how they can improve the sound
