Artificial Intelligence to improve decoding of MP3 files

"Using a GAN architecture to restore heavily compressed music files"

The article claims that AI (artificial intelligence) can "guess" the best way to restore some of the stuff lost when music is compressed to MP3.

Few years ago i was saying that maybe we can use AI to recreate lost info from compressed files:)
When you look what they're doing with images and Dall-E, i wouldn't be surprised if somebody finds a way how to train a model with compressed music. Maybe thats a chance for Spotify to finally gets "lossless" streaming?

I am not too interested in AI as a means of improving MP3 playback (it's always better to go back to the original CD rip - if available).
But it could be really good for improving old recordings (e.g. 78's) by removing surface noise, extending the frequency range etc. It could even (dare I say it) produce a convincing stereo effect from a mono record.

I'm with you on this James. I would suspect that figuring out how to improve a lossy jpeg file for a photo file is not that much different than an mp3 for music.... to a computer/engineer.

But its probably only relevant in very niche situations.
