Algorithm AudioSR: Versatile Audio Super-resolution at Scale. Algorithm restores high frequencies. It works on all types of audio (e.g., music, speech, dog, raining, ...). It was initially trained for mono audio, so it can give not so stable result on stereo.

Metric on Super Resolution Checker for Music Leaderboard (Restored): 25.3195
