Is there any GOOD local model that can be used to upscale audio?

I want to create a dataset of my voice and I have many audio messages I sent to my friends over the last year. I wanted to use a good AI model that can upscale my audio recording to make their quality better, or even upscale them to studio quality if possible. Such thing exist? All of the local audio upscaling models I have found didn’t sound better. Sometimes even worse. Thanks ❤️ submitted by /u/MaorEli [link] [comments]
