this is not about Amadeus - but a general question about audio editing.
I just received some analog recordings from a radio broadcast where i played some tunes with my former ensemble about 25 years ago.
I didn't know that this recordings exist.
Someone unknown recorded the broadcast on MC.
The tunes are played nice

Totally distorted.
I'm not an expert in audio editing and i know: what is gone/broken is gone/broken.
But perhaps someone has a hint how to improve the quality of my old recordings a little bit?
Thanks for any hint and best regards, Karl
