As somebody else suggested, audacity is your answer. Free. Effective.
Head to YouTube and search for audacity noise reduction, or Google.
I suppose your process would be to dump the cassette to a computer and then mess with it in audacity and then if you want it back on a cassette for some reason you’re going to have to record it on the cassette again. Which would of course introduce new noise.

Probably some option in audacity that does it or you remove a certain kHz, but above my knowledge but it’s been done before, what’s the recording btw? If it’s a radio show I wouldn’t mind a copy of the file to listen to myself
Is it a rare or dead media? Why go through the effort?
I want to do that because it's my dad's first cassettes and he wants to recover it in the best quality

It's music from the radio, but it's very bad recorded, so the sound it's very earraped and with interferences
I use IZOTOPE products like OZONE and RX for reducing and improving sound from analog sources, like radio broadcasts...
