What is the best way to edit/split a Voice Memos recording?

Hello!
I've recorded a concert using VoiceMemo app. How can I split this concert onto separate songs? VoiceMemo's Edit function is not accessible because it requires moving a slide bar. Do you know any accessible app that can do this job? If you think it's better to be done on the computer, please recommend accessible software for Windows.
Thank you very much for any advice
