What is the best play store app for repairing corrupt audio files

[His_Queen]

I have come across audios that have content but won't play. How can I fix this via the play store please?

If the files are fixable, I would expect that you would need a computer-based program, not a phone-based app.

Which phone?
Which version of android?
Which carrier?
Which app is reporting the error?
What is the exact wording of the error?
