Is there a tool to search for audio files that are corrupt? Every once and a while I go into packs that didn't download properly and find sounds that won't play. They are their full file size but they have no use because they are corrupt. Is there a tool I could use to batch-locate them and delete them?

 

No idea if you need a GUI.
If you're handy with the command line, grab a copy of fd and ffmpeg:

ffmpeg -loglevel error -hide_banner -nostats -i the_file_to_check.wav -f null -

It'll stay silent if the file works and spit out an error if the file is corrupt.

For all wav, flac and aif files in a folder and all its subfolders:

fd -ewav -eflac -eaif -tf -x ffmpeg -loglevel error -hide_banner -nostats -i "{}" -f null -

Same deal. Silence if the files decode correctly, error msg if not.
