Has Improved but Still Needs More Work

I have been using this app on and off. On older recordings on Apple, there seems to be audio issues the playback through this app. It simply sounded horrible. I shut the app off and relistened to the song and it was ok.
I reopened the app and retried the song and again it sounded terrible.
When I used the app for newer recordings, most sounded better.
