I’ve been wanting something like this. I have a lot of old mixes from the radio on tape, that I’ve converted and tried to enhance but could never get it just right (I’m no audio engineer). This app really brings that old audio to life. It sounded just like I was listening to it live on the radio again, it’s that good. One problem I have with it is it only displays the song title on my car system.
