While automatic music transcription is a challenging problem, several programs exist that attempt to transcribe music, especially for simple songs like single instrument recordings. So, how do these programs compare in terms of accuracy? Below I show side-by-side results for 5 different transcription programs, including AnthemScore. I selected 11 short song segments that range from very simple to very challenging.
