Last week Chris Russell reviewed a new score scanning app, ScanScore. I kind of like that he turned this review into a comparison of the different options available, with example photos. Here is a link to the post with a quote:
ScanScore – Technology in Music Education
So, how did it work? Again, I’m not in the scanning mode right now, so I’m creating an artificial comparison (something that really isn’t crucial to me on a need-to-get-it-done-as-quickly-as-possible basis). I decided to take a a version of Beethoven’s Moonlight Sonata from IMSLP, and to see how the programs did with it.
While one example is not enough to effectively compare this kind of software, it's still interesting to see where they stack up in the example he provided. I personally find that these scanner apps require more touch up than is worth the effort. In many cases it is still easier to manually recreate the score in a notation app.
Of the apps Chris mentions in the post, Sheet Music Scanner is my favorite, even though it doesn't do triplets yet.
