The program has a number of interesting features:

1. The processing is done offline. That is, we run the program, and html results are generated and stored, which can be viewed and used independently of the program. This is an advantage since typically these algorithms are slow!
2. Since the results are available without the program, we can use them with opther programs to help in the transcription process, for example music notation programs.
3. Lots of improvements are on the way, I would have released more stuff, but I am off on a small vacation, and prefer to have a stable version out and get some feedback.
4. Its free!
5. Its open source!
