Augmented Notes integrates scores and audio files to produce interactive multimedia websites in which measures of the score are highlighted in time with music.

To get started making your own website, upload mp3 and ogg versions of your audio file, images of the pages of your score, and, if you have one, an MEI file containing measure boundaries, then hit submit below. Augmented Notes will help you mark the measures on the score and assign them times, and will output a zip file of everything you need to have your own website.
