I have began my summer job at the CompMusic Project at the Music Technology Group, Barcelona, Spain (computer music, audio signal processing, music information retrieval). I was not familiar with this area of signal processing applied in music, but apparently the interest in music info retrieval and info processing has been great worldwide. Some resources:
1.MusicBrainz-the Open Music Encyclopedia. Currently lots of metadata CD information of CompMusic project are stored at MusicBrainz.
2.ISMIR 2013 (The annual Conference of the International Society for Music Information Retrieval (ISMIR) is the world’s leading research forum on processing, searching, organizing and accessing music-related data, 2013 conference in Brazil, Nov.2013).
3.Mandeley--a online reference pdf organization tool.
4.MEI--The Music Encoding Initiative (MEI) is a community-driven effort to create a commonly-accepted, digital, symbolic representation of music notation documents. We strive to establish the design principles and the technological and representational requirements that will enable the discipline of musicology to take full advantage of digital technologies. We are working to provide guidelines and tools that can be widely used by libraries, museums, and individual scholars to encode musical scores for research, teaching, and preservation activities.
