Today at ISMIR Masataka Goto finally presented Songle.jp - our web service for “active music listening and content-based music browsing”. It’s awesome. I’m really proud I’m part of it: I did the chord, beat and bar annotation code. But, of course, there’s much more to it: it involved not only the other music features (segmentation melody detection), but also the whole infrastructure and web programming. The guys in Japan have really been working towards this day for two years - it’s a very ambitious product. It’s really fun also, and you can only understand if you actually check some songs out… why not start with this.
Or, if you’re more a theoretical kind of guy, these are the slides, find the paper here.
