ISMIR 2008
My paper was accepted to ISMIR this year in Philadelphia. It uses the MajorMiner data we’ve collected to explore the relationship between different granularities of music metadata. That is to say, we compare the accuracy with which clip-level audio classifiers … Continue reading

Broken sound card
My desktop is getting a little old. I got it the summer before I went to college, which means its 8th birthday is coming up in August. It’s still plugging along, though, hosting this blog, among other things with a … Continue reading

Recti-Linear room simulator
For studying auditory localization and separation, it’s very important to have realistic spatial recordings. These can come from a number of sources, what I’ve been using in the past is a collection of impulse responses recorded through a KEMAR dummy … Continue reading
MajorMiner music search
We’ve started using the data that we collected through the MajorMiner game. We’re using it in two ways: making it searchable directly, and training autotaggers with it. The human search finds all of the clips that have had a particular … Continue reading

Bike trainer transcription
My parents got me a bike trainer for Hanukkah this year and I’ve been riding inside while the weather is crappy. On Graham‘s recommendation, I got the Kurt Kinetic Road Machine. It’s a fluid trainer, so the resistance comes from … Continue reading
Model-based EM Source Separation and Localization (MESSL)
Ron, Dan, and I came up with a name for the source separation and localization system we’ve been working on. It’s so much easier to refer to a five-letter handle than an abstract concept, even one that we all share. … Continue reading
Autotagging
I’ve been looking at the data we’ve collected from MajorMiner recently and I’m quite excited by the results. The idea is to use all of the clips that have been tagged “rap” to train a classifier to recognize rap. When … Continue reading
