Cantillion

Cantillion is a web based Flash application that allows ethnomusiologists around the world to explore tropes and gestures from partially annotated chant traditions from around the world. We are working on using Marsyas to generate the pitch contours and to perform Dynamic Time Warping similiarity calculations between different tropes.

MarGrid online

MarGrid online is a Flash based web application that allows users to interactively browse a two-dimensional representation of different collections of music. The 2D representations are generated using a Self-Organizing Map (SOM) which maps a high dimensional feature space to two dimensions. Both the feature extraction and SOM algorithm are calculated using Marsyas.

MarGrid Tags

MarGrid Tags is a Flash based web application that allows users to interactively browse a two-dimensional representation of different collections of music. The 2D representations are generated using a Self-Organizing Map (SOM) which maps a high dimensional feature space to two dimensions. Both the feature extraction and SOM algorithm are calculated using Marsyas.

CAL500

The CAL500 dataset is a collection of songs curated by Doug Turnbull which has 500 songs of a variety of genres, each of which has been tagged with a variety of semantic tags by human listeners. We recently used Marsyas to predict tags for each of the songs in this collection using a new technique called stacked generalization. Check it out at cal500.sness.net.

Panning Pedagogy

A Flash application that, using Marsyas, takes audio data, calculates the spectrum for the left and right channels, and calculates the Stereo Panning Spectrum from this data. It is then graphically displayed in a web application. Look for similar programs inside of Marsyas that display this data using 3D OpenGL.

Neil's Skookum MarSystem Network Constructor

A Java web applet built with Processing that allows users to construct Marsyas networks inside a web browser.
