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 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.
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.
