About

Marsyas (Music Analysis, Retrieval and Synthesis for Audio Signals) is an open source software framework for audio processing with specific emphasis on Music Information Retrieval applications. It has been designed and written by George Tzanetakis (gtzan@cs.uvic.ca) with help from students and researchers from around the world. Marsyas has been used for a variety of projects in both academia and industry.

Featured Project

ASTA - Automatic Subtitle Timing Annotator

Subtitling a video/song is a tedious task, not only one has to write the subtitle, but also one has to specify its timing (start and end times). ASTA project tries to automatically determine the subtitles timing based on the, possibly polyphonic, audio input. We found Marsyas to be the most suitable tool for both signal processing (i.e. feature extraction) and machine learning (i.e. training and classification). Beside its efficiency, it provides such a complete solution to audio-analysis that we didn't need any other library. We thank Marsyas team for open-sourcing such a great project.

Featured Web Demo

Cantillion 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.
