Using Visualizations for Music Discovery

October 22, 2009

Hot of the presses, here are the sides for the tutorial that Justin and Paul are presenting at ISMIR 2009 on October 26.

Note that the live presentation will include many demonstrations and videos of visualizations that just are not practical to include in a PDF.  If you have the chance, be sure to check out the tutorial at ISMIR in Kobe on the 26th.

An Exploration of Real-Time Visualizations of Musical Timbre

October 16, 2009

This project explores several different ways of visualizing sets of extracted audio features in real-time. These visualizations are realized in a toolkit for the Max/MSP/Jitter programming environment. The primary purpose is to visualize timbral changes in the sense of exploratory data analysis. The program has four main parts: feature extraction, visualization, similarity, and audio control. Features are calculated by using a combination of pre-existing libraries, as e.g. the zsa.descriptors and the CNMAT analyser object. Additionally, we introduce a simple notion of timbral distance, which can be used in real-time performance situations, and present its performance for a set of different textures. The visualizations are further used to inform the control of audio effects by feature trajectories.
