15:15 Combining DJ scratching, tangible interfaces and a physics-based model of friction sounds

Kjetil F. Hansen, TMH

This paper reports on two Short-Term Scientific Missions (STSM) in the ConGAS European Cost Action. Several sound models and (musical instrument) interfaces were combined to study how DJ gestures of scratching can be applied to new situations. In one experiment, the gestures were used to control a physics-based model of friction sounds, for instance to simulate the sound of a bowed violin string. In the other experiment, DJ gestures from the program Skipproof were adapted to the Reactable framework, allowing users to perform the complicated DJ gestures with ease. This paper describes each model and the adaption and implementation of the models.

15:30 Expressive modifications of musical audio recordings: preliminary results

Marco Fabiani, TMH

A system is described that aims to modify the performance of a musical recording (classical music) by changing the basic performance parameters tempo, sound level and tone duration. The input audio file is aligned with the corresponding score, which also contains extra information defining rule-based modifications of these parameters. The signal is decomposed using analysis-synthesis techniques to separate and modify each tone independently. The user can control the performance by changing the quantity of performance rules or by directly modifying the parameters values. A prototype Matlab implementation of the system performs expressive tempo and articulation modifications of monophonic and simple polyphonic audio recordings.
