Zeta violin latencies and techniques

Zeta violin converts analog sound to MIDI via multi-channel IVL PitchRider hardware.The problem is the delay in calculating the pitch. The purpose of this study is to measure the latency which depends on many factors such as pitch, articulation, dynamics, etc. Also new violin techniques will be investigated to minimize the latency.

Timbral recognition using lazy learning

How do we recognize timbre? How well can we recognize using just the steady-state portion of musical timbre? Can machines do this in realtime?

Developing Virstual Concert Hall

Music students preparing for recitals seldom are able to rehearse in the concert hall in which the recital is to be performed because of scheduling conflicts. Rehearsal in the same acoustic space that the performer will play in, however, is important to a successful performance. We would like to develop a system with which a performer can rehearse in a practice room, and his instrument?s acoustic signal would be processed by NT workstations in such a way that the acoustics of a specific concert hall will be replicated. This is accomplished by the performer playing into a microphone, applying digital signal processing to the signal, and playing back signals into the practice room (through small multimedia speakers) which replicate the acoustics of a desired hall. Initial experiments with "off-the-shelf" processing equipment have been promising. We would, however, need to create models for specific concert halls and develop our own signal processing algorithms.
