For several years, we have been developing and studying computer-simulated models
of brass instruments including the player's lips. We demonstrate here such
a physical model. It is played in real-time with MIDI events. We present recent
developments concerning both physical functioning and real-time controls. They
result in great improvements of sound quality and musical expressivity. To better
understand the physics of real lips, we have build a latex model of the lips.
We show that this artificial mouth can play a trumpet like a real trumpet player.
We analyse lips behavior and acoustic measurements. We make comparisons between
naturally blown trumpet signals, artificially blown trumpet signals, and simulations
with our computer model.
