Simulated playing excerpt with full clarinet model (approx far field pressure)

This excerpt is the simulated mouthpiece pressure from a full clarinet model described in the POMA ISMRA conference paper. Changes between notes are accomplished by a set of hard switches opening or closing the acoustic flow at the relevant tone holes. For switches of one or two holes, the note transitions are reasonably smooth. This excerpt also includes the note change from A4 to B4, which requires the register key to be opened and most other holes to be closed. It also requires a moderate change in blowing pressure to maintain approximately constant playing amplitude. That change works, but is a less stable transient.

The approximation for the far field radiated pressure is calculated by adding the calculated far field pressures from all of the open tone holes to that from the bell. Each tone hole is terminated with a radiation impedance that is an approximation to the impedance of a piston of the same diameter in an infinite baffle.

The tone hole radiated pressure waveforms have some very large transients of a one or two time points duration when a tone hole is opened or closed. These transients have been significantly clipped, but not totally removed. For all of these reasons, the author believes that the radiated pressure waveforms are not accurate approximations. However they are provided for review.
