Virtual Acoustic Synthesis

The Instrument

The key block in this algorithm is the instrument, since it is here that the fundamental tone

or “timbre” of the sound is defined. The instrument model consists primarily of a driver —

the reed/mouthpiece, lip/mouthpiece, or bow/string system — and a resonant system corre-

sponding to the tube and air column or string.

One of the remarkable features of the Virtual Acoustic Synthesis system is that just about

any driver can be used with any type of pipe or string.

• The sound thus produced is amplified and sustained by the body of the instrument.

• The pitch of the sound is determined by the length of the air column or string, and the timbre is a complex

product of the driving source (reed, lip, air, string), the shape of the resonant cavity, the materials from

which the instrument is made, etc.

Drivers

Pipes/String

In all these instruments pressure applied here (the

driving point) causes vibration which results in sound.

Reed vibration

Lip vibration

Air vibration

String vibration
