tambourine is a semi-physical model of a tambourine sound. It is one of the PhISEM percussion opcodes. PhISEM (Physically Informed Stochastic Event Modeling) is an algorithmic approach for simulating collisions of multiple independent sound producing objects.
idettack -- period of time over which all sound is stopped
inum (optional) -- The number of beads, teeth, bells, timbrels, etc. If zero, the default value is 32.
idamp (optional) -- the damping factor, as part of this equation:
damping_amount = 0.9985 + (idamp * 0.002)
The default damping_amount is 0.9985 which means that the default value of idamp is 0. The maximum damping_amount is 1.0 (no damping). This means the maximum value for idamp is 0.75.
The recommended range for idamp is usually below 75% of the maximum value.
imaxshake (optional, default=0) -- amount of energy to add back into the system. The value should be in range 0 to 1.
ifreq (optional) -- the main resonant frequency. The default value is 2300.
ifreq1 (optional) -- the first resonant frequency. The default value is 5600.
ifreq2 (optional) -- the second resonant frequency. The default value is 8100.
kamp -- Amplitude of output. Note: As these instruments are stochastic, this is only an approximation.
Here is an example of the tambourine opcode. It uses the files tambourine.orc and tambourine.sco.
