Maraca

Maraca(num_beans=64, shake_decay=0.99, grain_decay=0.99, shake_duration=0.02, shell_frequency=12000, shell_resonance=0.9, clock=None, energy=None)

Physically-inspired model of a maraca.

Parameters: - num_beans: The number of simulated beans in the maraca (1-1024) - shake_decay: Decay constant for the energy injected per shake - grain_decay: Decay constant for the energy created per bean collision - shake_duration: Duration of each shake action, milliseconds - shell_frequency: Resonant frequency of the maraca's shell, hertz - shell_resonance: Resonanc of the maraca's shell (0-1) - clock: If specified, triggers shake actions - energy: If specified, injects energy into the maraca
