Class ADSRParams

net.paulhertz.pixelaudio.sampler.ADSRParams

public class ADSRParams
extends Object

Value object for Minim ADSR parameters. Minim's implementation of a typical ADSR (attack, decay, sustain, release) envelope doesn't allow us to retrieve the values of its parameters after it's been created. This wrapper for ADSR makes those values available.
