Enhanced quality and variety for chorus/flange units

Chorus and flanger are two classical effects that can be found in any current digital audio FX unit. Available chorus/flanger just translate into digital implementations the behaviour and parameters typical of cost-sensitive analogue realizations. But they can be greatly improved on a digital implementation with simple additions to the software. After an introduction to chorus/flange and their digital realizations, we address two such additions (randomized modulation law, and application of energy envelope for noise control), and then discuss further improvements easily achiveable by digital means (multiscale implementations).
