Adaptive digital audio effects require several implementations, according to the context. This paper brings out a general adaptive DAFx diagram, using one or two input sounds and gesture control of the mapping. Effects are classified according to the perceptive parameters that the effects modify. New adaptive effects are presented, such as martianization and vowel colorization. Some items are highlighted, such as specific problems of real-time and non real-time implementation, improvements with control curve scaling, and solutions to particular problems, like quantization methods for delay-line based effects. To illustrate, musical applications are pointed out.
