Abstract
An improved control structure for music synthesis is provided in which: 1) the sound representation provided to the adaptive function mapper allows for a greatly increased degree of control over the sound produced; and 2) training of the adaptive function mapper is performed using an error measure, or error norm, that greatly facilitates learning while ensuring perceptual identity of the produced sound with the training example. In accordance with one embodiment of the invention, sound data is produced by applying to an adaptive function mapper control parameters including: at least one parameter selected from the set of time and timbre space coordinates; and at least one parameter selected from the set of pitch, .DELTA.pitch, articulation and dynamic. Using an adaptive function mapper, mapping is performed from the control parameters to synthesis parameters to be applied to a sound synthesizer. In accordance with another embodiment of the invention, an adaptive function mapper is trained to produce, in accordance with information stored in a mapping store, synthesis parameters to be applied to a sound synthesizer, by steps including: analyzing sounds to produce sound parameters de…
