Abstract: A musical keyboard touch sensor pad having a plurality of integrated sensors disposed in an array is disclosed. The plurality of integrated sensors represents a keyboard key. A processor is electronically coupled to the plurality of integrated sensors. The processor is programmed to receive signals from several of the plurality of integrated sensors and to generate a sound signal based on input from the several of the plurality of integrated sensors. The output is variable based on the number in the plurality and the location of the plurality in the array. An audio output device is electronically coupled to the processor to generate a sound based on the sound signal. A keyboard using a plurality of the sensor pads as well as a method of generating sounds from the keyboard are also disclosed.

Abstract: An analysis and synthesis system for sound is provided that can independently modify characteristics of audio signals such as pitch, duration, and timbre. High-quality pitch-scaling and time-scaling are achieved by using a technique for sinusoidal phase compensation adapted to a sinusoidal representation. Such signal modification systems can avoid the usual problems associated with interpolation-based re-sampling so that the pitch-scaling factor and the time-scaling factor can be varied independently, arbitrarily, and continuously. In the context of voice modification, the sinusoidal representation provides a means with which to separate the acoustic contributions of the vocal excitation and the vocal tract, which can enable independent timbre modification of the voice by altering only the vocal tract contributions. The system can be applied to efficiently encode the pitch in sinusoidal models by compensating for pitch quantization errors. The system can also be applied to non-speech signals such as music.
