Interdisciplinary Theory & Technology

This invention provides a signal processing and signal synthesis technique from a family of signal processing and signal synthesis techniques designed to readily interwork or be used individually in creating new forms of rich musical timbres. Amplitude-envelope controlled time-modulation and pitch-modulation are employed to add rich and attention-getting aspects to solo lines and chords. The amplitude envelope may be measured from the signal being modulated, a delayed version of this signal, or another signal source. Modulation characteristics and parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including those derived from the original input signal. The invention may be used individually or in conjunction with other signal processing and signal synthesis techniques in creating new forms of rich musical timbres. The invention may be also be used in spatially-distribution timbre construction.
