Phase-staggered multi-channel signal panning
First Claim
1. A system for controlled staggered panning of multi-channel audio signals, said system comprising:
- a master time-varying control signal;
a processor for generating at least three panning control signals responsive to a distinct phase-staggered function of said master time-varying control signal; and
at least three controllable audio signal panning elements individually structured for panning a separate incoming audio signal responsive to an associated one of said at least three panning control signals.

Abstract
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. Phase staggered multi-channel signal panning creates spatial perturbation and chase effects for subtle or dramatic application, and may be swept with control signals from a low-frequency oscillator, transient envelope, or other source. Phase-staggering and modulation 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 also be used in spatially-distributed timbre construction.

17. A method for controlled staggered panning of multi-channel audio signals, said method comprising:
-
receiving at least three incoming audio signals at an associated at least three controllable signal panning elements, wherein each panning element of said at least three controllable signal panning elements receives one of said at least three incoming audio signals; producing a plurality of outgoing panned audio signals at each panning element of said at least three controllable signal panning elements in response to a separate panning control signal associated with each of said at least three controllable signal panning elements; and generating said panning control signal for each panning element of said at least three controllable signal panning elements, wherein each panning control signal of said at least three panning control signals is generated using an associated function of a common time-varying control signal, wherein the common time-varying control signal varies periodically. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
