Abstract

A multi-dimensional audio processor receives as an input either a single channel signal or a two channel signal from an audio signal source; for example a musical instrument or an audio mixer. The processor is programmable to divide the input among at least 3 output channels in a user-defined manner. The processor is also user programmable to provide a variety of effect and mixing functions for the output channel signals.

Claims

1. A method of processing at least one channel input signal comprising the steps of:

receiving the input signal;

modifying the input signal to produce a second signal;

variably controlling the input and second signals; and

mixing the variably controlled signals to produce variably controllable third, fourth and fifth channel output signals.

2. A circuit for processing at least one channel input signal comprising:

means for receiving the input signal;

means for modifying said received signal to produce a second signal;

means for variably controlling said input and second signals; and

means for mixing said variably controlled signals to produce variably controllable third, fourth and fifth channel output signals.
