Achieved when several musicians are playing the same musical piece at the same time but with small changes in the amplitudes and small timing differences between sounds.
A simple modification of the digital filter used in flanging leads to a structure that can be employed to simulate this sound effect. Such an effect can also be generated synthetically by a chorus generator from the music of a single musician. For example, the structure below can create a chorus of four musicians from the music of a single musician. To achieve this effect, the delays β(n) are randomly varied with very slow variations.
