Abstract

An audio transmission and broadcast system to transmit and broadcast input from a plurality of sources, wherein each source is provided with a microphone or the like to collect sound emitted by a source; a plurality of spatially separated output means; the system comprising an encoder to encode sound into a digital form, the encoder allocating a vectorising element to each source; transmission means to transmit encoded data to a receiver, the receiver being operatively connected to a decoder to decode the data and transmit an audio signal through an output means; the output means allocated to a source being dependent on the vectorising element, wherein simultaneous sources are allocated spatially separated output means; and wherein the output means of a particular source remains within a predetermined spatial distance from the output means initially allocated to that source.
