AES E-Library

Compatible FM Broadcasting of Panoramic Sound

A system for four-channel transmission over FM radio is proposed in which the most important information required to convey an acoustic picture around the horizon is allocated to the best available channels on the FM baseband. The least significant channel can be dropped to reduce noise, intermodulation, and cost with very little degradation of angular resolution.
