Abstract:
1. A method for listening to simultaneous radio transmissions, the method comprising: receiving a first radio transmission at a first carrier frequency; demodulating the first radio transmission to produce a first audio signal; adding a first differentiation cue to the first audio signal to produce a right first audio signal and a left first audio signal, said first differentiation cue comprises channel separation between the right first audio signal and the left first audio signal, said channel separation is an amplitude difference of at least about 3 dB between the right first audio signal and the left first audio signal; receiving a second radio transmission at a second carrier frequency; demodulating the second radio transmission to produce a second audio signal; adding a second differentiation cue to the second audio signal to produce a right second audio signal and a left second audio signal; providing the right first audio signal and right second audio signal to a right audio transducer; and providing the left first audio signal and the left second audio signal to a left audio transducer.
