Classification: CPC G  H | IPC G  H

Claim 13:
14. A method, comprising:
receiving a radio frequency (RF) signal at a first device, the RF signal conveying audio data and being transmitted from a second device;
measuring one or more RF signal reception or transmission characteristics of the received RF signal at the first device;
producing modified audio data at the first device by modifying information of the conveyed audio data based on the measured RF signal reception or transmission characteristics; and
reproducing analog audio acoustic sound waves from the modified audio data;
where at least one of the first device is moving relative to the second device or the second device is moving relative to the first device while the first device is receiving the RF signal being transmitted from the second device; and where the method further comprises:
making at least two measurements of the one or more RF signal reception or transmission characteristics of the received RF signal at the first device, the two measurements being made at sequential times that correspond to sequential different relative positions between the second device and the first device while at least one of the first device is moving relative to the second device or the second device is moving relative to the first device,
comparing the at least two sequential measurements of RF signal reception or transmission characteristics to determine a real time rate of change of the RF signal reception or transmission characteristics as a function of time,
producing the modified audio data at the first device by varying pitch information of the audio data based on the real time change in measured RF signal reception or transmission characteristics of the RF signal received from the second device as a function of time, and
reproducing analog audio acoustic sound waves from the modified audio data at one or more speakers of the first device to simulate a Doppler effect.
