Classification: CPC G  H | IPC G  H

Claim 34:
35. A system, comprising:
a first device having at least one first programmable integrated circuit coupled to radio circuitry of the first device;
a second device having at least one second programmable integrated circuit coupled to radio circuitry of the second device;
where the second programmable integrated circuit of the second device is programmed to control operation of the second device to transmit a radio frequency (RF) signal from the second device to the first device; and
where the first programmable integrated circuit of the first device is programmed to operate the first device to:
receive the RF signal at the first device, the RF signal conveying audio data and being transmitted from the second device,
measure one or more RF signal reception or transmission characteristics of the RF signal as it is received at the first device,
produce 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
reproduce analog audio acoustic sound waves from the modified audio data;

where the first device comprises one or more speakers; where at least the first device is movable relative to the second device or the second device is movable relative to the first device while the second device; and where the first programmable integrated circuit is further programmed to operate the first device to:
make 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;
compare 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;
produce 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
reproduce analog audio acoustic sound waves from the modified audio data at the one or more speakers of the first device to simulate a Doppler effect.
