Assignee: SILICON LABORATORIES INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 23:
24. An apparatus, comprising at least one programmable integrated circuit coupled to radio circuitry of a first device, the programmable integrated circuit being programmed to operate the first device to:
receive a radio frequency (RF) signal at a first device, the RF signal conveying audio data and being transmitted from a second device;
measure one or more RF signal reception or transmission characteristics of the received signal 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 apparatus further comprises at least a first speaker and a second speaker; where the audio data comprises at least first channel audio data and second channel audio data; and where the programmable integrated circuit is further programmed to operate the first device to:
produce the modified audio data at the first device by individually varying volume level and/or pitch level information of the first channel audio data relative to volume level and/or pitch level information of the second channel audio data based on the measured RF signal reception or transmission characteristics of the RF signal received from the second device, and
simultaneously reproduce analog audio acoustic sound waves from the first channel information of the modified audio data at the first speaker of the first device and reproduce analog audio acoustic sound waves from the second channel information of the modified audio data at the second speaker of the first device; and

where the first device comprises a portable wireless audio data receiver system that comprises a first speaker configured to be worn adjacent a left ear of a human user and a second speaker configured to be worn adjacent a right ear of the same human user; and where the programmable integrated circuit is further programmed to operate the first device to:
determine at least one of position, orientation and/or direction of the first device relative to the second device based on the measured one or more RF signal reception or transmission characteristics of the received RF signal at the first device,
produce the modified audio data at the first device by individually varying volume level and/or pitch level information of the first channel audio data relative to volume level and/or pitch level information of the second channel audio data based on the determined position, orientation and/or direction of the first device relative to the second device to produce modified audio data having first and second audio channels that have different volume level and/or pitch level information relative to each other such that the volume level information and/or pitch level information of the first channel audio data is different from the volume level information and/or pitch level information of the second channel audio data to indicate to a user of the first device the direction from which the RF signal is received, and

simultaneously reproduce analog audio acoustic sound waves from the first channel information of the modified audio data at the first speaker of the portable wireless audio data receiver system and reproducing analog audio acoustic sound waves from the second channel information of the modified audio data at the second speaker of the portable wireless audio data receiver system.
