Abstract
Processes and devices for equalizing an audio system that is adapted to use a loudspeaker to transduce test audio signals into test sounds. The processes and devices can involve the use of infrared signals to convey information in one or both directions between the audio system and a portable computer device that captures test sounds, calculates audio parameters that can be used in the equalization process, and transmits these audio parameters back to the audio system for its use in equalizing audio signals that are played by the audio system.
Claims20
A computer program product having a non-transitory computer-readable medium including computer program logic encoded thereon that, when performed on a device that is adapted to wirelessly communicate with an audio system, wherein the audio system is adapted to transduce test sound excitation signals into test sounds, and wherein the test sound excitation signals are generated by and wirelessly transmitted from an audio signal source to the audio system, causes the device to:
- capture the test sounds;
- and
- determine a time delay between the generation of the test sound excitation signals by, the audio signal source and the capture of the test sounds by the device, wherein the time delay includes an unknown radio delay involved in the wireless transmission of the test sound excitation signals, and wherein the time delay is determined by correlating the audio signal source with the capture of the test sounds by the device.
A device that is adapted to wirelessly communicate with an audio system, wherein the audio system is adapted to transduce test sound excitation signals into test sounds, and wherein the test sound excitation signals are generated by and wirelessly transmitted from an audio signal source to the audio system, the device comprising:
- a microphone that is configured to capture the test sounds;
- and
- a processor that is configured to determine a time delay between the generation of the test sound excitation signals by the audio signal source and the capture of the test sounds by the device, wherein the time delay includes an unknown radio delay involved in the wireless transmission of the test sound excitation signals, and wherein the time delay is determined by correlating the audio signal source with the capture of the test sounds by the device.
A system, comprising:
- an audio system that is adapted to transduce test sound excitation signals into test sounds, wherein the test sound excitation signals are generated by and wirelessly transmitted from an audio signal source to the audio system;
- and
- a device that is adapted to wirelessly communicate with an audio system, wherein the device comprises a microphone that is configured to capture the test sounds and a processor that is configured to determine a time delay between the generation of the test sound excitation signals by the audio signal source and the capture of the test sounds by the device, wherein the time delay includes an unknown radio delay involved in the wireless transmission of the test sound excitation signals, and wherein the time delay is determined by correlating the audio signal source with the capture of the test sounds by the device.
