CALIBRATION OF AUDIO PLAYBACK DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240251213 titled 'CALIBRATION OF AUDIO PLAYBACK DEVICES
The abstract describes an audio playback device that uses a microphone, speaker, and processor to adjust audio output based on the acoustic response of a room.
- The processor outputs audio content through the speaker and receives an indication of the audio content through the microphone.
- It determines the first acoustic response of the room based on the received indication.
- A mapping is applied to the first acoustic response to determine a second acoustic response, indicative of the room's acoustic response at a different spatial location.
- The second audio content output by the speaker is adjusted based on the second response.
Potential Applications: - Home audio systems - Conference room audio setups - Live event sound systems
Problems Solved: - Improving audio quality in different room environments - Enhancing the listening experience for users
Benefits: - Customized audio output based on room acoustics - Better sound quality in various settings
Commercial Applications: Title: "Smart Audio Playback Device for Enhanced Sound Quality" This technology can be used in smart speakers, home theater systems, and professional audio equipment to optimize sound output based on room acoustics, providing a superior listening experience for users.
Questions about the technology: 1. How does the device determine the acoustic response of the room? - The device uses the microphone to capture the audio content and analyze the room's acoustic properties to adjust the audio output accordingly. 2. What are the potential limitations of this technology in real-world applications? - The technology may face challenges in accurately mapping the acoustic response of complex room environments with multiple sound reflections.
Original Abstract Submitted
an audio playback device comprises a microphone, a speaker, and a processor. the processor is arranged to output by the speaker first audio content and receive by the microphone an indication of the first audio content. a first acoustic response of a room in which the audio playback device is located is determined based on the received indication of first audio content. a mapping is applied to the first acoustic response to determine a second acoustic response. the second acoustic response is indicative of an approximated acoustic response of the room at a spatial location different from a spatial location of the microphone. the second audio content output by the speaker is adjusted based on the second response.
