CALIBRATION OF AUDIO PLAYBACK DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18424041 titled 'CALIBRATION OF AUDIO PLAYBACK DEVICES
Simplified Explanation: The patent application describes an audio playback device that adjusts audio content based on the acoustic response of a room.
Key Features and Innovation:
- The device includes a microphone, speaker, and processor.
- The processor analyzes the acoustic response of a room using the microphone input.
- A mapping is applied to the acoustic response to determine an approximated response at a different spatial location.
- The audio content output by the speaker is adjusted based on this second response.
Potential Applications: This technology could be used in smart speakers, conference call systems, and audio recording devices to optimize sound quality based on room acoustics.
Problems Solved: This technology addresses the issue of suboptimal audio quality in different room environments by dynamically adjusting audio output.
Benefits:
- Improved audio quality in various room settings.
- Enhanced user experience with clearer sound output.
- Adaptive audio playback based on room acoustics.
Commercial Applications: The technology could be valuable for companies producing audio devices for home entertainment, conferencing systems, and professional audio recording equipment.
Prior Art: Prior research in room acoustics and audio signal processing may provide insights into similar technologies or approaches.
Frequently Updated Research: Ongoing research in room acoustics, signal processing, and audio engineering may contribute to advancements in this technology.
Questions about Audio Playback Device Technology: 1. How does the device determine the acoustic response of a room? 2. What are the potential limitations of adjusting audio content based on room acoustics?
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.
