AUDIO EQUALIZATION OF AUDIO ENVIRONMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240014792 titled 'AUDIO EQUALIZATION OF AUDIO ENVIRONMENT
Simplified Explanation
The patent application describes a method of operation for equalizing the frequency response of one or more speakers. Here are the key points:
- Determine the frequency response to a measured chirp signal detected from the speakers.
- Calculate the average value of the frequency response using a high limit value and a low limit value.
- Subtract the measured response from a target response, which is based on one or more filter frequencies.
- Determine a frequency limited target filter with audible parameters based on the subtraction.
- Apply an infinite impulse response (IIR) biquad filter based on an area defined by the frequency limited target filter to equalize the frequency response of the speakers.
Potential applications of this technology:
- Audio systems: This method can be used in audio systems to ensure consistent and accurate sound reproduction across different speakers.
- Home theater systems: By equalizing the frequency response of speakers, this technology can enhance the audio experience in home theater setups.
- Automotive audio systems: The method can be applied in car audio systems to improve the quality and balance of sound output from different speakers.
Problems solved by this technology:
- Inconsistent sound quality: By equalizing the frequency response, this technology addresses issues related to variations in sound output from different speakers, ensuring a more balanced and accurate audio experience.
- Speaker distortion: The method helps to minimize distortion caused by uneven frequency response, resulting in clearer and more accurate sound reproduction.
Benefits of this technology:
- Improved audio quality: By equalizing the frequency response, this technology enhances the overall audio quality, ensuring that the sound is reproduced as intended by the audio content.
- Consistency across speakers: The method ensures that all speakers produce similar sound characteristics, creating a more immersive and balanced audio experience.
- Customizable audio settings: The audible parameters of the frequency limited target filter can be adjusted to suit individual preferences, allowing users to customize the sound output according to their preferences.
