AUDIO PROCESSING APPARATUS AND METHOD HAVING ECHO CANCELING MECHANISM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240056090 titled 'AUDIO PROCESSING APPARATUS AND METHOD HAVING ECHO CANCELING MECHANISM
Simplified Explanation
The abstract describes an audio processing apparatus with an echo canceling mechanism. It includes an audio transmission circuit, a DAC circuit, an ADC circuit, and a processor. The audio transmission circuit receives an input digital audio signal from an external device and generates an output analog audio signal for power amplification and playback on an external display device. The ADC circuit performs analog-to-digital conversion on an amplified signal and a received audio signal to generate an amplified digital signal and a received digital audio signal. The processor implements an echo canceling algorithm using the amplified digital signal and the received digital audio signal to generate an output digital audio signal for transmission back to the external device.
- The apparatus receives a digital audio signal from an external device.
- The DAC circuit converts the digital audio signal into an analog audio signal for power amplification and playback.
- The ADC circuit converts the amplified analog audio signal and a received audio signal into digital signals.
- The processor uses an echo canceling algorithm to cancel any echo in the digital signals.
- The output digital audio signal is transmitted back to the external device.
Potential applications of this technology:
- Audio conferencing systems: The echo canceling mechanism can improve the audio quality during conference calls by eliminating echo.
- VoIP (Voice over Internet Protocol) systems: This technology can enhance the audio experience during internet-based voice communication.
- Audio recording and playback devices: The echo canceling mechanism can improve the clarity of recorded audio and enhance the playback experience.
Problems solved by this technology:
- Echo cancellation: The apparatus effectively cancels any echo in the audio signals, resulting in clearer and more natural sound.
- Audio quality improvement: By eliminating echo, the technology enhances the overall audio quality and listening experience.
Benefits of this technology:
- Improved audio clarity: The echo canceling mechanism ensures that the audio signals are free from any unwanted echoes, resulting in clearer and more intelligible sound.
- Enhanced user experience: By providing high-quality audio with reduced echo, the technology improves the overall user experience during audio communication or playback.
- Compatibility: The apparatus can be integrated into various audio devices and systems, making it versatile and adaptable to different applications.
