ECHO FILTERING METHOD, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157158 titled 'ECHO FILTERING METHOD, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Simplified Explanation
The patent application describes an echo filtering method and apparatus for electronic devices with multiple microphones and speakers. The method involves obtaining speaker signals and microphone signals, and applying direct sound filtering to these signals to obtain a target signal.
- The method is used in electronic devices with multiple microphones and speakers.
- N speaker signals corresponding to N speakers are obtained.
- M microphone signals corresponding to M microphones are obtained.
- Direct sound filtering is performed on the speaker signals and microphone signals.
- The target signal is obtained as a result of the filtering process.
Potential Applications
- Communication devices with multiple microphones and speakers, such as smartphones or conference systems.
- Voice assistants or smart speakers that require effective echo cancellation.
- Audio recording or broadcasting equipment that needs to filter out echo for better sound quality.
Problems Solved
- Echo is a common issue in electronic devices with multiple microphones and speakers, causing audio distortion and degradation.
- Existing echo cancellation methods may not be effective in complex audio environments with multiple sound sources.
- This innovation provides a method to filter out echo and improve audio quality in such environments.
Benefits
- Improved echo filtering effect in electronic devices with multiple microphones and speakers.
- Enhanced audio quality for communication, voice recognition, and audio recording applications.
- Better user experience with reduced audio distortion and clearer sound output.
Original Abstract Submitted
An echo filtering method, an electronic device, a computer-readable storage medium, and an echo filtering apparatus are disclosed. The electronic device includes M microphones and N speakers. M and N are integers greater than 1. The method includes: obtaining N speaker signals corresponding to the N speakers (); obtaining M microphone signals corresponding to the M microphones (); and performing at least direct sound filtering on the N speaker signals and the M microphone signals to obtain a target signal (). By using this method, better echo filtering effect can be obtained.
