Minimizing Echo Caused by Stereo Audio Via Position-Sensitive Acoustic Echo Cancellation - A simplified explanation of the abstract
This abstract first appeared for US patent application 18297299 titled 'Minimizing Echo Caused by Stereo Audio Via Position-Sensitive Acoustic Echo Cancellation
The patent application describes a system for obtaining a stereo audio output signal based on the position of a participant in a teleconference relative to multiple audio output devices within the teleconferencing space. This signal is then played back on the audio output devices within the space.
- The system receives an audio input signal captured by an audio capture device within the teleconferencing space, which may include audio from the playback of the stereo audio output signal by the audio output devices.
- Position information is used to perform an Acoustic Echo Cancellation (AEC) process on at least a portion of the audio input signal, reducing echo and improving audio quality.
Potential Applications: - Teleconferencing systems - Virtual meetings - Audio conferencing solutions
Problems Solved: - Echo and audio feedback in teleconferencing environments - Position-based audio optimization
Benefits: - Improved audio quality in teleconferencing - Enhanced user experience - Clearer communication in virtual meetings
Commercial Applications: The technology can be utilized in telecommunication companies, video conferencing software providers, and businesses looking to enhance their virtual meeting capabilities.
Questions about the technology: 1. How does the system determine the position of the participant within the teleconferencing space? 2. What are the key advantages of using Acoustic Echo Cancellation in teleconferencing environments?
Original Abstract Submitted
A stereo audio output signal is obtained based on position information indicative of a position of a participant of a teleconference relative to a plurality of audio output devices, wherein both the participant and the plurality of audio devices are located within a teleconferencing space. Playback of the stereo audio output signal is caused at the plurality of audio output devices located within the teleconferencing space. An audio input signal captured at an audio capture device located within the teleconferencing space is received, wherein at least a portion of the audio input signal comprises audio caused by playback of the stereo audio output signal by the plurality of audio output devices. The position information is used to perform an Acoustic Echo Cancellation (AEC) process to the at least the portion of the audio input signal.
