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 20240340608 titled 'Minimizing Echo Caused by Stereo Audio Via Position-Sensitive Acoustic Echo Cancellation
The patent application describes a system where stereo audio output is generated based on the position of a participant in a teleconference relative to multiple audio output devices within the teleconferencing space. The audio output signal is played back through these devices, and an acoustic echo cancellation process is used to eliminate feedback caused by the playback.
- Stereo audio output signal is created based on participant position in a teleconference space.
- Multiple audio output devices within the space play back the stereo audio signal.
- Acoustic echo cancellation process is applied to eliminate feedback from playback.
- Audio input signal captured within the teleconferencing space is used for the process.
- Position information is crucial for the accurate implementation of the acoustic echo cancellation process.
Potential Applications: - Teleconferencing systems - Virtual meetings - Audio conferencing solutions
Problems Solved: - Elimination of audio feedback in teleconferencing environments - Improved audio quality for participants in virtual meetings
Benefits: - Enhanced audio experience for teleconference participants - Clearer communication during virtual meetings - Reduction of audio disturbances in teleconferencing spaces
Commercial Applications: Title: Advanced Teleconferencing Audio Systems This technology can be utilized in various industries for virtual meetings, teleconferencing, and audio conferencing solutions. Companies offering telecommunication services, video conferencing platforms, and virtual event organizers can benefit from the improved audio quality and reduced feedback in their services.
Questions about the technology: 1. How does the system determine the position of the participant within the teleconferencing space? - The system likely uses sensors or tracking technology to determine the participant's position. 2. What are the potential challenges in implementing the acoustic echo cancellation process effectively in a teleconferencing environment? - Challenges may include background noise interference, varying room acoustics, and real-time processing requirements.
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.
