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 that generates 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. The system then plays back the stereo audio output signal through the audio output devices. Additionally, 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. The position information is used to perform an acoustic echo cancellation process on the audio input signal.
- Stereo audio output signal is generated based on participant position in a teleconference.
- Playback of the stereo audio output signal is done through multiple audio output devices in the teleconferencing space.
- Audio input signal captured by an audio capture device is received, potentially containing audio from the playback.
- Position information is utilized for acoustic echo cancellation on the audio input signal.
Potential Applications: - Teleconferencing systems - Virtual meetings - Audio spatialization technologies
Problems Solved: - Elimination of echo in audio input signals during teleconferencing - Improved audio quality for participants in a teleconference
Benefits: - Enhanced audio experience for teleconference participants - Clearer audio transmission - Immersive sound environment
Commercial Applications: Title: "Advanced Teleconferencing Audio Systems for Enhanced Communication" This technology can be used in telecommunication companies, conference room equipment manufacturers, and virtual meeting platforms to improve audio quality and user experience during teleconferences.
Questions about the technology: 1. How does the system determine the position of the participant in the teleconference space?
The system likely uses sensors or tracking technology to determine the participant's position relative to the audio output devices.
2. What are the potential challenges in implementing acoustic echo cancellation in a teleconferencing environment?
Challenges may include real-time processing requirements and the need for accurate position tracking to effectively cancel echo.
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.
