Delay Estimation for Performing Echo Cancellation for Co-Located Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240339100 titled 'Delay Estimation for Performing Echo Cancellation for Co-Located Devices
The abstract describes a patent application where audio transmissions are received by a participant computing device in a group of co-located devices. Matched filters are generated to predict audio playback, and the best filter is identified to accurately predict the audio signal.
- Matched filters are generated based on received audio transmissions
- Filters predict audio playback caused by transmitted signals
- Coefficients in filters help capture and identify audio signals
- Best matched filter is selected to accurately predict audio playback
- Delay estimate is generated based on filter coefficients
Potential Applications: - Audio signal processing - Noise cancellation - Audio quality enhancement
Problems Solved: - Predicting audio playback accurately - Improving audio signal processing - Enhancing audio quality in co-located devices
Benefits: - Improved audio playback prediction - Enhanced audio signal processing - Better audio quality in group settings
Commercial Applications: Title: "Advanced Audio Signal Prediction Technology for Co-Located Devices" This technology can be used in: - Smart home audio systems - Conference call systems - Public address systems
Questions about the technology: 1. How does this technology improve audio quality in group settings?
- This technology enhances audio playback prediction and processing, leading to better audio quality in co-located devices.
2. What are the potential commercial uses of this audio signal prediction technology?
- This technology can be applied in smart home audio systems, conference call systems, and public address systems for improved audio quality and performance.
Original Abstract Submitted
an audio transmission is received by a participant computing device. the participant computing device is one of a plurality of participant computing devices of a participant cohort that are co-located. matched filters are generated based on the transmission that are configured to predict at least a portion of audio caused by playback of the transmitted audio signal. each of the matched filters includes coefficients. an audio signal is captured with an audio capture device. the captured audio signal corresponds to audio produced by playback of the transmitted audio signal with audio output devices of devices of the participant cohort. a matched filter is identified that most accurately predicts the audio signal. a delay estimate is generated based on a predictive contribution of one of the coefficients of the matched filter.
