Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing methods are inefficient in improving voice and other audio quality due to lack of consideration for receive-side noise and distortion, leading to suboptimal noise reduction and potential distortion in audio transmission.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing audio processing methods are used, then audio processing can be performed, but audio quality improvement is inefficient due to lack of receive-side feedback
Solution Approach 1:
The patent implements a feedback mechanism where quality measurements from the receive-side are transmitted back to the transmit-side through dedicated control channels or multiplexed communication. This feedback loop enables the transmit-side to adjust noise reduction and echo cancellation algorithms based on actual receive-side conditions, transforming the one-way audio transmission into a closed-loop system that continuously optimizes audio quality.
2Ease of manufacture
If noise reduction algorithms are applied without receive-side feedback, then processing can be performed, but suboptimal noise reduction and potential distortion occur
Solution Approach 1:
The patent transforms static noise reduction algorithms into dynamic ones by continuously adjusting algorithm parameters based on real-time quality measurements from the receive-side. The system adapts noise reduction intensity, echo cancellation parameters, and other processing settings dynamically according to actual transmission conditions, ensuring optimal noise reduction accuracy without causing distortion.
3Reliability
If real-time quality measurements are implemented, then audio quality can be enhanced, but system complexity increases
Solution Approach 1:
The patent introduces dedicated control channels as intermediaries to carry quality measurement data between transmit-side and receive-side devices. These control channels serve as specialized communication pathways that efficiently transport control information without interfering with the main audio data transmission, thereby managing system complexity through structured information flow separation.
Solution Approach 2:
The patent implements multiplexed communication that allows the same communication infrastructure to handle both audio data transmission and quality measurement feedback. By combining multiple functions (audio transmission, quality measurement, and control signaling) into a unified communication system, the patent reduces overall system complexity while maintaining real-time quality enhancement capabilities.

AI summary
Methods and systems are provided for receiving by a first electronic device audio content, determining audio quality of the received audio content, which includes measuring and/or estimating quality related parameters associated with the received audio content, and communicating the quality related parameters to a second electronic device, from which the audio content was transmitted. The quality related parameters may be used to control audio related functions in the second electronic device. The audio related functions may comprise noise reduction, noise suppression, cancellation, distortion reduction, equalization, compression, enhancement and/or audio rate conversion. Determining the audio quality of the received audio content may be based on one or more noise related thresholds. The quality related parameters may be communicated to the second electronic device over a dedicated control channel setup between the devices.
