==MODIFICATION OF FAR END AUDIO SIGNALS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18520901 titled 'MODIFICATION OF FAR END AUDIO SIGNALS

==Simplified Explanation==

The abstract describes a method for modifying far-end audio signals in a conference meeting setting. The method involves analyzing the audio data, determining modifications based on predefined values and thresholds, and outputting the modified audio signals.

* The method involves establishing a conference meeting with multiple user equipment (UE) and receiving far-end audio (FEA) data from a specific UE.
* The computing device generates modified FEA by calculating time-domain and frequency-domain sums-of-absolute-differences (SAD) from the FEA data.
* If the difference between the modified FEA and a predefined value exceeds a threshold, a second modified FEA is determined and stored in a buffer before being output.

== Potential Applications ==
This technology could be applied in various communication settings where real-time audio modification is required, such as conference calls, online meetings, and teleconferencing.

== Problems Solved ==
This technology helps in improving audio quality and reducing background noise during conference meetings, ensuring clearer communication between participants.

== Benefits ==
The benefits of this technology include enhanced audio clarity, improved user experience during conference calls, and better overall communication efficiency in group settings.

== Potential Commercial Applications ==
Potential commercial applications of this technology include integration into video conferencing software, communication platforms, and telecommunication systems to enhance audio quality for users.

== Possible Prior Art ==
One possible prior art could be existing audio processing techniques used in telecommunication systems or conference call software to enhance audio quality and reduce background noise.

=== What are the specific predefined values and thresholds used in the method described in the abstract? ===

The abstract mentions determining a difference between the first modified FEA and a predefined value, as well as exceeding a predefined threshold. However, it does not specify the exact values or thresholds used in the method.

=== How does the method handle different types of audio data and adjust modifications accordingly? ===

The abstract mentions generating modified FEA by calculating time-domain and frequency-domain sums-of-absolute-differences (SAD) from the FEA data. However, it does not provide details on how the method adapts modifications based on the characteristics of the audio data.


==Original Abstract Submitted==

Techniques for modification of far end audio signals are provided. In an example method, a computing device establishes a conference meeting including a first user equipment (UE) among a plurality of UE. The computing device then receives far end audio (FEA) data from the first UE. The computing device generates first modified FEA comprising determining a time-domain sum-of-absolute-difference (SAD) from the FEA data and determines a difference between the first modified FEA and a predefined value. Responsive to the difference exceeding a predefined threshold, the computing device determines a second modified FEA comprising determining a frequency-domain SAD from the FEA data and stores the second modified FEA in a buffer. The second modified is then output from the buffer.
