Spatial Audio-Visual Processing for Residual Audio Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video and audio capture technologies struggle with imperfect audio suppression, leading to residual audio remnants that become distracting when further audio processing is applied, especially in environments where unwanted objects are removed or replaced.
Innovation Solution
An image and sound apparatus that applies audio zoom selectively to spatial audio-visual representations, modifying audio processing based on prior audio-visual manipulations to minimize residual audio remnants by adjusting amplification levels and directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If directional audio suppression is applied to remove unwanted audio sources, then the primary audio quality is improved, but residual audio remnants remain that become distracting during further audio processing
Solution Approach 1:
The system performs preliminary audio suppression to remove unwanted audio sources before further audio processing. By applying suppression in advance and then detecting residual remnants in subsequent processing stages, the system can identify and handle these remnants before they become distracting to the user.
Solution Approach 2:
The system uses feedback by detecting residual audio remnants after suppression and using this information to adjust further audio processing. The detection of remnants provides feedback that allows the system to modify its processing approach to minimize the impact of these remnants during zooming and other audio manipulations.
2Measurement precision
If audio zoom is applied to enhance specific audio directions, then audio focus is improved, but residual audio remnants become more prominent and distracting
Solution Approach 1:
The system performs preliminary detection of residual audio remnants before applying audio zoom. By identifying the presence and characteristics of remnants in advance, the system can take preliminary actions to suppress or compensate for them before they are amplified by the zoom operation.
Solution Approach 2:
The system applies preliminary anti-action by detecting residual audio remnants and applying counter-measures before audio zoom enhances them. This may involve targeted suppression or filtering of identified remnant frequencies and directions before the zoom operation amplifies the audio signal.
3Measurement precision
If content-aware fill is used to replace unwanted visual objects, then visual quality is improved, but corresponding audio remnants remain that create audio-visual inconsistency
Solution Approach 1:
The system performs preliminary detection of audio remnants in the spatial regions where visual content has been replaced. By identifying these audio-visual inconsistencies in advance, the system can apply targeted audio processing to restore synchronization between the modified visual content and the audio signal.

AI summary
An apparatus including circuitry configured for causing audio processing to a spatial audio-visual representation of an image and sound apparatus, the spatial audio-visual representation being live or reproduced from recording; and modifying the audio processing applied to an audio-visually manipulated spatial section of the spatial audio-visual representation in response to information a prior audio-visual manipulation with data processing in the audio-visually manipulated spatial section.
