Audio Object Information Image Visual Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to adjust the volume and other audio characteristics of audio objects in video content encoded with object audio encoding technology, as selecting the desired audio object solely by listening to the output sound is extremely challenging.
Innovation Solution
An audio processing apparatus and method that displays audio object information images based on positional information, allowing users to select and adjust audio objects visually, with features like volume and sound quality adjustment, and rendering processing to position audio objects accurately on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If object audio encoding technology is used to encode multiple audio objects with positional information, then the ability to manipulate individual sound sources is improved, but the difficulty of selecting and adjusting specific audio objects during reproduction worsens
Solution Approach 1:
The patent introduces a visual dimension by displaying audio object information images on the display unit. Instead of relying solely on auditory selection, the system projects audio objects into a visual space where users can see and select them. This dimensional transition from audio-only to audio-visual interface resolves the contradiction by making individual audio objects distinguishable and selectable through visual cues.
Solution Approach 2:
The patent introduces an intermediary visual interface (audio object information images) between the encoded audio objects and the user. This intermediary layer translates invisible audio object data into visible representations that users can interact with, facilitating easy selection and manipulation of specific audio objects without directly exposing the complex encoding structure.
2Measurement precision
If audio object information is encoded with positional metadata, then the precision of audio object positioning is improved, but the complexity of the encoding system worsens
Solution Approach 1:
The patent extracts positional information from the encoded audio objects and displays it separately as visual information on the display unit. By separating the positional metadata from the audio signal processing path and presenting it visually, the system maintains high positioning precision while reducing the operational complexity of managing encoded audio objects.

AI summary
The present technology relates to an audio processing apparatus and method and a program that are configured to adjust audio characteristics more easily. This audio processing apparatus has a display control unit configured, on the basis of object positional information of an audio object, to cause a display unit to display an audio object information image indicative of a position of the audio object and a selection unit configured to select the predetermined audio object from among one or a plurality of the audio objects. The present technology is applicable to video/audio processing apparatuses.
