Terminal Audio Sensor Volume Adjustment for Stereo Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to maintain a stereophonic effect in video recordings when the terminal's location changes, leading to poor recording quality due to inconsistent audio channel volumes.
Innovation Solution
A method and apparatus that utilize two sound channels and at least two audio sensor units, along with a photographing unit, to determine the terminal's placement status and adjust the audio sensor units' volumes accordingly, ensuring a preset threshold difference between sound channels is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal placement location is not fixed, then the terminal can be used more flexibly, but the stereophonic effect of the recorded video deteriorates
Solution Approach 1:
The system dynamically adjusts the recording correspondence between audio sensor units and sound channels based on the terminal's placement status. Different placement orientations (e.g., horizontal, vertical, upside-down) trigger different audio channel mappings to maintain stereophonic effect quality regardless of terminal orientation.
Solution Approach 2:
The system changes the volume parameters of audio sensor units based on placement status. By adjusting volume levels dynamically according to terminal orientation, the system ensures that the difference between volume passing through left and right sound channels remains within a preset threshold, maintaining consistent stereophonic quality.
2Adaptability or versatility
If the terminal placement status changes, then the recording scenario becomes more varied, but the audio channel volume consistency deteriorates
Solution Approach 1:
The system uses acceleration sensors to detect terminal placement status and provides feedback to the audio processing system. Based on this feedback, the system automatically adjusts the recording correspondence and volume levels of audio sensor units to maintain volume consistency within the preset threshold across different recording scenarios.
Solution Approach 2:
The recording correspondence between audio sensor units and sound channels is dynamically adjusted based on detected placement status. The system transitions between different audio channel mappings depending on whether the terminal is held horizontally, vertically, or in other orientations, ensuring consistent audio quality throughout.

AI summary
Embodiments of the present invention provide a recording method, apparatus, and terminal, and relate to the audio and video recording and playing field. The present invention is invented to prevent a problem that a stereophonic effect of a recorded video is poor as a result of a change in location status of a terminal. The method includes: acquiring a placement status parameter of a terminal according to current placement status of the terminal; determining that one photographing unit of at least one photographing unit is in a started state; determining a recording correspondence between at least two audio sensor units and two sound channels according to the acquired placement status parameter and the determined photographing unit in the started state; and adjusting volume of the at least two audio sensor units according to the recording correspondence between the at least two audio sensor units and the two sound channels, so that a difference between volume that passes through the two sound channels is less than a preset threshold. The present invention may be applied to audio processing technologies.
