Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same digital audio signal is converted to sound via speakers of different devices, then the audio signal can be played on various devices, but the sound is perceived differently on each device due to variations in frequency characteristics and use environments
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing optimal audio processing parameters for each device model before actual playback. The server stores processing parameters that have been predetermined based on device characteristics, so when audio is played on a specific device, the pre-prepared parameters are applied without requiring real-time analysis or user intervention.
Solution Approach 2:
The patent introduces an audio processing server as an intermediary between the audio source and the playback device. This server acts as a mediator that receives device information, selects appropriate processing parameters, and applies them to the audio signal before transmission, ensuring consistent audio quality across different devices without requiring the devices themselves to have complex processing capabilities.
2Ease of operation
If software tools for sound engineering are provided to users, then users can create customized sound, but average users lack the high level of knowledge and skill required to use these tools effectively
Solution Approach 1:
The patent implements self-service by enabling the system to automatically select and apply appropriate audio processing parameters based on device information without requiring user expertise. The server autonomously performs the sound engineering tasks by matching device characteristics with pre-stored processing parameters, eliminating the need for users to manually adjust complex audio settings.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting audio processing parameters based on device characteristics. The server stores multiple sets of processing parameters corresponding to different device types, and automatically selects the appropriate parameter set based on the detected device information, thereby optimizing audio output for each specific device without user intervention.
3Manufacturing precision
If multiple sound-setting information items are stored for different device models, then appropriate sound can be selected for each device, but the data storage and management complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the audio processing system into distinct functional components: device information acquisition, parameter selection, and audio processing. The processing parameters are segmented into discrete sets corresponding to different device models, making it easier to manage and select appropriate parameters without requiring complex real-time calculations.
Solution Approach 2:
The patent reduces data management complexity through preliminary action by pre-organizing processing parameters according to device models before runtime. The server maintains a pre-established mapping between device information and optimal processing parameters, eliminating the need for complex algorithms to determine parameter settings during actual audio playback.
Data Source
AI summary
A method for processing an audio signal, an electronic apparatus, and a computer-readable recording medium that records a program, the method, the electronic apparatus, and the program enabling appropriately-engineered sound to be listened to on various devices. After model information about a model of a device to which an audio signal is supplied has been acquired, from among a plurality of sound-setting information items associated with this model information, one of the sound-setting information items, the one corresponding to a type of sound, the type having been specified in accordance with an instruction to be input, is selected. Then, an audio signal is processed in accordance with this selected one of the sound-setting information items, and the processed audio signal is supplied to the device.
