Audio Profile Configuration for USB External Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External audio devices connected to computing devices via USB often bypass the internal audio codec, leading to a loss of optimized audio profiles, resulting in suboptimal audio quality for specific types of audio content.
Innovation Solution
The computing device employs a detection engine to identify supported codecs in external audio devices and provides tailored audio profiles or defaults to ensure optimal audio playback, using a combination of hardware and software to manage audio settings and parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external audio devices with internal codecs are connected via USB, then audio playback functionality is enabled, but the internal audio codec is bypassed causing loss of optimized audio profiles
Solution Approach 1:
The patent introduces an intermediary software layer (audio driver or system software) that sits between the audio application and the USB audio device. This intermediary intercepts audio data before it reaches the external device, applies the optimized audio profile processing, and then transmits the processed audio via USB. This resolves the contradiction by maintaining profile optimization (improving_feature) while still allowing USB connection with internal codec (worsening_feature context).
Solution Approach 2:
Instead of allowing the external audio device to process audio independently through its internal codec, the system inverts the processing flow by having the computing device apply audio profiles to the audio data stream before transmission. This inversion ensures that optimized profiles are applied even when external devices with internal codecs are connected, resolving the quality consistency issue.
2Adaptability or versatility
If default audio profile is used for external audio devices, then compatibility is improved, but audio quality for specific audio types deteriorates
Solution Approach 1:
The system dynamically selects and applies appropriate audio profiles based on the type of audio content being played and the characteristics of the connected external device. Rather than using a static default profile, the system adapts the audio processing in real-time, switching between different profiles (e.g., music, speech, gaming) to optimize quality while maintaining broad device compatibility.
Solution Approach 2:
The patent changes audio parameters (such as sample rate, bit depth, equalization settings, and processing algorithms) based on the detected audio type and device characteristics. This allows the system to maintain compatibility across different devices while optimizing audio quality for specific audio types by adjusting parameters rather than relying on a fixed default profile.
3Ease of operation
If USB connection is used for external audio devices, then connection flexibility is improved, but audio codec bypass and profile loss occur
Solution Approach 1:
The system performs preliminary action by capturing and processing audio data at the source (computing device) before transmission to the external USB audio device. Audio profiles are applied to the audio stream in advance, ensuring that profile information is preserved and embedded in the transmitted data, thus preventing profile loss while maintaining USB connection flexibility.
