Audio Output Device with Hardware Volume Control - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240303033 titled 'Audio Output Device with Hardware Volume Control
Simplified Explanation: The patent application describes a method performed by an audio source device connected to an audio output device. The method involves adjusting the volume of an audio signal, applying dynamic range compression, and then transmitting the compressed audio signal to the output device.
- Obtaining an audio signal
- Receiving a volume adjustment
- Applying the volume adjustment to the audio signal
- Applying dynamic range compression to the volume-adjusted audio signal
- Applying an inverse volume adjustment to the compressed audio signal for transmission to the output device
Key Features and Innovation: - Volume adjustment of audio signal - Dynamic range compression - Inverse volume adjustment for transmission - Improved audio quality and consistency
Potential Applications: This technology can be used in audio devices such as speakers, headphones, and sound systems to enhance the listening experience by maintaining consistent audio levels.
Problems Solved: - Inconsistent audio levels - Lack of dynamic range control - Poor audio quality due to volume fluctuations
Benefits: - Enhanced audio quality - Consistent volume levels - Improved listening experience
Commercial Applications: Title: "Enhanced Audio Control Technology for Audio Devices" This technology can be applied in consumer electronics, professional audio equipment, and entertainment systems to provide users with a more enjoyable and consistent audio experience. It can be marketed as a feature that ensures optimal audio performance in various settings.
Prior Art: Prior art related to this technology may include patents or research on audio signal processing, dynamic range compression, and volume control in audio devices.
Frequently Updated Research: Researchers are continually exploring new methods and algorithms for audio signal processing and dynamic range compression to further improve audio quality and user experience.
Questions about Audio Signal Processing: 1. How does dynamic range compression impact the audio signal? Dynamic range compression reduces the difference between loud and soft sounds in an audio signal, resulting in a more balanced and consistent output. 2. What are the key considerations when implementing volume adjustments in audio devices? Volume adjustments in audio devices should be carefully calibrated to ensure optimal sound quality and user experience.
Original Abstract Submitted
a method performed by an audio source device that is communicatively coupled with an audio output device, the method includes obtaining an audio signal; receiving a volume adjustment; applying the volume adjustment to the audio signal; applying dynamic range compression on the volume adjusted audio signal; and applying an inverse volume adjustment to the compressed audio signal, where the inverse volume adjusted audio signal is to be transmitted to the audio output device.
