VOLUME LEVELER CONTROLLER AND CONTROLLING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240039499 titled 'VOLUME LEVELER CONTROLLER AND CONTROLLING METHOD
Simplified Explanation
The abstract describes a volume leveler controller and controlling method for adjusting the volume level of an audio signal based on its content type. The controller includes an audio content classifier that identifies the content type of the audio signal in real time, and an adjusting unit that continuously adjusts the volume leveler based on the identified content type.
- The volume leveler controller includes an audio content classifier for real-time identification of the content type of an audio signal.
- An adjusting unit is present to continuously adjust the volume leveler based on the identified content type.
- The dynamic gain of the volume leveler is positively correlated with informative content types of the audio signal.
- The dynamic gain of the volume leveler is negatively correlated with interfering content types of the audio signal.
Potential applications of this technology:
- Audio and video streaming platforms can use this technology to automatically adjust the volume level of different types of content, ensuring a consistent and optimal listening experience for users.
- Broadcasting companies can utilize this technology to maintain a balanced volume level across various programs and advertisements.
- In-car entertainment systems can benefit from this technology by automatically adjusting the volume level based on the type of audio content being played.
Problems solved by this technology:
- Inconsistent volume levels in audio content can be addressed, providing a more enjoyable listening experience.
- The need for manual adjustment of volume levels based on content type is eliminated, saving time and effort.
- Interference caused by sudden volume changes between different types of audio content is minimized.
Benefits of this technology:
- Users can enjoy a consistent volume level across different types of audio content, enhancing the overall listening experience.
- Automatic adjustment of volume levels based on content type eliminates the need for manual intervention.
- Minimizing interference caused by sudden volume changes improves the quality and clarity of audio playback.
Original Abstract Submitted
volume leveler controller and controlling method are disclosed. in one embodiment, a volume leveler controller includes an audio content classifier for identifying the content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner based on the content type as identified. the adjusting unit may configured to positively correlate the dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.
