METHOD, APPARATUS AND SYSTEM FOR ENHANCING MULTI-CHANNEL AUDIO IN A DYNAMIC RANGE REDUCED DOMAIN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20230178084 titled 'METHOD, APPARATUS AND SYSTEM FOR ENHANCING MULTI-CHANNEL AUDIO IN A DYNAMIC RANGE REDUCED DOMAIN
Simplified Explanation
The patent application describes a method for generating an enhanced multi-channel audio signal from an audio bitstream using a generative adversarial network.
- The method enhances the two or more channels of the audio signal in a dynamic range reduced domain.
- A multi-channel generator in a generative adversarial network setting is used to jointly enhance the channels.
- The patent application also includes a method for training the multi-channel generator in the dynamic range reduced domain.
- An apparatus, systems, and a computer program product are also described for generating the enhanced multi-channel audio signal.
Potential Applications
This technology has potential applications in various fields, including:
- Audio production and post-production: Enhancing the audio quality of multi-channel recordings.
- Virtual reality and gaming: Providing immersive and realistic audio experiences.
- Broadcasting and streaming: Improving the audio quality of multi-channel content for viewers.
Problems Solved
The technology addresses the following problems:
- Limited dynamic range: Enhancing the audio signal in a dynamic range reduced domain allows for better control and manipulation of the audio levels.
- Inconsistent audio quality: The method ensures that all channels of the multi-channel audio signal are enhanced together, resulting in a more balanced and coherent audio experience.
- Computational efficiency: The use of a generative adversarial network allows for efficient training and generation of the enhanced multi-channel audio signal.
Benefits
The technology offers several benefits, including:
- Improved audio quality: The method enhances the audio signal, resulting in a more immersive and enjoyable listening experience.
- Efficient processing: By jointly enhancing the channels, the method reduces the computational complexity compared to processing each channel individually.
- Flexibility and control: The dynamic range reduced domain allows for precise control over the audio levels, enabling fine-tuning and customization of the enhanced audio signal.
