Method and System for Encoding Loudness Metadata of Audio Components - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240105196 titled 'Method and System for Encoding Loudness Metadata of Audio Components
Simplified Explanation
The patent application describes a method for encoding audio signals with metadata related to loudness levels.
- Receiving an audio component with an audio signal
- Determining the loudness level of the audio component
- Receiving a target loudness level for the audio component
- Encoding the audio signal into a bitstream with metadata including the loudness level and target loudness level
- Transmitting the bitstream to an electronic device
Potential Applications
This technology could be applied in audio streaming services, broadcasting, and audio production tools.
Problems Solved
This technology solves the problem of inconsistent loudness levels in audio content, ensuring a more uniform listening experience for users.
Benefits
The benefits of this technology include improved audio quality, better user experience, and compliance with loudness standards.
Potential Commercial Applications
A potential commercial application of this technology could be in the development of audio encoding software for media companies.
Possible Prior Art
One possible prior art could be the use of metadata in audio files to store information about the audio content, including loudness levels.
Unanswered Questions
How does this method handle dynamic range compression in audio signals?
The patent application does not specify how dynamic range compression is addressed in the encoding process.
What impact does encoding with metadata have on file size and streaming bandwidth?
The patent application does not discuss the potential effects of adding metadata to audio bitstreams on file size and streaming requirements.
Original Abstract Submitted
a method that includes receiving an audio component associated with an audio scene, the audio component including an audio signal, determining a loudness level of the audio component based on the audio signal, receiving a target loudness level for the audio component, producing a bitstream with the audio component by encoding the audio signal and including metadata that has the loudness level and the target loudness level, and transmitting the bitstream to an electronic device.
