Dynamic loudness normalization method for audio signals
The patent application (Publication Number: US20240039499A1) describes a loudness normalization method for audio signals based on a target loudness value. The method involves determining dynamic gain parameters for audio frames based on short-term and long-term characteristics of the audio signal. These parameters are used to modify the loudness of each frame to ensure consistency with the target loudness. The long-term characteristic is distinguished from the short-term characteristic in the determination process. Additionally, the dynamic gain parameters can be identified and applied in real-time, and various enhancements such as dialog enhancement, loudness equalization, and parameter smoothing can be applied to improve playback quality and tonal balance.
Furthermore, the patent application also includes an audio processing apparatus and a program storage device that implement the loudness normalization method. The apparatus consists of at least one processor and memory storing a computer program to determine dynamic gain parameters based on short-term and long-term characteristics of the audio signal. The program storage device contains instructions for executing operations related to modifying the loudness of audio frames to align with the target loudness value. Overall, the invention aims to provide a comprehensive solution for loudness normalization in audio signals, ensuring consistent playback quality and tonal balance while considering both short-term and long-term characteristics of the audio content.
