Abstract

The invention discloses a device and a method for audio classification and audio processing. In one implementation mode, the audio processing device comprises an audio classifier for classifying audio signals to at least one audio type in real time, an audio improving device for improving the experience of audiences and an adjusting unit for adjusting at least one parameter of the audio improving device based on a confidence value of at least one audio type in a continuous mode.

Description

technical field [0001] This application relates generally to audio signal processing. In particular, embodiments of the present application relate to devices and methods for audio classification and audio processing, and more particularly to controls for dialogue enhancers, surround virtualizers, volume levelers, and equalizers. Background technique [0002] In order to improve the overall quality of the audio and correspondingly improve the user experience, some audio improvement devices are used to modify the audio signal in the time domain or in the spectral domain. Various audio improving devices have been developed for various purposes. Some common examples of audio improvement devices include: [0003] Dialogue Enhancer: In movies and radio or TV shows, dialogue is the most important ingredient for understanding the story. To improve its intelligibility and its intelligibility, especially for elderly people with hearing loss, methods for enhancing dialogue were deve...
