Abstract

The invention discloses an equalizer controller and a control method. In one embodiment, the equalizer controller includes an audio classifier for identifying the audio type of an audio signal in real time; and an adjusting unit for adjusting an equalizer in a continuous manner based on the confidence value of the audio type as identified.

Description

Technical field [0001] This application relates generally to audio signal processing. Specifically, the embodiments of the present application relate to devices and methods for audio classification and audio processing, in particular to the control of a dialog enhancer, a surround sound virtualizer, a volume leveler, and an equalizer. 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 the spectral domain. Various audio improvement 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. In order to improve its clarity and comprehensibility, especially for the elderly with hearing loss, methods to enhance dialogue have been develope...
