Volume leveler controller and controlling method

摘要

Volume leveler controller and controlling method are disclosed. In one embodiment, A volume leveler controller includes an audio content classifier for identifying the content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner based on the content type as identified. The adjusting unit may configured to positively correlate the dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.

主权项

1. A volume leveler controlling method comprising:
identifying the content type of an audio signal in real time; and adjusting a volume leveler in a continuous manner based on the content type as identified, by increasing or decreasing the dynamic gain of the volume leveler with, respectively, the increasing or decreasing of the confidence value of informative content types of the audio signal, and increasing or decreasing the dynamic gain of the volume leveler with, respectively, the decreasing or increasing of the confidence value of interfering content types of the audio signal; wherein the audio signal is classified into multiple content types with corresponding confidence values, and the adjusting operation is configured to consider at least some of the multiple content types through weighting the confidence values of the multiple content types based on the importance of the multiple content types and wherein the volume leveler controlling method is implemented at least partially in computer hardware.
