Title:
The method for processing audio data, a device, and a system
Document Type and Number:
Japanese Patent JP6072068
Kind Code:
B2
Abstract:
The present invention discloses a method, an apparatus, and a system for processing audio data, and pertains to the field of communications technologies. The method includes: obtaining a noise frame of an audio signal, and decomposing the current noise frame into a noise low-band signal and a noise high-band signal; and encoding and transmitting the noise low-band signal by using a first discontinuous transmission mechanism, and encoding and transmitting the noise high-band signal by using a second discontinuous transmission mechanism. According to the present invention, different processing manners are used for the high-band signal and the low-band signal, calculation complexity may be reduced and encoded bits may be saved under a premise of not lowering subjective quality of a codec, and bits that are saved may help to achieve an objective of reducing a transmission bandwidth or improving overall encoding quality.
