Problems solved by technology
[0004] However, in practical applications, it often happens that although the source encoding of the sender uses a higher bit rate and higher sampling rate to make the source encoding quality higher, the receiver cannot hear the voice of the sender clearly, and even cannot recognize the sound quality. Bad, the conversion efficiency of such encoding quality is low, and the effect of voice communication is not good

The embodiments of the invention disclose a methodand device for regulating and controlling coding parameters, equipment and a storage medium. The method includes the steps that a first audio signal recorded by a transmitting terminal isacquired, and a psychoacoustic masking threshold value of each frequency point in a service frequency band of the first audio signal isdetermined; a second audio signal recorded by a receiving terminal isacquired, a background environmental noise estimation value of each frequency point in the service frequency band of the second audio signalis determined; and a masking mark corresponding to each frequency point in the service frequency band is determined according to the psychoacoustic masking threshold value of the first audio signal and the background environmental noise estimation value of the second audio signal; a masking rate of the service frequency band isdetermined according to the masking mark corresponding to each frequency point in the service frequency band; a first reference code rateisdetermined according to the masking rate of the service frequency band; and at least based on the first reference code rate, the coding rate of an audio encoder isconfigured. According to the method, the coding quality conversion efficiency can be effectively improved,and a good voice communication effect between the transmitting terminal and the receiving terminal is ensured.
Description
technical field [0001] The present application relates to the technical field of audio coding, and in particular to a coding parameter control method, device, device and storage medium. Background technique [0002] Audio coding is the process of taking sound from the form of energy waves through a series of processes to generate digital codes. Audio coding is to ensure that the sound signal occupies a small transmission bandwidth and storage space during transmission and can ensure high sound quality. [0003] In practical applications, audio signals are usually encoded based on an audio encoder, and the encoding quality mainly depends on whether the encoding parameters configured by the audio encoder are appropriate. Based on this, in order to pursue better encoding quality, existing technical solutions usually adaptively configure encoding parameters based on device processing capabilities and network bandwidth characteristics during audio encoding, such as configuring h...
