Problems solved by technology

[0004] However, the existing multi-description coding is based on the processing at the signal source level. When deploying the encoder, it is necessary to completely replace the existing single-description encoder with the multi-description encoder, resulting in significant problems such as encoding compression efficiency, voice quality, and bandwidth occupation. Influence, and then affect the encoding effect of the audio signal

Abstract

The invention relates to an audio coding method and device, an audio decoding method and device, equipment, a storage medium and a product, and relates to the technical field of network communication. The method comprises the following steps: acquiring a first audio signal frame; encoding the first audio signal frame to obtain encoding parameters of the first audio signal, the encoding parameters including a whole frame type parameter and a framing type parameter; grouping the framing parameters to obtain n parameter groups; the parameter group comprises framing class parameters of at least one subframe corresponding to the parameter group, n is greater than or equal to 2, and n is a positive integer; respectively combining the whole frame type parameters with the n parameter groups to generate n description coding code streams corresponding to the n parameter groups; according to the method, single description coding equipment is transformed into multi-description coding equipment, so that the coding mode is changed from single description coding to multi-description coding, and the coding effect of the audio signal is improved while the packet loss resistance is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of network communication technologies, and in particular to an audio encoding method, decoding method, device, equipment, storage medium, and product. Background technique [0002] With the development of communication technology, the audio codec scheme has become an important technical means of audio communication. However, in the actual operation of real-time audio communication, due to factors such as network congestion, channel interference and noise, unavoidable packet loss problems have greatly affected calls. audio quality. [0003] In the related art, a multiple description coding (MDC, Multiple Description Coding) technology is used to solve the problem of quality degradation caused by audio coding transmission packet loss. Among them, the multi-description coding technology is a technology that uses different decomposition methods to separate the original signal, and uses differe...
