The embodiment of the invention provides a multi-channel audio compression and decompression method. The method comprise the steps of receiving a multi-channel audio file, determining the
audio frequency, the number of channels, and the arrangement sequence of each channel of the multi-channel audio file; splitting the multi-channel audio file according to the number of channels, carrying out framing on the split audio channel audio according to the
audio frequency, and inputting the split audio file into a speex compression engine for compression to obtain an ogg compressed packet of each channel of audio separately; and alternately storing the ogg compressed packet of each channel of audio according to the arrangement sequence of each channel to generate the compressed file of the multi-channel audio. The embodiment of the invention also provides a multi-channel audio compression and decompression
system. According to the embodiments of the invention, in the compression process, alternate storage is performed according to the sequence of the channels, preparation is carried out for the decoding process, and the multi-channel parallel decoding can be carried out during decoding, so that the
delay in the multi-channel audio transmission is reduced, and the problem of
delay caused by demand and transmission data on the network bandwidth by
the Internet of Things equipment is reduced.
