The invention discloses a network
audio mixing processing method and device, relating to the technical field of audio
processing. The method comprises a step of performing symbolic accumulation on each audio data, a step of performing segmented compression on the accumulated audio data, a step of determining an
attenuation factor of each segment, and a step of acquiring an outputted mixed
audio signal. According to the mixing
processing method, the method of segmental compression is employed for mixing, that is, the operation efficiency is high, and the mixing is easy to realize in a single-
chip microcomputer. Through the actual
waveform observation, the method is synthesized, there is no overflow and
topping phenomenon after obtaining the mixed sound of the method, the data is compressednear upper and lower limits, the volume is large, the remaining intelligibility is high, and there is no obvious
noise interference in listening. A
system used in the device of the present invention can realize the function by only using the single-
chip microcomputer with an ARMCortexTM-M4 architecture or higher, an existing LWIP
protocol stack, the
system can support the basic
transmission protocol in TCP / IP, since only one single-
chip microcomputer for processing is required, an FPGA can be omitted from a circuit, and therefore, the cost is saved.
