Abstract: In allusion to the requirements of high data volume, low power consumption and high real-time performance faced in multi-track digital audio signal transmission, a low-power and high-speed transmission method based on the low-power DSP hardware platform is researched. The optimized G.723.1 dual-rate encoding algorithm is used to compress and encode the initial multi track digital audio signal, reducing data redundancy. By using an improved LMS adaptive filtering algorithm based on skip tongue line variable step size and decorrelation operation, the noise of the encoded audio signal is dynamically filtered out to enhance the quality of the audio signal. The embedded Socket communication based on UDP protocol is used to realize the high-speed real-time transmission of encoded and filtered audio signals by means of local area network. After decoding and reconstruction at the signal receiving end, the output can directly play audio data. Taking the multi track sampling audio signal of Zeng Houyi chime bell as an example in the experiment, the results show that this method can effectively filter out noise in the signal and ensure the quality of transmitted signals. When the amount of transmitted audio data reaches 1000 MB, the total power consumption is only 37.8 J, which can meet the requirement of low-power transmission for large data volumes.
