Analysis of Practical Application of Medium Wave Relay Station Based on Audio Contrast Monitoring
With the development of medium-wave relay station technology,the high-quality transmission and monitoring of audio signals become very important.Photoelectric conversion technology brings the advantages of high fidelity and low interference to signal transmission,but it may also encounter challenges in the transmission process,such as small interference caused by dielectric heterogeneity.Audio comparison monitoring technology can effectively monitor and ensure the accuracy and authenticity of broadcast content.Advanced algorithms such as Mel Frequency Cepstral Coefficients(MFCC)are used to analyze the signal quality.This paper mainly analyzes the function and principle of audio comparison monitoring and its application in medium wave relay station,in order to reduce human error and failure rate through audio monitoring on medium wave relay platform.
