基于音频多模态研究的信号分析系统设计

Design of Signal Analysis System Based on Audio Multimodal Research

通过统计分析NSP模态文件准确定位真实数据,解析WAV模态文件结构、编码特征和影响因素,充分考虑声道数、采样频率、PCM采样位数,实现不同模态格式转换,设计基于音频多模态研究的信号分析系统。实验从文件内码、文件参数信息、信号声波波形和主观听觉感受方面进行综合对比分析,验证该系统的有效性和实用性。

This paper accurately locates real data through statistical analysis of NSP mode files,analyzes the structure,encoding features,and influencing factors of WAV mode files;fully considers the number of channels,sampling frequency,and PCM sampling bits to realize the conversion of different mode formats,and designs a signal analysis system based on audio multimodal research.The experiment conducts a comprehensive comparative analysis from the aspects of file internal code,file parameter information,signal acoustic waveform and subjective auditory perception to verify the effectiveness and practicality of the system.
