这是一个基于matlab的短时傅里叶变换时频分析工具箱2-This is a matlab-based short-time Fourier transform time-frequency analysis toolbox

在matlab中利用声卡对语音信号进行实时采集，并采集波形图，对采集信号进行频谱分析，画出频谱图，能查找峰值频率。有详细的注释和参数调整说明-In Matlab using real- time audio of the speech signal acquisition and acquisition waveform, Spectral Analysis of Signals and draw the spectrum, can find the peak frequency.A detai
