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GUI界面上，实现语音读取，描绘时域波形和频域波形，并进行采样和冲采样，最后进行非均匀量化（13折线）！-GUI interface, voice read, depicting the time-domain waveform and frequency domain waveforms, and sampling and washed samples, the final non-uniform quantization broken line (13)

双线性变换法设计Butterworth滤波器。分别画出滤波前和滤波后的时域图和频谱图。-Bilinear transform design Butterworth filter. Draw the pre-filter and the filtered time-domain and frequency spectrum.

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
