罗志灵(033512038)_第二次作业（WAVE）
- wave编解码和波谱图-wave codec and spectrogram Proposed
formant_extract
- 声谱图+共振峰,有中文的注解, 像Praat-spectrogram+ Formant, Code has Chinese comments
VC_sound
- 实现音效的柱状频谱图效果,vc写的，研究音效很有帮助-Achieve sound columnar the spectrogram effect, vc written, sound helpful
SoundCatcher
- This project demonstrates an implementation of the waterfall spectrogram and use of statistical data to trigger events in near real-time. This code is an elaboration of my previous submission (SoundViewer). This demonstration utilizes the Wave classe
spectrogram
- This code generates the spectrogram of an input audio file.
soundchange
- 对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果-SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Li
Spectrogram
- show spectogram of wave file. It use FFT to draw spectrum of sound. only support saved wave file.
audioIO
- It reads a wave file, and shows the waveform/spectrogram.
matlab画语音语谱图
- 语谱图反映了语音信号的动态频谱特性，在语音分析中具有重要的实用价值，被称为可视语音。“yuputu”是用matlab完成语谱图的程序(Spectrogram reflects the dynamic spectrum characteristics of speech signals. It has important practical value in speech analysis and is called visual speech. "Yuputu" is a p
