请问我这个问题要怎么解决？显示我未定义函数或变量 ，wavrecord和wavread都现显示的未定义？

Answer 1

同学你好！wavrecord和wavread都是matlab 2015b以及之前版本的函数，之后的matlab版本已经把这两个函数移除了，取而代之的是audiorecorder和audioread两个函数。用法分别如下：

recorder = audiorecorder(Fs,nBits,NumChannels) 设置采样率 Fs（以赫兹为单位）、采样位数 nBits 和通道数 nChannels。
[x, fs] = audioread('c:\matlab\work\waed.wav');    

可以自己看文档，知道用法。

Object for recording audio - MATLAB Use an audiorecorder object to record audio data from an input device such as a microphone for processing in MATLAB. https://www.mathworks.com/help/matlab/ref/audiorecorder.html

Read audio file - MATLAB audioread This MATLAB function reads data from the file named filename, and returns sampled data, y, and a sample rate for that data, Fs. https://www.mathworks.com/help/matlab/ref/audioread.html
