wavread - Read WAVE (.wav) sound file

    This MATLAB function loads a WAVE file specified by the string filename,     returning the sampled data in y.

    y = wavread(filename)     [y, Fs] = wavread(filename)     [y, Fs, nbits] = wavread(filename)     [y, Fs, nbits, opts] = wavread(filename)     [___] = wavread(filename, N)     [___] = wavread(filename, [N1 N2])     [___] = wavread(___, fmt)     siz = wavread(filename,'size')

audioread - Read audio file

    This MATLAB function reads data from the file named filename, and returns     sampled data,y, and a sample rate for that data, Fs.

    [y,Fs] = audioread(filename)     [y,Fs] = audioread(filename,samples)     [y,Fs] = audioread(___,dataType)

wavwrite - Write WAVE (.wav) sound file

    This MATLAB function writes the data stored in the variable y to a WAVE file     called filename.

    wavwrite(y,filename)     wavwrite(y,Fs,filename)     wavwrite(y,Fs,N,filename)

audiowrite - Write audio file

    This MATLAB function writes a matrix of audio data, y, with sample rate Fs to a     file called filename.

    audiowrite(filename,y,Fs)     audiowrite(filename,y,Fs,Name,Value)

load ISM.mat filename = 'ISM.wav';

wavwrite(y,Fs,filename); audiowrite(filename,y,Fs);

以上是wavwrite函式，audiowrite函式區別
