回复：（飞扬）求wavwrite（）这个函数的具体参数

<P>helpwavwrite<BR><BR> WAVWRITE Write Microsoft WAVE (".wav") sound file.<BR>    WAVWRITE(Y,FS,NBITS,WAVEFILE) writes data Y to a Windows WAVE<BR>    file specified by the file name WAVEFILE, with a sample rate<BR>    of FS Hz and with NBITS number of bits.NBITS must be 8, 16,<BR>    24, or 32.Stereo data should be specified as a matrix with two <BR>    columns. For NBITS &lt; 32, amplitude values outside the range <BR>    [-1,+1] are clipped.<BR> <BR>    WAVWRITE(Y,FS,WAVEFILE) assumes NBITS=16 bits.<BR>    WAVWRITE(Y,WAVEFILE) assumes NBITS=16 bits and FS=8000 Hz.<BR> <BR>    8-, 16-, and 24-bit files are type 1 integer PCM.32-bit files <BR>    are written as type 3 normalized floating point.<BR> <BR>    See also WAVREAD, AUWRITE.</P>
