wavwrite writes .wav sound file wavwrite(y, wavfile) wavwrite(y, Fs, wavfile) wavwrite(y, Fs, nbits, wavfile) y real vector or matrix with entries in [-1,1]. wavfile string (The .wav extension is appended if no extension is given) Fs integer, frequency sampling in Hz. 22500 is the default value. nbits bit-depth 8, 16, 24, 32 bits. it describes the number of bits of information recorded for each sample. 16 is the default value. Utility function to save .wav sound file. wavwrite(y,wavfile) writes a sound file specified by the string wavfile. The data should be arranged with one channel per column. Amplitude values outside the range [-1,+1] are ignored. wavwrite(y,Fs,wavfile) specifies in Fs the sample rate of the data in Hertz. auread wavread savewave analyze mapsound
