c@0: function [y,fs,bits] = wavread(filename,arg)
c@0: %WAVREAD Read an audio file
c@0: % 
c@0: %   WAVREAD is a wrapper function for audioread, using the same function
c@0: %   name and input arguments as the deprecated MATLAB WAVREAD function. It
c@0: %   is provided in order to improve the compatibility of legacy code.
c@0: %   
c@0: %   Y = WAVREAD(FILENAME) loads an audio file specified by the string
c@0: %   FILENAME, returning the sampled data in Y. Audio channels are returned
c@0: %   in the columns of Y.
c@0: % 
c@0: %   [Y,FS,BITS] = WAVREAD(FILENAME) returns the sample rate (FF) in Hertz
c@0: %   and the number of bits per sample (BITS) used to encode the data in the
c@0: %   file.
c@0: % 
c@0: %   ... = WAVREAD(FILENAME,N) returns only the first N samples from each
c@0: %   channel in the file.
c@0: % 
c@0: %   ... = WAVREAD(FILENAME,[N1 N2]) returns only samples N1 through N2 from
c@0: %   each channel in the file.
c@0: %   
c@0: %   SIZ = WAVREAD(FILENAME,'SIZE') returns the size of the audio data
c@0: %   contained in the file in place of the actual audio data, returning the
c@0: %   vector SIZ = [NumSamples NumChannels].
