wavread
Read Microsoft WAVE (.wav) sound file
y = wavread('filename')
[y,Fs,bits] = wavread('filename')
[...] = wavread('filename',N)
[...] = wavread('filename',[N1 N2])
[...] = wavread('filename','size')
wavread supports multichannel data, with up to 16 bits per sample.
y = wavread('filename')
loads a WAVE file specified by the string filename, returning the sampled data in y. The .wav extension is appended if no extension is given. Amplitude values are in the range [-1,+1].
[y,Fs,bits] = wavread('filename')
returns the sample rate (Fs) in Hertz and the number of bits per sample (bits) used to encode the data in the file.
[...] = wavread('filename',N)
returns only the first N samples from each channel in the file.
[...] = wavread('filename',[N1 N2])
returns only samples N1 through N2 from each channel in the file.
siz = wavread('filename','size')
returns the size of the audio data contained in the file in place of the actual audio data, returning the vectorsiz = [samples channels].
