Read NeXT/SUN (
.au) sound file
As an alternative to
auread, use the Import Wizard. To activate the Import Wizard, select Import data from the File menu.
y = auread('aufile')
loads a sound file specified by the string
aufile, returning the sampled data in
.au extension is appended if no extension is given. Amplitude values are in the range
auread supports multi-channel data in the following formats:
[y,Fs,bits] = auread('aufile')
returns the sample rate (
Fs) in Hertz and the number of bits per sample (
bits) used to encode the data in the file.
[...] = auread('aufile',N)
returns only the first
N samples from each channel in the file.
[...] = auread('aufile',[N1 N2])
returns only samples
N2 from each channel in the file.
siz = auread('aufile','size')
returns the size of the audio data contained in the file in place of the actual audio data, returning the vector
siz = [samples channels].
