Read NeXT/SUN (.au
) sound file
Graphical Interface
As an alternative to auread
, use the Import Wizard. To activate the Import Wizard, select Import data from the File menu.
Syntax
y = auread('aufile') [y,Fs,bits] = auread('aufile') [...] = auread('aufile',N) [...] = auread('aufile',[N1,N2]) siz = auread('aufile','size')
Description
y = auread('aufile')
loads a sound file specified by the string aufile
, returning the sampled data in y
. The .au
extension is appended if no extension is given. Amplitude values are in the range [-1,+1]
. auread
supports multichannel 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 N1
through 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]
.
