auread — load .au sound file
y=auread(aufile) y=auread(aufile,ext) [y,Fs,bits]=auread(aufile) [y,Fs,bits]=auread(aufile,ext)
| aufile | : string (The .au extension is appended if no extension is given) |
| Fs | ... |
| [] | : integer, frequency sampling in Hz. |
| ext | : string ('size' or 'snd') or integer (to read n samples) or 1 x 2 integer vector [n1,n2] (to read from n1 to n2). |
Utility function to read .au sound file. auread(aufile) loads a sound file specified by the string aufile, returning the sampled data in y. Amplitude values are in the range [-1,+1].
Supports multi-channel data in the following formats: 8-bit mu-law, 8-, 16-, and 32-bit linear, and floating point.
[y,Fs,bits]=auread(aufile) returns the sample rate (Fs) in Hertz and the number of bits per sample used to encode the data in the file.
auread(aufile,n) returns the first n samples from each channel.
auread(aufile,[n1,n2]) returns samples n1 to n2.
auread(aufile,'size') returns the size of the audio data contained in the file in place of the actual audio data, returning the vector as [samples channels].
auread(aufile,'snd') returns information about the sample and data as a tlist.
