Description

Loads a sound file specified by the string *.au file, 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:

• 8-bit mu-law
• 8-, 16-, and 32-bit linear
• Floating-point

Dialog box

• Input file name a character string defining the path of the file. Properties : Type ‘str’ of size 1
• Buffer size To improve efficiency it is possible to buffer the input data. Read on the file is only done after each Buffer size call to the block. Properties : Type ‘vec’ of size 1
• Swap mode 0/1 With Swap mode=1 the file is supposed to be coded in “little endian IEEE format” and data are swaped if necessary to match the IEEE format of the processor. If Swap mode=0 then automatic bytes swap is disabled. Properties : Type ‘vec’ of size 1

Default properties

• always active: no
• direct-feedthrough: no
• zero-crossing: no
• mode: no
• regular outputs: - port 1 : size [1,1] / type 1
• number/sizes of activation inputs: 1
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: yes
• object discrete-time state: no
• name of computational function: readau
