### 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
