Description

This block writes a sound file specified by the string *.au file. The data should be arranged with one channel per column. Amplitude values outside the range [-1,+1] are clipped prior to writing. auwrite supports multichannel data for 8-bit mu-law and 8- and 16-bit linear formats.

Dialog box

• 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
