| RESPITE: The CASA Toolkit Page: Documentation: Block Library Index: AUInputFile |
Read sample data from a AU format file. The file name is supplied as a parameter. A file path and file extension may also be supplied.
Two AU formats are supported: 16-bit linear and 8-bit 
-law. The format is determined from the file header. The header also determines whether the data is mono or stereo. In the case of stereo data, the block will make for itself a separate output socket for each channel - the left channel is sent to out1 and the right channel to out2.
