@ -360,8 +360,10 @@ results with audio data files which are :
little-endian byte order with option -swab
Files with name extension .wav get examined wether they are in Microsoft WAVE
format with above parameters and eventually get extracted by cdrskin itself.
All other formats (including SUN's format .au) are to be extracted by commands
like those given above under "Usage examples".
Files with name extension .au get examined wether they are in SUN's audio
format with above parameters. Their big-endianness gets handled properly.
Any other formats are to be extracted by commands like those given above under
"Usage examples".
I myself am not into audio. So libburn-hackers@pykix.org might be the
best address for suggestions, requests and bug reports.
