 Set number of channels for raw input (default: 2)

 .IP "--raw-endianness [0/1]"

 Set the endianness for raw input: 1 for bigendian, 0 for little (defaults to 0)

+.IP "--ignorelength"

+Always ignore the datalength in Wave headers. Opusenc automatically ignores

+the length when its implausible (very small or very large) but some STDIN

+usage may still need this option to avoid truncation.
