Shifts audio channels 0 and 1 up channels, based on the offset value
&channeloffsetshifts audio channels 0 and 1 up channels, based on the offset value you set.
Total channels is assumed to be 8 if this is used and not otherwise specified.
Does not work with all audio output devices and may require experimentation.
Best to use this with a mono input, as stereo channel shifting can cause issues - simpler that way.
