333   Because most/all of the sample data we pass in via pointers has
334   never been copied (just mmap-ed into user space straight from the
335   disk), it would be nice to allow handling of multi-channel sample
336   data without forcing user-level extraction of the relevant bytes.
337 
338   So, we need a way of specifying which channel to use (the WaveFront
339   only handles mono samples in a given slot), and the only way to do
340   this without using some struct other than wavefront_sample as the
341   interface is the awful hack of using the unused bits in a
342   wavefront_sample:
343 
344   Val      Meaning
345   ---      -------
346   0        no channel selection (use channel 1, sample is MONO)
347   1        use first channel, and skip one
348   2        use second channel, and skip one
349   3        use third channel, and skip two
350   4        use fourth channel, skip three
351   5        use fifth channel, skip four
352   6        use six channel, skip five
353 
354 
355   This can handle up to 4 channels, and anyone downloading >4 channels
356   of sample data just to select one of them needs to find some tools
357   like sox ...
