26      You will not be able to compile this file correctly without gcc, because
27      it is necessary to pack the "wavefront_alias" structure to a size
28      of 22 bytes, corresponding to 16-bit alignment (as would have been
29      the case on the original platform, MS-DOS). If this is not done,
30      then WavePatch-format files cannot be read/written correctly.
31      The method used to do this here ("__attribute__((packed)") is
32      completely compiler dependent.
33 
34      All other wavefront_* types end up aligned to 32 bit values and
35      still have the same (correct) size.

397   Because most/all of the sample data we pass in via pointers has
398   never been copied (just mmap-ed into user space straight from the
399   disk), it would be nice to allow handling of multi-channel sample
400   data without forcing user-level extraction of the relevant bytes.
401 
402   So, we need a way of specifying which channel to use (the WaveFront
403   only handles mono samples in a given slot), and the only way to do
404   this without using some struct other than wavefront_sample as the
405   interface is the awful hack of using the unused bits in a
406   wavefront_sample:
407 
408   Val      Meaning
409   ---      -------
410   0        no channel selection (use channel 1, sample is MONO)
411   1        use first channel, and skip one
412   2        use second channel, and skip one
413   3        use third channel, and skip two
414   4        use fourth channel, skip three
415   5        use fifth channel, skip four
416   6        use six channel, skip five
417 
418 
419   This can handle up to 4 channels, and anyone downloading >4 channels
420   of sample data just to select one of them needs to find some tools
421   like sox ...
