13      You will not be able to compile this file correctly without gcc, because
14      it is necessary to pack the "wavefront_alias" structure to a size
15      of 22 bytes, corresponding to 16-bit alignment (as would have been
16      the case on the original platform, MS-DOS). If this is not done,
17      then WavePatch-format files cannot be read/written correctly.
18      The method used to do this here ("__attribute__((packed)") is
19      completely compiler dependent.
20 
21      All other wavefront_* types end up aligned to 32 bit values and
22      still have the same (correct) size.

29 	member, which has the same semantics anyway.

384   Because most/all of the sample data we pass in via pointers has
385   never been copied (just mmap-ed into user space straight from the
386   disk), it would be nice to allow handling of multi-channel sample
387   data without forcing user-level extraction of the relevant bytes.
388 
389   So, we need a way of specifying which channel to use (the WaveFront
390   only handles mono samples in a given slot), and the only way to do
391   this without using some struct other than wavefront_sample as the
392   interface is the awful hack of using the unused bits in a
393   wavefront_sample:
394 
395   Val      Meaning
396   ---      -------
397   0        no channel selection (use channel 1, sample is MONO)
398   1        use first channel, and skip one
399   2        use second channel, and skip one
400   3        use third channel, and skip two
401   4        use fourth channel, skip three
402   5        use fifth channel, skip four
403   6        use six channel, skip five
404 
405 
406   This can handle up to 4 channels, and anyone downloading >4 channels
407   of sample data just to select one of them needs to find some tools
408   like sox ...
