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.
34 All other wavefront_* types end up aligned to 32 bit values and
35 still have the same (correct) size.
37 #else
39 /* However, note that as of G++ 2.7.3.2, g++ was unable to
40 correctly parse *type* __attribute__ tags. It will do the
41 right thing if we use the "packed" attribute on each struct
42 member, which has the same semantics anyway.

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.
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:
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
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 ...
