11    # The following is the libtool / shared library version. This doesn't have to
12    # do anything with the release version. It MUST conform to the following rules:
13    #
14    #  1. Start with version information of `0:0:0' for each libtool library.
15    #  2. Update the version information only immediately before a public release of
16    #     your software. More frequent updates are unnecessary, and only guarantee
17    #     that the current interface number gets larger faster.
18    #  3. If the library source code has changed at all since the last update, then
19    #     increment revision (`c:r:a' becomes `c:r+1:a').
20    #  4. If any interfaces have been added, removed, or changed since the last update,
21    #     increment current, and set revision to 0.
22    #  5. If any interfaces have been added since the last public release, then increment
23    #     age.
24    #  6. If any interfaces have been removed since the last public release, then set age
25    #     to 0.

929                                  Uses integer math without any branch will then be
930                                  converted to floating point value for each sample point.
931                                  This int->float conversion might hurt on some systems.
932                                intmathabs:
933                                  Similar to intmath but uses abs() function.
934                                  Depending on compiler and platrofm this could
935                                  perform better than integer math as it avoids
936                                  an extra integer multiply instruction.
937                                diharmonic:
938                                  The triangular wave will be approximated by adding two
939                                  sinusoidials. This solution might especially hurt on
