annotate src/libmad-0.15.1b/sf_table.dat @ 83:ae30d91d2ffe

Replace these with versions built using an older toolset (so as to avoid ABI compatibilities when linking on Ubuntu 14.04 for packaging purposes)

Chris@0 23 * These are the scalefactor values for Layer I and Layer II.
Chris@0 24 * The values are from Table B.1 of ISO/IEC 11172-3.
Chris@0 25 *
Chris@0 26 * There is some error introduced by the 32-bit fixed-point representation;
Chris@0 27 * the amount of error is shown. For 16-bit PCM output, this shouldn't be
Chris@0 28 * too much of a problem.
Chris@0 29 *
Chris@0 30 * Strictly speaking, Table B.1 has only 63 entries (0-62), thus a strict
Chris@0 31 * interpretation of ISO/IEC 11172-3 would suggest that a scalefactor index of
Chris@0 32 * 63 is invalid. However, for better compatibility with current practices, we
Chris@0 33 * add a 64th entry.
