0f66d2c701 COMMON: Update DCT & RDFT to avoid dynamic allocation of Sine/Cos Tables. 2012-04-17 22:12:20 +01:00

f4ba8a6485 COMMON: Replaced static Sine and Cosine tables with dynamic generated. 
This removes the large static tables from the binary (which saves 500K
to 1Mb of binary size) and replaced them with a class which generates
the required tables as needed in RAM. This has been tested with QDM2
and shows no obvious performance degredation and Memprof shows no
significant rise in RAM usage.
