2017-07-11avcodec/rdft: remove sintableMuhammad Faiz
It is redundant with costable. The first half of sintable is identical with the second half of costable. The second half of sintable is negative value of the first half of sintable. The computation is changed to handle sign of sin values, in C code and ARM assembly code. Signed-off-by: Muhammad Faiz <mfcc64@gmail.com>

2011-03-20Move dct and rdft definitions to separate filesMans Rullgard
This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>
