| Dec 12, 2012 at 10:10 | comment | added | mrgloom | I want to check my fft implementation works just like original implementation and I want to do performance comparision.Also maybe it will be simpler to parallelize code without fft. | |
| Dec 12, 2012 at 9:56 | comment | added | Zigner | hmm. Had to go read the source. You are correct it does use fft. Just curious, why is that a limitation? | |
| Dec 12, 2012 at 9:56 | comment | added | Naresh | Why would you not want to use FFT? Its just a faster implementation of DFT and shows no performance or quality loss. Is this a homework problem? | |
