Different between WORLD fft and SPTK fftr? #133

Closed OnceJune closed 2 years ago

Hi I tried to compare fft real forward functions between WORLD and SPTK and found they give different result. In my understanding the should do the samething, is there any different between these to libraries?

Sorry, I didn't use SPTK's FFT function and used Ooura's FFT library in WORLD. I have implemented a simple wrapper to give compatibility with FFTW. So I don't know the difference between them. On the other hand, I have checked that result is not different between FFTW and Ooura's FFT functions.
