RFFT + IRFFT

This example shows how to load a WAV file from PC and apply windowing to the input samples. The functions to do RFFT and IRFFT are generated with Autotiler. Then the FFT and iFFT are computed on the cluster and the signal is reconstructed and saved in a file on the PC. The default values are 400 samples window size, 100 samples window step. The FFT is 512 points. To change the default values please check the variable in CMakeLists.txt.
