C++ FFT
C++ radix 2 & 3 multi-dimension complex FFT & graphical test program
This C++ code does radix 2 & 3 multi-dimension (any) complex FFT and its inverse. Array dimensions with sizes that are not 2^m 3^n are automatically zero-padded to the nearest larger size integer of the form 2^m 3^n. The new array has the original data centered, except when a dimension size is increased by an odd number, the zero padding on the left is one less than the zero padding on the right. -

PerfectSineWaves
Perfect and bit-perfect PCM encoded sine wave audio test tones
...Because most audio players don't loop cleanly, the included wave files contain enough complete patterns to play 2 minutes without looping. Every sinusoid in the file contains a whole number of cycles. This ensures clean looping and allows windowless FFT analysis. Each sinusoid in the file can have a unique phase and amplitude. The included wave file generation utility uses GNU MPFR library for extended precision floating point math and FFTW for verification. Output level is nearest possible to 0 dBTP without going over. -
