algorithm - Audio Processing C++ - FFT - Stack Overflow
https://stackoverflow.com/questions/11851245/audio-processing-c-fft
The FFT in Numerical Recipes in C uses the Cooley-Tukey Algorithm, so in answer to your question at the end, the int sign being passed allows the same routine to be used to compute both the forward (sign=-1) and inverse (sign=1) FFT. This seems to be consistent with the way you are using sign when you define theta = sign * (2*pi/mmax).

The audio processing algorithms implemented in this application note are: • Distortion Unit (Distortion.c): distortion is the effect obtained by increasing the range of the signal, so that the non-linearities of the amplifier are stimulated resulting in clipping of the signal peaks and in an

xc, as follows: xd[n] = xc(nTs) −∞ < n < ∞, (1.1) The quantity Ts is called sampling period, measured in s. Its its reciprocal is the sampling frequency, measured in Hz, and is usually denoted as F s= 1/T. Note also the use of square brackets in the notation for a discrete-time signal x[n], which avoids ambiguity with the notation x(t) used for a
Learning to work with audio in C++ - Stack Overflow

Re C vs C++, I think you'll find that in audio work, the C++ part is often really just chrome for code management. The DSP bits are all low level procedural math on signals, so it's likely to be C calls and it really doesn't matter for that side of things whether you use C or C++. A lot of C++ audio projects are essentially just C in the audio ...
