Fast Fourier Transform Convolution Reverb (FFTC) of audio signals C code -- 2

I need to make a C program for FFT Convolution of Audio files to provide reverberation (FFT Convolution Reverb) and need to implement that code on desktop software. Program should perform in the following manner: It should read the impulse response saved on the computer and should combine it with input audio signal using FFT Convolution. Main aim is to make a C Program for FFT Convolution Reverb and heavily comment every statement with scientific proofs supporting the comments. Comments should be accurate based on theory of FFT and Convolution which can be used in my report to help write a theory of 7-8 pages. Program Should be 100% Plagiarism free and all references should be mentioned from where any advise is taken.
