This is a Program to generate power spectrum matched noise. This is primarily intended for audiologists to generate their own speech shaped noises based on existing speech Corpus (Multiple speech files). The input can be any number of wav files. The program derives the fourier transform of all the speech files put together. The Fourier transform thus obtained is then manipulated such that the phases of the spectral components are randomised. The resultant modified fourier output is then converted back into the time domain using an inverse fourier transform. The resultant is a speech shaped noise with spectrum almost identical to that of the original speech corpus.
