Real-time Spectral Analyzer/Filter
In general regenerating sound from frequency spectra takes
considerable time when the amount of frequency spectra is great due to deal with the convolution calculation. The method used in the spectral analyzer introduce in the following site: http://www.geocities.com/square17320...ad/ferftad.htm does not use the convolution for Fourier transform. So the efficiency of DFT is improved and it makes the real time Fourier transform and its inverse transform more portable. |
