|Title: ||FFT Convolution Reverberation|
|Authors: ||Sjarif, Nathaniel|
|Issue Date: ||18-Apr-2012|
Convolution can be achieved in matlab in both the Time and Frequency Domain. The FFT convolution in matlab is ostensibly more efficient than it’s conv function counterpart.
Convolution in the Frequency domain using fft proves to be a lot more efficient than convolution in the time domain using the conv function in matlab. Using the conv function and the same two input files resulted in my computer crashing.
A mathematical analysis, utilizing coding within matlab has proven the efficiency and effectiveness of convolution reverberation in the frequency domain using transients in spaces as impulse responses.|
