Abstract
A spectral sound synthesis algorithm based on threshold stochastic resonance is proposed theoretically and implemented in Matlab. The technique consists in the addition of a noise signal in the frequency domain and a comparison with a threshold. By adjusting the standard deviation of the added noise and the threshold factor it is possible to control the sonic features of the synthesized sound. This technique can be applied to both stationary and non-stationary sounds.
