DEVICE FOR AND METHOD OF ADDING REVERBERATION TO AN INPUT SIGNAL

摘要

A device (1) for adding reverberation to an input signal (s(n)) uses a corresponding transformed input signal (S(n)), for example the Fourier transform of the signal, to generate reverberation. The device comprises circuits (3, 5, 6) for combining the transformed input signal (S(n)) with a modified and delayed transformed output signal (G(Sr(n-i))) so as to produce a current transformed output signal (Sr(n)). Inversely transforming the current transformed output signal (Sr(n)) results in an output signal (sr(n)) having reverberation.
