? Intelligent Signal Processing Test Angelo Ciaramella
Question 15 Effects are correlated with the modifications of an acoustic signal Question Reverbaration is based on convolution of the impulse response product of the impulse response convolution of the room noise ISP Verification tests
Effects General model for effects ISP Verification tests + [ ] D n g g z bl 1 ff = ( ) H z + K g z fb
Vibrato From the general model eliminating feedback and blending Delay less than 5 ms Size of delay line ISP Verification tests f = c D m 1 2 f 0
Flanging From the general model eliminating feedback and blending Delay in the range 1 ms 10 ms Equations ISP Verification tests = + [ ] [ ] [ [ ]] y n x n g x n D n ff = + [ ] sin( 2 ) D n D D f n 0 1 FL
Chorus At least two voices ISP Verification tests
Effects ISP Verification tests
Reverberation ISP Verification tests
Reverberation A simple approach is based on the convolution of the room impulse response A more sophisticated methodology is based on a perspective approach ISP Verification tests
