ECE 408 COMPUTER ASSIGNMENT #7 SOUND EFFECTS Useful blocks: Signal Processing Blockset Platform Specific I/O Windows (WIN32) From Wave Device From Wave File To Wave Device To Wave File Signal Processing Blockset Signal Management Buffers Delay Line 1. (Delay) Connect a microphone to Simulink and pass it through a delay specified by y(n) = x(n D). Send the output of the delay to speakers. Adjust D so that you can clearly hear the delay. (a) Plot the waveforms in the time domain before and after the delay. (b) Plot the spectrums (fft magnitude) before and after the delay. (c) Plot the impulse response, magnitude response, phase response, pole-zero diagram of the system. 2. (Echo) Connect a microphone to Simulink and pass it through a delay specified by y(n) = x(n) + a x(n D). Send the output of the delay to speakers. Adjust a and D so that you can clearly hear the

(Reverberation) Connect a microphone to Simulink and pass it through a system specified by y(n) = x(n) + a 1 x(n − D) + a 2 x(n − 2D) + a 3 x(n − 3D) Send the output of the system to speakers. Adjust a 1 , a 2 , a 3 and D so that you can clearly hear the reverb. 1 (a) Plot the waveforms in the time domain before and after the reverb.
