A recursive implementation of reverberation is given by (2.103) which is given below y[n] = x[n] + ay[n − D], where D = τFs is the delay in sampling interval given the delay τ in seconds and sampling rate Fs and a is an attenuation factor. To generate digital reverberation we will use the sound file handel which is recorded at Fs = 8192 samples per second. (See Problem 6 for using this file.)
(a) For τ = 50 ms and a = 0.7, obtain a difference equation for the digital reverberation and process the sound in handel. Comment on its audio quality
Hello i have this question and i am stuck in a part where i can't form the equation i am looking for someone to help me out
load handel.mat
Fs=8192;
tao=milliseconds(50);
alpha=0.7;
filename = 'handel.wav';
audiowrite(filename,y,Fs);
d=tao*Fs;
x=transpose(y)
---then??
sound(y,Fs)
