问一下陷波法 #1
Description
for i = 1:length(x)
xs1 = [x(i)+temp; xs1(1:end-1)];
y2(i) = K*(xs1'*c);
y2(i) = min(1,y2(i));
y2(i) = max(-1,y2(i));
d = y2(i); % iir滤波输入
for k = 1:size(iir_coef,1) % iir滤波过程
iir_buffer(k,1:3) = [d, iir_buffer(k,1:2)];
d = iir_buffer(k,1:3) * iir_coef(k,1:3)' - iir_buffer(k,4:5) * iir_coef(k,5:6)';
iir_buffer(k,4:5) = [d, iir_buffer(k,4)];
end
y2(i) = d;
xs2 = [y2(i); xs2(1:end-1)];
temp = xs2'*g;
end
你这一段为啥是再中间加滤波呢，这不是原始声音么
