You can use Control system approach to filter this signal as follow
[data, fs] = audioread('sample.wav');
T = 1/fs;
t = (0:size(data,1)-1)'*T; % get time of samples;
filter = tf(18181818, [1 9090.9090909090 18181818.181818]);
channel1_filtered = lsim(filter, data(:,1), t);
channel2_filtered = lsim(filter, data(:,2), t);
