Hi,now i design filter bank with 16 bands.I use a music(15s) through it, but when i hear the filter result ,it sounds so rough.Later,i find i can use analysis filter with integrated filter,but i do not know how to design.thank you!
there are my code
% ues fdesign.bandpass to design bandpass filter bank
% y filter result;
% x signal;
% fp1 left passband fre;fp2 right passband fre; fstop1 left stopband fre;fstop2 right fre;rp,rs

Based on my understanding you want to reconstruct the original signal by using analysis filter. The link attached below might be helpful for you, as it contains an example for " how to design perfect reconstruction using two-channel filter banks":
Hope it helps.
