A new optimisation criterion for computing excitation sequences, typically used in analysis by synthesis linear prediction coders, is presented. This criterion not only relies on the error over the processed frame but also includes the excitation effects induced in future frames. This technique is effective in removing ticks that are otherwise audible.
