A pitch adaptive circuit ( 200 ) includes an equalizer control circuit ( 206 ) that evaluates the pitch of the speech signals that are being processed and depending on the pitch information, the equalizer control circuit ( 206 ) selects an equalizer ( 208, 210 ) to shape the decoded speech signals. By selecting the best equalizer ( 208 or 210 ) to use based on the pitch information, improvements in audio quality are provided automatically without user intervention.
