Abstract: An audio amplifier (20) which includes an arrangement (300) for influencing an audio signal applied to the audio amplifier (20). This arrangement (300) has an amplifier for additionally amplifying a high-frequency range of the audio signal relative to the rest of the audio signal. This additional amplification takes place once a value of the audio signal has exceeded a limit value. The additional amplification only takes place for a brief period of time. The audio amplifier additionally amplifies high-frequency peaks in the audio signal for a brief period of time. The rising and falling slopes of these peaks are briefly enlarged as a result. Especially for pop music, this appears to be an attractive effect.
