<p>Audio compressor device (20) for processing an audio signal and controlling a signal amplifier (24), comprising a signal analyser function (27,29) devised to analyse an input signal during a time frame (28) to determine if the signal represents noise or audio data, wherein the audio compressor device is adapted to set a gain for the signal amplifier dependent on the analysis. The analyser function may comprise an auto-correlation function (27), operative to perform auto-correlation of the input signal in a process for determining if the signal represents noise or audio data.</p> |
