<p>The invention relates to a compressor and method for amplifying an input signal with a controlled gain comprising the steps of: providing an output signal representing the input signal amplified by an initial gain; determining a signal level of the input signal or of the output signal; comparing the signal level with a threshold level; if the signal level is below the threshold level, updating the initial gain value using an adaptive control characteristic; and if the signal level is above the threshold level, updating, dependent on the signal level, the initial gain value using a fixed control characteristic or an adaptive control characteristic respectively; the adaptive control characteristic being dependent on the signal level and the fixed control characteristic being independent from the signal level.</p> |
