Abstract:
A method for influencing, in a radio receiver, a stereo channel separation of an audio signal to be reproduced, the audio signal being obtained from a received radio signal, the method comprising the steps of:(a) combining a sum signal and a difference signal, the combining yielding a signal for a left channel and a signal for a right channel of the audio signal in a stereo decoder; (b) delivering a factor to the stereo decoder, the factor influencing the stereo channel separation between the signal for the left channel and the signal for the right channel; (c) generating a first auxiliary field strength signal from a received field strength of the received radio signal, the first auxiliary field strength being indicative of the received field strength of the received radio signal; (d) generating a first auxiliary interference signal from at least one signal for indicating reception interference events, the first auxiliary interference signal being indicative of the reception interference events, the at least one signal being derived from the received radio signal; and (e) yielding the factor by combining the first auxiliary field strength signal, the first auxiliary interference signal and an auxiliary channel separation signal, the auxiliary channel separation signal being generated from a second auxiliary interference signal, the second auxiliary interference signal being derived from the first auxiliary interference signal, the second auxiliary interference signal being indicative of a number of the reception interference events per time interval.
