ABSTRACT:
The invention concerns a circuit for adapting the signals from different channels (L, R) delivered by an audio reproduction system (10) in conditions specific to headset listening. It comprises: means (14a) for producing a left-channel intermediate signal resulting from the addition of at least a signal addressed to the left channel (L) to at least one signal addressed to the right channel (R) delayed by a first time interval, and a right channel intermediate signal (R1) resulting from the addition of the signal addressed to the right channel (R) to the signal addressed to the left channel (L) delayed by the same time interval, and means (14b) for producing an adapted left channel signal (Lc) resulting from the addition of the left channel intermediate signal (L1) to the right channel intermediate signal (R1) delayed by a second time interval and an adapted right channel signal (Rc) resulting from the addition of the right channel intermediate signal (R1) to the left channel intermediate signal (L1) delayed by the same time interval.
