In-car communication (ICC) systems supporting speech communication in noise by reproducing amplified speech from the car cabin in the car cabin ask for low-delay acoustic echo cancellation (AEC). In this paper we propose a delay-flexible DFT-based stereo AEC capable of cancelling also the echoes stemming from the audio player or FM radio. For the price of a somewhat higher complexity we are able to reduce the 32 ms delay of the baseline down to 4 ms, loosing only 1 dB in ERLE while even preserving system distance properties.
