AUDIO SIGNAL PROCESSING APPARATUS

摘要

The invention relates to an audio signal processing apparatus (400) for processing an audio signal, the audio signal processing apparatus (400) comprising: a converter (401) configured to convert a stereo audio signal into a binaural audio signal; and a determiner (403) configured to determine upon the basis of an indicator signal (405) whether the audio signal is a stereo audio signal or a binaural audio signal, the indicator signal (405) indicating whether the audio signal is a stereo audio signal or a binaural audio signal, the determiner (403) being further configured to provide the audio signal to the converter (401) if the audio signal is a stereo audio signal.
