1. A method for detecting and localizing a sound event in a sound in multiple audio channels in order to determine in which of the multiple audio channels to produce the sound event, the multiple audio channels comprising at least one channel pair, the channel pair comprising a first audio channel and a second audio channel, the method comprising:

  • detecting the sound event;

    comparing power, using at least one hardware processor, in the first audio channel with power in the second audio channel to produce a power differential steering angle of the power of the sound in the channel pair;

    when the sound event is detected, selecting, using the at least one hardware processor, which of the multiple audio channels to produce the sound event based on the power differential steering angle; and

    producing the sound event in the multiple audio channels based on selecting which of the multiple audio channels to produce the sound event.
