Sound source localization system pinpoints vocal emission during unrestrained dyadic interactions between male and female mice.

Examples of signals assigned to either the female (A) or the male (B). Photograph of the arena (left) at the time of vocal emission indicates the positions of the mice (female = orange, male = blue) and the microphones (Mic 1–8 = □). Filled wedge indicates the mouse that emitted the vocal signal. The vocal signals, which were detected on the microphones surrounding the arena, are shown in the spectrograms to the right.
