The impulse response (IR) of a room, recorded by an omnidirectional microphone, is the starting point for basic room acoustics. The square of the IR is considered to represent the distribution of how energy arrives from the source to the microphone, and the most commonly used acoustic parameters are obtained from it, using specific IR software. The method for obtaining these parameters depends in part on the software used and the parameters calculated on acoustic frequency bands. In this work, we present a new tool for analyzing the impulse response (IR) of a room: the characteristic function, an approach for globally characterizing rooms directly using the IR signal measured. Using this method greater or lesser variability of IR, measured at different points of a room, can be shown. In general, a linear dependence of distance between characteristic functions at different points from the source is found.
