Abstract: The sound power produced by an acoustic source comprises its total sound energy radiated in all directions per unit time. As the global emission, it excites the reverberant field of a surrounding room. Conversely, an acoustic signal detected for audio applications, including driving reverberation effects, often results from a microphone at a discrete location that does not capture the global source sound and its sound-power spectrum. This paper explores several physical bases for how measured high-resolution spherical directivity functions and known room conditions allow audio engineers to optimize a microphone position to yield a signal with a mean-squared spectrum best approximating the time-averaged sound-power spectrum. The proposed approaches provide means to capture the global source sound with its attendant audio benefits, including the production of more realistic reverberation effects.
