Speaker arrays can synthesize convincing reverberation where none exists naturally.

Evidence

Electronic enhancement of sound to “improve” a concert hall reached a zenith with Chicago’s outdoor Pritzker Pavilion soundspace (see figure 27.13), which started with no hall at all! No significant natural reverberations are present save those bouncing off the ground and the back stage. Carefully programming of dozens of loudspeakers placed overhead on thin arches makes the space sound like an enclosed concert hall. — Eric J. Heller, Why You Hear What You Hear- An…, 2538
