off the walls, ceiling, and floor on the way to your ears. All these

reflected sounds reach your ears so closely together that you don’t perceive

them as separate echoes, but as a sonic ambience that creates an impression

of space. </p>

<p>In Soundbooth, you can use the Convolution Reverb

effect to reproduce rooms ranging from coat closets to concert halls.

Convolution-based reverbs use <dfn class="term">impulse</dfn> files to simulate

acoustic spaces. The results are incredibly realistic and life-like. </p>

Convolution Reverb requires significant processing, you may hear clicks
