Run a vocal through that IR: the voice learns the can’s loneliness. Run a kick drum through a deconvolved cathedral: the beat prays.

After Voxengo Deconvolver - WiN

Deconvolver listens to both: the question (sweep) and the stained answer (recording). Then it divides them. Not division like arithmetic— division like finding the ghost between two mirrors.

You feed it a pure rising scream— 20 Hz to 20 kHz, slow as honey. The room answers. Not an echo, not a reverb tail. Something deeper: a fingerprint of air, of drywall, of the chair’s shadow.
