Techniques for regenerating reverberation include generating a reverberation signal based on a source signal and a response of a listening space, generating a compressed reverberation signal by increasing output levels of a first portion of the reverberation signal having output levels below a threshold level more than output levels of a second portion of the reverberation signal having output levels above the threshold level, and combining the compressed reverberation signal with the source signal to form an output signal for the listening space.
