Sparse Frequency-Domain Reverberator

Numerous applications require realistic and computationally efficient late reverberation. In this paper, the perceptually relevant properties of reverberation are identified, and a novel frequency transform domain reverberator that fulfills these properties is proposed. Listening test results confirm that the proposed reverberator has a perceptual quality equivalent to the ideal solution of decaying Gaussian noise in frequency bands.
