AB  - In this paper we describe a signal processing technique for enhancing audio signals based on manipulation of their modulation spectra. The modification is achieved by. Filtering the time trajectories of spectral envelopes in different frequency bands. Scaling of higher modulation frequencies with shelving. Filters is used to modify rapidly changing acoustic events, thus effectively enhancing transient components without the need for explicit detection. The perceptual effect of such modifications is analogous to the edge processing applied to images, where acoustic details can either be smoothed or sharpened depending on the desired quality of the sound.
