AB  - This paper describes a processing approach which enables perceptually compelling modification of audio signals via accentuation or suppression of transients. The transient detection uses a frequency-domain analysis which yields a spectral. ux parameter. In typical detection methods, such a parameter would be compared with a threshold to derive a binary transient detection function. Here, we instead use an adjustable graded response to arrive at a continuous transient characterization function. This smooth function is used to drive a nonlinear frequency-domain signal modification. We demonstrate that binary detection is problematic for perceptual manipulation, that our approach overcomes these problems, and that our system is able to achieve substantial modification of a signal's perceptual attributes without introducing significant artifacts.
