Modifying transients for efficient coding of audio
Renat Vafin, R. Heusden, Willem Bastiaan Kleijn · 2002
We propose a method for efficient representation of transients in audio signals. We estimate the transient component of an original audio signal and modify the locations of the transients in such a way that the transients can occur only at locations defined by a relatively coarse time grid. This procedure allows an efficient representation of transients with damped sinusoids. We also verify that the introduced modifications do not result in a perceptual difference between the original and the modified audio signals.
