Transient Models

A more recent addition to sines+noise modeling is explicit transient modeling [7,132,130,127,131,266,261]. These methods address the principal remaining deficiency in sines+noise modeling, preserving crisp ``attacks'', ``clicks'', and the like, without having to use hundreds or thousands of sinusoids to accurately resynthesize the transient. (The noise component cannot be used, in general, because no matter how much resolution is provided in the amplitude envelope of the noise, there is usually no guarantee that the noise, being random, will have the desired amplitude at the critical time it is needed.)
