Transients are short intervals during which the signal evolves quickly in some nontrivial or relatively unpredictable way (Bello, 2005). In computer music, the short attack portion of a sound is often treated as a transient signal. — Click for http://en.wikipedia.org/wiki/Transient_%28acoustics%29

Noise (in signal processing) is a random signal. In the language of statistical signal processing, a noise signal is typically modeled as 'stochastic process', which is in turn defined as a sequence of random variables. — Click for https://ccrma.stanford.edu/~jos/sasp/What_Noise.html

Time scaling refers to modifying the time-duration of a signal without modifying its audio spectral characteristics. It is often used to slow down music without changing the pitch of any of the instruments. It is not possible to do this exactly in general, but good approximate methods exist using, e.g., the phase vocoder or Synchronous OverLap-Add (SOLA) algorithms. — Click for https://ccrma.stanford.edu/~jos/sasp/Time_Scale_Modification.html
