    摘要: Coding (1) of an audio signal is provided including estimating (110) a position of a transient signal component in the audio signal, matching (111, 112) a shape function on the transient signal component in case the transient signal component is gradually declining after an initial increase, which shape function has a substantially exponential initial behavior and a substantially logarithmic declining behavior; and including (15) the position and shape parameters describing the shape function in an audio stream (AS).
