ENCODING OF TRANSIENT AUDIO SIGNAL COMPONENTS

摘要

A method of encoding ( 1 ) an audio signal (x(t) is disclosed. The position of a transient signal component of the audio signal is estimated ( 110 ). A first portion (ti) of the transient signal component is modeled ( 111 ) with a first plurality of sinusoidal components. A difference (d) between the first portion (ti) of the transient signal component and the transient signal component is estimated. The difference is modeled with a measure (E) of the energy of the difference; and the measure (E) is included in an audio stream (AS).
