The object of the invention is a method and a system for decomposition of acoustic signal into sound objects having the form of signals with slowly-varying amplitude and frequency, as well as sound objects and their use. The object is achieved by a method for decomposing an acoustic signal into digital sound objects, a digital sound object representing a component of the acoustic signal, the component having a waveform, comprising the steps of converting the analogue acoustic signal into a digital input signal (PIN); determining an instantaneous frequency component of the digital input signal,using a digital filter bank; determining an instantaneous amplitude of the instantaneous frequency component; determining an instantaneous phase of the digital input signal associated with the instantaneous frequency; creating at least one digital sound object, based on the determined instantaneous frequency, phase and amplitude; and storing the digital sound object in a sound object database.
