摘要： 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.

摘要： 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 system for decomposition of acoustic signal into sound objects having the form of sinusoidal waveforms with slowly varying amplitude and frequency, comprising a sub-system for determining parameters of a short term signal model and a sub-system for determining parameters of a long term signal model based on said parameters, wherein said subsystem for determining short term parameters comprises a converter system for conversion of the analogue acoustic signal into a digital input signal P IN characterized in that said subsystem for determining short term parameters further comprises a filter bank (20) with filter central frequencies distributed according to logarithmic distribution, each digital filter having a window length proportionally to the central frequency wherein each filter (20) is adapted to determine a real value FC (n) and an imaginary value FS (n) of said filtered signal, said filter bank (2) being connected to a system for tracking objects (3), wherein said system for tracking objects (3) comprises a spectrum analysing system (31) adapted to detect all constituent elements of the input signal P IN , a voting system (32) adapted to determine the frequency of all detected constituent elements based on maximum values of the function FG(n) resulting from a mathematical operation reflecting the number of neighbouring filters (20) which output an angular frequency value substantially similar to an angular frequency value of each consecutive filter (20), and in that said subsystem for determining long term parameters comprises a system for associating objects (33), a shape forming system (37) adapted to determine characteristic points describing slowly-varying sinusoidal waveforms, an active objects database (34) and a sound objects database (35).
