A method of modeling (fig. 4, fig. 5) a characteristic of a non-linear system (21), comprises feeding test input signals (Sig6, Sig7) into the non-linear system (21) to obtain test output signals (Resp6, Resp7), wherein the test input signals (Sig6, Sig7) include a first test input signal (Sig6) and the test output signals (Resp6, Resp7) include a first test output signal (Resp6), identifying occurrences when an output level in at least one specific frequency band of the first testing output signal significantly changes under the first test input signal (e.g. identifying the frequencies at which there are overtones) so as to obtain a first profile (Profile B: frequency index versus input level, fig. 7), and modeling the characteristic (e.g. frequency response of pre-amplifier stage, fig. 8) based on the first profile (fig. 20). Various test input signals may be used : Amplitude sweep (fig. 6a-c), frequency sweep (fig. 10), white noise or chirp signal. The breakup point of overtones onsets in the table of frequency bins versus input signal is determined. The application of this profile to model the non-linear amplifier stage of a music instrument, for instance a guitar, is also defined.

A device for synthesizing sound having sinusoidal components includes a selector for selecting a limited number of the sinusoidal components from each of a number of frequency bands using a perceptual relevance value. The device further includes a synthesizer for synthesizing the selected sinusoidal components only. The frequency bands may be ERB based. The perceptual relevance value may involve the amplitude of the respective sinusoidal component, and/or the envelope of the respective channel.
摘要:
A method for analyzing sound is described. In accordance with one example of the invention the method includes: providing an input sound signal to be analysed and determining a fundamental frequency of the input signal from the input signal or from at least one guide signal. Furthermore, the frequencies of higher harmonics of the fundamental frequency are determined, thus determining harmonic model parameters. A harmonic signal based on the harmonic model parameters is synthesized and a residual signal is estimated by subtracting the harmonic signal from the input signal. Residual model parameters are estimated based on the residual signal. Furthermore, a corresponding method for synthesizing a sound signal is described.
