In this paper an improved version of the instantaneous frequency attractors (IFAs) algorithm is presented, by introducing several solutions which reduce the number of spurious components especially for low signal to noise ratios (SNRs) and increase the accuracy of the frequency estimator. We perform multilevel comparison tests with both previous versions of… (More)
Based on the widely spread concept of instantaneous frequency (IF), we resumed the IF attractors (IFAs) method used for tonal components extraction from any given signal and we emphasized its essential advantages over traditional approaches by incorporating it into a popular application: the calculus of auditory masking threshold (AMT). Using MPEG1 Layer 1… (More)
