Abstract
An important problem in physics concerns the analysis of audio time series\ngenerated by transduced acoustic phenomena. Here, we develop a new method to\nquantify the scaling properties of the local variance of nonstationary time\nseries. We apply this technique to analyze audio signals obtained from selected\ngenres of music. We find quantitative differences in the correlation properties\nof high art music, popular music, and dance music. We discuss the relevance of\nthese objective findings in relation to the subjective experience of music.\n

This work analyzes two classes of controls consisting of patchy nucleotide sequences generated by different algorithms--one without and one with long-range power-law correlations, finding that both types of sequences are quantitatively distinguishable by an alternative fluctuation analysis method.

A new method--detrended fluctuation analysis (DFA)--for quantifying this correlation property in non-stationary physiological time series is described and application of this technique shows evidence for a crossover phenomenon associated with a change in short and long-range scaling exponents.

1,380 Citations2001Jan W. Kantelhardt, Eva Koscielny–Bunde +3 more
It is shown that deviations from scaling which appear at small time scales become stronger in higher orders of detrended fluctuation analysis, and a modified DFA method is suggested to remove them.

It is shown how to use DFA appropriately to minimize the effects of trends, how to recognize if a crossover indicates indeed a transition from one type to a different type of underlying correlation, or if the crossover is due to a trend without any transition in the dynamical properties of the noise.

It is found that introducing nonstationarities to stationary correlated signals leads to the appearance of crossovers in the scaling behavior and it is shown how to develop strategies for preprocessing "raw" data prior to analysis, which will minimize the effects of non stationarities on the scaling properties of the data.

An open question in computational molecular biology is whether long-range correlations are present in both coding and noncoding DNA or only in the latter, and the near-perfect agreement between the two independent analysis methods, FFT and DFA, increases the confidence in the reliability of the conclusion.

The degree to which concepts developed in statistical physics can be usefully applied to physiological signals is explored, and very recent work that quantifies multifractal features in these cascades is described, and the discovery that the multifractional structure of healthy dynamics is lost with congestive heart failure is described.

This work test the hypothesis that the scaling properties of the dynamics of healthy physiological systems are more stable than those of pathological systems by studying beat-to-beat fluctuations in the human heart rate, and develops techniques based on the Fano factor and Allan factor functions for quantifying deviations from uniform power-law scaling in nonstationary time series.

The alpha coefficient of DFA can be described in power-spectral terms, which facilitates exploration of its physiological basis, and it is shown F2 can be obtained from a frequency-weighted power spectrum without DFA.

A link between certain problems that arise when digital audio signals are processed, and a branch of mathematical theory, called Gabor analysis, is established, and the idea of locally adaptive sets of building blocks will yield a generalisation of spectral domain methods especially helpful in the investigation of music signals.
