Data structure that stores the beats register and information related to it
Reference to the data structure that will contain the variability analysis
Size of window for calculations (seconds)
Displacement of window for calculations (seconds)
Points for calculation (zero padding). If the user does not specify it, the function estimates a propper value.

Type of analysis used to calculate the spectrogram. Possible options are "fourier" or "wavelet"
Mother wavelet used to calculate the spectrogram when a wavelet-based analysis is performed. The available wavelets are: "haar" wavelet; least asymmetric Daubechies wavelets of width 8 ("la8"), 16 ("la16") and 20 ("la20") samples; extremal phase Daubechies of width 4 ("d4"), 6 ("d6"), 8 ("d8") and 16 ("d16") samples; best localized wavelets of width 14 ("bl14") and 20 (" bl20") samples; Fejer-Korovkin wavelets of width 4 ("fk4"), 6 ("fk6"), 8 ("fk8"), 14("fk14") and 22 ("fk22") samples; minimum bandwidth wavelets of width 4 ("mb4"), 8 ("mb8"), 16 ("mb16") and 24 ("mb24"); and the biorthogonal wavelet "bs3.1"
Maximum error allowed when a wavelet-based analysis is performed. It can be specified as a absolute or a relative error depending on the "relative" parameter value
Logic value specifying which kind of bandtolerance shall be used (relative or absolute). The relative tolerance takes into account the width of each of the intervals of interest.
