Spectrum is a Python library that contains tools to estimate Power Spectral Densities based on Fourier transform, Parametric methods or eigenvalues analysis:

  • The Fourier methods are based upon correlogram, periodogram and Welch estimates. Standard tapering windows (Hann, Hamming, Blackman) and more exotic ones are available (DPSS, Taylor, …).
  • The parametric methods are based on Yule-Walker, BURG, MA and ARMA, covariance and modified covariance methods.
  • Non-parametric methods based on eigen analysis (e.g., MUSIC) and minimum variance analysis are also implemented.
  • Finally, Multitapering combines several orthogonal tapering windows.

The targetted audience is diverse. Although the use of power spectrum of a signal is fundamental in electrical engineering (e.g. radio communications, radar), it has a wide range of applications from cosmology (e.g., detection of gravitational waves in 2016), to music (pattern detection) or biology (mass spectroscopy).
