Spectral analysis: PSD, spectrograms, coherence, and multitaper methods.

Submodules

psd : Power spectral density estimation (Welch, periodogram). multitaper : Multitaper spectral estimation and F-tests. specx : Short-time spectrograms and time–frequency representations. bivariate : Coherence, phase-locking value, and cross-spectral measures. features : Band-power extraction, spectral edge, and peak frequency. whitening : Spectral flattening and 1/f removal. process_spectrogram : Post-processing utilities for spectrogram arrays.
