A Python signal processing package for computing spectral- and time-domain interactions using the bispectrum.

This package provides the tools for computing phase-amplitude coupling, time delay estimation, and waveshape features using the bispectrum and bicoherence. Additional tools for computing amplitude-amplitude coupling, phase-phase coupling, and spatio-spectral filters are also provided.

Parallel processing and Numba optimisation are implemented to reduce computation times. There is a minor reliance on the MNE signal processing toolbox.
