Collection of Python utilities for signal analysis

Project Description

*thLib* contains functions for working with sound, and for fitting circles,
lines, sine-waves, and exponential decays. For signal processing, a
Savitzky-Golay filter is included, as well as a demonstration of the
calculation of a power spectrum. UI utilities, and a few useful vector
functions (e.g. an implementation of the Savitzky-Golay algorithm) round off

**Note:** All functions for working with 3D kinematics have been moved into
the new package "scikit-kinematics"!

Compatible with Python 2 and 3.

numpy, scipy, matplotlib, pandas, statsmodels, skimage, sympy
