Some signal-analysis-related Python scripts: Several different methods of estimating the frequency of a waveform Peak detection for spectra Measure total harmonic distortion plus noise of a sine wave (THD+N) Apply an A-weighting filter to audio files I’m sort of intending to combine them all into one eventually.

A simple FastICA example

Wikipedia describes independent component analysis as “a computational method for separating a multivariate signal into additive subcomponents supposing the mutual statistical independence of the non-Gaussian source signals”. (Clearly, this was written as part of their campaign to make technical articles accessible.) In normal people words, ICA is a form of blind source separation — a […]
