pyroomacoustics

Pyroomacoustics is a package for audio signal processing for indoor applications. It was developed as a fast prototyping platform for beamforming algorithms in indoor scenarios.

FRIDA

A high-resolution direction-of-arrival finding algorithm relying on finite rate of innovation sampling with a robust reconstruction algorithm.

DSPNumex

Numerical examples examples for the DSP class by Martin Vetterli and Paolo Prandoni on coursera.

SignalsOfTheDay

This is a collection of signals interesting for historical or cultural reasons. Each signal is described and analyzed in an [ipython notebook](http://ipython.org/notebook.html).
