An M-File for automated tremor analysis which returns the amplitude and frequency of tremor recorded with Polhemus Fastrak.Relies on functions within the Signal Processing and HOSAtoolboxes.

It can be used in image recovery actions, image processing tasks, in signal processing, in simulations or optimization tasks.

Audio Compressor & Limiter is a cross-platform Java application which works on Linux, Windows and Mac OS X. The program takes audio data from a selected input sound device/mixer applies compression as well as brick wall limiting and sends the processed data to the chosen output sound...
