File Information
Description

Python version: https://github.com/nssh/dsp

This folder contains two simple functions (zerocross and energy) to compute STE and STZCR.

The script zcr_ste_so.m uses these two and other functions (included) to compute the STE and STZCR
of the word 'so'.

See the respective function help for more details.

thanks all.

@John, its not a simple multiply. Please get some reference on zero-cross rate.

A good work!! But, why you use convolution to multiplicate the window in the ZCR? It's not a simple multiply?
