This website is designed to explore techniques for extracting EVP (Electronic Voice Phenomena) signals from noise using EVPamp.

EVP Amplification Software - Background

 The original 2005 version software was the result of a series of experiments to see what happens if sophisticated signal processing techniques are used to extract speech from noise. Originally called EVP amplifiers because they amplify the vocal portions of a noise signal, though the operation is technically that of a filter.
