The Swezey Digital Filter Program

(Newly Updated Summer 2014)

Audio Restoration / Recovery / Noise Reduction

Restore old vinyl phonograph (LPs, 45 RPM, 78 RPM) or tape recordings.
or filter live audio in realtime for Shortwave Listening (SWL)

This program can accept either live real time audio input or prerecorded WAV audio files.
Listen to results in real time and/or save them to a WAV audio output file.

This program employs proprietary Digital Signal Processing (DSP) techniques for superior broadband filtering.


This program is not a general purpose "wave editor". It concentrates specifically on the recovery of difficult audio. While many wave editors will do some basic filtering it is not their primary focus.
I believe my program can significantly out perform them especially in the removal of in band "crackle" noise.
