Swezey Java Digital Filter Program - (Updated Summer 2015)

"Making the WORLD Sound Better - One PC at a Time" - (Since 1999)

Audio Restoration / Recovery / Noise Reduction Software

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 real time live audio input or prerecorded WAV or AIFF 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 noise reduction. 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.
