The Swezey Digital Filter Program
Turn Your PC into a Digital Audio Filter
Newly Upgraded in Spring 2008
The program can accept input from either live real time audio or pre-recorded WAV audio files.
You can capture audio to WAV audio files for later use before or after filtering it.
Employs advanced Digital Signal Processing (DSP) techniques NOT just FIR or IIR band pass filtering.
Filter pre-recorded WAV audio files or live Line-In audio in real time to reduce crackle, pops and clicks, tape hiss and other types of noise.
Pops and clicks are among the most annoying problems in listening to vintage phonograph recordings. To correct for this I have developed an algorithm in the program that reduces them significantly. To learn more about this feature and hear a short example Click Here!
Auto equalization significantly enhances pre-1925 acoustical recordings. To learn more about this feature and hear a short example Click Here!
Fixed equalization is critical to get the most out of your 78 RPM phonograph records. This feature allows you to set the proper equalization curves for them. To learn more about this feature and hear a short example Click Here!
