The perfect plugin for when your other plugins sound too perfect
LO-FI-AF brings you on a journey through your favorite audio artifacts of the past few decades. Using impulse responses, spectral shaping, and other techniques, it conjures up the idiosyncrasies of everything from vinyl records and analog radios to MP3s, CDs, cassettes, cell phones and beyond.

Dirt, distortion and degradation from analog to digital
This versatile plugin does much more than other saturators and bit crushers. In addition to the tape saturation, vintage mics, and vinyl dust and pops, it recreates the sound of CD skipping, MP3 chirps, radio interference, and even the chatter made by a cell phone placed too close to a speaker.

Make custom signal chains with 4 unique modules
Each of LO-FI-AF's sections can be toggled and reorganized for a total of 24 different signal paths. Do you want to add some analog grunge before the MP3ification? Sure! Want to make it sound like it was recorded through a busted microphone, burned to a CD, and then scratched up? Why not?! Use it to add vibe and nostalgia to your tracks, or completely demolish source material into something practically unrecognizable.

Intuitive and easy to use
LO-FI-AF features a stunning new graphical interface by Papernoise, the designer behind some of the most beautiful music software and hardware around. Its intuitive layout makes all the features visible and available at once without overwhelming the eye. There are 14 skins included, allowing you to find the perfect color combination for your setup and style.

  • A Convolution section includes impulse responses from broken microphones antiquated speakers and other special devices.
  • The Spectral section creates pitch shifting, audio rippling, and MP3 artifact effects.
  • The Digital section provides bit crushing, sample rate degradation and CD skipping effects.

  • Beautiful and simple to navigate GUI puts all the controls at your fingertips in an easily manageable way.
  • A versatile collection of artifacts and processing not found in other plugins, sure to spice up your productions in new ways.
