NoLias: Anti-Alisaing tool for Windows and Mac

We created NoLias as a quick way to determine if there’s a risk of aliasing distortion created in a plugin chain. It doesn’t use any high-tech rocket science to analyze the signal. All it does is send out a customized sine wave to let your ears do the heavy lifting. Sometimes, the no-frills solution does the job better than any other approach.

When NoLias play its customized sine sweep, you’ll immediately hear if the sine signal folds down above the Nyquist frequency and start to “mirror” itself back into the audible spectrum (see the video for an example).

The plugin consists of an on/off switch, level control for the sine sweep, and a simple spectrum analyzer. The analyzer doesn’t have a function, it’s just there because it looks cute. In “off” mode, NoLias passes the signal from the input to the output untouched. When turned on, it starts to play the sweep.

How to use:

  1. Put it as the first plugin in your effect chain.
  2. Turn on the sweep.
  3. If you hear a clean sine sweep you can stop here. If you hear aliasing as the sweep gets closer to 20kHz, continue to step 4.
  4. Start bypassing plugins. If it goes away when you bypass a plugin, you’ve found the culprit.

There are a few ways to get rid of aliasing.

  1. Check if the plugin has built-in oversampling and turn that on.
  2. Upsample the project (start by doubling the sample rate).
  3. Skip the plugin or use a similar plugin
