How would I get effects that mimic the Subdecay Noise Box?

Sup guys.

I was watching this video today and I wanted to know how I could get the awesome effects from the Subdecay Noise Box guitar pedal without spending a dime on the pedal itself.

Is there an effect in Audacity that would sort of mimic this pedal?

I don’t think a Ring Mod would do the trick so if you guys could help me out, I’d be very grateful.

Thanks for reading my post!

Neither do I.
There are LOTS of free effects available for Audacity as plug-ins
though I don’t know of any single effects that emulate the Subdecay Noise Box. After all, that is the main selling point of the device - its unique sound.

You may be able to emulate a similar kind of effect by making a number of duplicates of your recorded guitar, then apply different amounts of distortion to each track, then use a modulator to apply AM modulation (amplitude modulation) using a duplicate of the original (clean) track as the modulation source and the distorted track as the carrier (this will provide a kind of envelope control).

In Audacity you can also create your own plug-in effects using Nyquist If you are interested in giving that a go I could probably give you some pointers to get you started.

Alternatively, you could look at chaining a number of different effects using, for example, in Linux Jack Rack, or in Windows you may be able to use Buzzmachines (

Alright. Which Ring Mod for AM setting should I use?

Have a look for “Ring Modulator with two inputs” by Steve Harris.
Set the slider to “1” for Amplitude Modulation.

That effect is alright I guess but it barely did anything like that pedal.

But I understand, that IS the selling point for the pedal so you’re right in that aspect. Is there anything else I can do to achieve it with maybe flange?

*I seriously have all the free effects so lemme know what to use :slight_smile:

If it was me wanting to emulate that effect, I would try to recreate it by writing my own plug-in with Nyquist, but there would be a lot of work involved and I don’t personally have the time or motivation to attempt such a job. Anyhow, playing around with multiple effects can produce some really groovy effects, and by just experimenting with multiple effects you might well find sounds that you like better than that effects box. I would suggest that you just experiment with every effect that you have, see (hear) what each of them does individually, and then see what they can do when you combine them.

Combining effects can be done in several ways -
you can mix them from separate tracks,
you can apply one, then apply another to the result (note that with some effect combinations you will get a different sound if you apply effect A followed by effect B, than if you apply effect B followed by effect A).
you can modulate one processed track with another processed track (either AM or ring modulation).
you can use one audio track as the “noise profile” in the noise reduction effect, and apply it to another track.
you can use the vocoder effect to “vocode” one sound agaist another.

The possibilities are endless, just use your imagination, experiment, and have fun with it.
