Noise Modules by the numbers
Measured across all 9 models we track, not a sample.
Median $90 — half of all noise modules here cost less.
How to choose the best noise modules
Noise Types
Does it offer a variety of noise types - white, pink, brown, filtered, granular? A wider palette means more sonic possibilities, crucial for evolving textures.
Modulation Options
Can you modulate the noise's pitch, density, or filtering? Static noise gets boring fast; modulation breathes life into it.
Signal-to-Noise Ratio
This is critical. A noisy noise module is just...noise. A good one will have a decent S/N ratio so you can hear the subtleties.
Filtering Capabilities
A resonant low-pass filter can turn white noise into a screaming drone. A high-pass can add crispness. Versatility is key.
Build Quality
At this price point, expect some compromises. We're looking for something that won't fall apart if you bump it in your rack, even if the case isn't the fanciest.
Buying guide
Alright, so you're diving into the modular world and need some noise? Smart move - a little controlled chaos goes a long way. Finding good noise modules under $200 can be tricky, though; you're not gonna get the boutique, ultra-refined textures of the top-tier stuff. But there are some seriously usable options out there that'll add grit, texture, and unpredictable movement to your patches without breaking the bank. Let's get into it.
Real talk: under $200, you're making trade-offs. Don't expect ultra-low noise floors or exotic noise generation techniques. Often, you'll find simpler designs with fewer modulation options, but that's not always a bad thing.
Focus on modules that offer a good range of noise types and, crucially, decent filtering - that's where you'll get the most mileage. A cheap module with a good filter is worth more than a 'complex' module that just makes generic hiss.

Questions
What's the difference between white, pink, and brown noise?
White noise is that classic hiss, like static. Pink noise has more low-end, sounding 'fuller' or 'warmer'. Brown noise is even more bass-heavy, almost a rumbling texture. They all have different feels and applications.
Can I use these modules for percussion sounds?
Absolutely! With some clever gating and filtering, you can create surprisingly realistic drum sounds or glitchy percussion textures. Think of brown noise as a good starting point for a gritty kick drum.
What does 'modulation' mean in this context?
It means using other signals - LFOs, envelopes, sequencers - to change the noise's characteristics in real-time. It's what transforms static noise into something dynamic and interesting.
Are these modules suitable for recording?
They can be, but be mindful of the noise floor. A noisy module can muddy a clean recording. Experiment with filtering and gating to tame the noise and make it work for your track.
Is there a 'best' module at this price?
Nah, it's all about what you need. Some excel at raw noise generation, others at filtering and modulation. Research a few, watch some demos, and choose the one that best fits your patching style.
