The frequencies that emerge as a result of ring modulation are ensured to never be harmonically related. This makes ring modulation useful in sound design as it can be used to emulate sounds of percussions with inharmonic frequencies like bells, chimes, etc.
What Is Ring Modulation?
Ring modulation is a type of amplitude modulation in which the modulation and carrier signals’ input levels are aligned to result in the emergence of new sum and difference frequencies. In contrast, the original carrier and modulation frequencies disappear totally.
Despite sounding simple, ring modulation can be very challenging to control. On the bright side, it can produce sounds doubtful to be achieved by any other synthesis method.
What Does Ring Modulator Do?
In short, a ring modulator multiplies 2 signals together, resulting in creating two frequencies: the sum and difference of the input frequencies.
How Does A Ring Modulator Work?
A ring modulator is a VCA with a special input. In VCA, when there is no CV, the output should be completely silent. Hence, carrier signals are blocked from passing when the modulation signal is zero, or less and negative signals are ignored altogether.
A ring modulator does the same, but instead of ignoring negative signals, it lets them pass but inverts them, making everything negative.
The 6 Best Ring Modulator VST Plugins In 2022
Listed below are 6 of the best Ring Modulator plugins used by popular sound designers and music producers.
1. Melda MRingModulatorMB
This plugin by MeldaProductions is one of the most advanced takes on ring modulation and offers you a ton of control options.
One of the most desirable things about this plugin is its 6 band control option with 2 oscillators. You may think to yourself, “one oscillator is confusing enough; why need 2?”. However, Melda’s implementation of those 2 oscillators over 6 bands makes its usage easier and more pleasing. In addition to that, Melda provides you with parameters that you can modulate independently. Each modulator can function as an LFO, envelope, audio level follower, randomizer, and pitch detector.
Since this is a MeldaProductions product, you get the usual M/S 8 channel surround sound, up to 16x up-sampling, A-H presets to aid your workflow, a built-in help system, and many more.
- The MRingModulatorMB offers one of the most innovative and advanced user interfaces in the market. It is resizable, stylable, and GPU accelerated
- It consists of 2 user interfaces, a simple one for beginners and an advanced interface for professional users who would like to have in-depth control
- A visualization engine that is distinctive in its own way with classic meters and time graphs
- You can control the effect independently over 6 different bands
- Adjustable oscillator shape technology
- M/S, single-channel, up to 8 channels surround processing
- Smart randomization to generate random settings to help serve as a starting point
- This plugin implements the Automatic Gain Compensation (AGC) technique to help regulate the overall volume level of your audio
- The ring modulation effect in this plugin can be tempo-synced to match the host BPM
This plugin is compatible with Windows 7 or higher for PC and macOS 10.9 or higher for Mac. It comes in VST/VST3/AU/AAX versions and supports 32 or 64-bits for PC but 64-bits only for Mac.
Overall, this ring modulation plugin is a unique addition to the several high-quality plugins by MeldaProductions. Its advanced GUI and dual interface modes help you have a more organized and more efficient workflow. Moreover, the in-depth control that you get over the effect is totally unmatched.
2. KiloHearts Ring Mod
This simplistic plugin by KiloHearts emulates analog ring modulation to provide you with a classic sounding tool.
Secondary signals inherited by this plugin include input signal and its sidechain, a sine wave oscillator, and a low and bandpass filtered noise. All those parameters can be shaped using the Bias and Rectify controls. Then you have the Frequency control knob, which is responsible for setting the filter or the oscillator’s cutoff frequency. Next to it, the Spread control knob manages the stereo width of the effect. Finally, the Mix knob controls the Wet/Dry levels, which enable parallel processing.
- A simple interface that allows for easy usage and maximum efficiency
- A modulator that provides you with control over a sine wave oscillator as well as a low and bandpass filtered noise
- The interface of this plugin is resizable to enable it to fit multiple displays and DAWs
- Control parameters are fully automatable
- Settings panel which contains multiple presets to help you get a starting point
KiloHearts Ring Mod is compatible with Windows 7 or higher for PC and OS X 10.10 or higher for Mac. It comes in VST/VST3/AU/AAX formats and supports 64-bit systems only.
KiloHearts provides you with everything you need to generate ring modulation. Its simple design and straightforward control knobs enable faster workflows and higher efficiency. However, its simplicity is also its downside since it is compromised in terms of versatility and controllability, limiting the range of sounds that it can generate.
3. Stagecraft RingMod
Stagecraft RingMod is a lightweight, easy-to-use ring modulation plugin that offers you a surprisingly decent amount of control.
This plugin has a very organized interface. The main focus point is the XY pad present in the center of the interface that allows you to control the modulation. To the right, you have the controls for the flanger, chorus, and LFO filters. You can choose to enable or disable any effect that you need. In addition to that, there is the Warp tool, which helps time sync the oscillators to match your host tempo or to different timing like a quarter note, triplet, etc.
Unlike most plugins, RingMod allows you to generate the ringing effect by choosing 5 different waveforms instead of the traditional sine wave only. Additionally, RingMod offers pulse width modulation, which expands the range of possibilities for this effect.
- RingMod is one of few plugins that allow you to use a waveform other than sine wave to generate the ringing effect
- Various syncing settings include straight, 1/4 note pulse, offbeat triplet, or 64th notes. In addition to that, flangers, choruses, and Filter LFOs can also be tempo-synced
- All parameters in this plugin are fully automatable
- You have a choice between a handful of presets to make your lives easier. Additionally, you can create your own presets for later use
This plugin requires Windows 7 or higher for PC and OS X 10.7 or higher for Mac. It comes in VST/VST3/AU/AAX formats and supports 64-bit systems only.
In conclusion, if you are looking for a simple ring modulation plugin with all the basic control parameters, you won’t be disappointed by Stagecraft’s plugin, as it offers all of that and more. It also has features that separate it from the rest of the market, like enabling ring modulation using 5 different waveforms instead of 1.

6. de la mancha Ring Thing (FREE)
Ring Thing is another impressive Ring Modulator plugin that is developed by de la mancha. It packs impressive features on a simple interface.
The interface in this plugin revolves around a big XY pad the is placed in the center. This XY pad controls the frequency and mix level of the ring modulator. Each axis on the XY pad is modulated independently using a tempo-sync LFO, and the modulation is displayed graphically on the XY pad. Below the XY pad, you have controls for the ring modulation waveform where you can choose between several waveforms.
- This plugin provides you with 9 types of ring modulation, each with different tonal qualities
- 11 different ring modulation waveforms that allow you to have in-depth control over the effect
- XY pad to control the frequency modulation
- Wet/Dry level mix for parallel processing
- Each axis can be tempo-synced using its own tempo-sync LFO that allows for in-depth control
- 7 LFO waveforms as well as a “random” waveform
- LFO’s can be damped and inverted
- This plugin has a graphical display of the modulation on the XY pad
- You can add more complexity to the modulation since LFO can be synchronized
Like the Ring Modulator 101, Ring Thing is a Windows plugin that requires Windows 7 or higher. It comes in VST format and supports 32 and 64-bit systems.
Overall, Ring Thing is a pretty awesome ring modulator, given the fact that it is a free plugin. Its inclusion of an XY pad to control the modulation effect makes it so much more controllable when compared to the counterparts that do not possess it. However, it is a pretty outdated plugin that needs some refurbishment and better support for more devices.
