Top 5 Comb Filter & Resonator Plugins 2021 | Melda, Kilohearts, Tritik

Top 5 Comb Filter & Resonator Plugins | Integraudio.com

Today we’ll talk about what a Comb Filter is and what it sounds like. Additionally, we’ll explore what a Resonator does in music and take a look at the best comb filter and resonator plugins for 2021!

But first, a little background information so everyone’s in phase… I mean, on the same page. Take a look!

What Is Comb Filtering?

Comb filtering is when two identical sound waves are slightly delayed due to sound reflections, multiple microphones, speaker positioning, or manually during post-production. This results in some of the wave’s frequencies adding together and some canceling out, resulting in a comb-shaped wave.

Depending on the frequency and rate of delay, sound can completely cancel itself or enhance the comb filter effect. If the delay is longer than 25ms, the effect gets significantly reduced, resulting in echo. As it’s impracticable to record a single frequency in the real world, sound recordings usually carry thousands of frequencies. Therefore, if two or more microphones capture the same sound source, chances are some frequencies will suffer from comb-filtering.

What Does Comb Filtering Sound Like?

Comb-filtering sounds very similar to a flanger effect, in which you hear frequencies sweeping through the source sound. Depending on the frequencies being affected, it sounds different. Usually, you can expect a hollowed, robotic sound due to the cancelation of some frequencies.

What Does A Resonator Do In Music?

Resonators pick one or multiple frequencies and vibrate in accordance with their amplitude, generating sound. Depending on the input signal’s intensity, resonators also change the frequency overtones’ strength, modulating its tonality. They’re used as effects in music post-production.

The 5 Best Comb Filter & Resonator Plugins 2021

1. UVI Shade

More Info & Price (Trial Available)

From the makers of Falcon 2, one of the best sound designing instruments ever created, comes this versatile equalizer capable of comb filtering and so much more.

While we will be focusing on the comb filter side of this plugin, we must still mention its grandeur when it comes to EQing. Shade is a digital equalizer with unlimited bands, numerous kinds of filters, modulation, side-chain, etc. It also employs a spectrum analyzer on its background to provide visual feedback.

Shade generates the comb filtering effect using a predefined comb shape rather than feedback or feed-forward delay. It’s more accurate and offers you a lot more control than you’d normally receive. You can also utilize the comb shape to amplify the comb frequencies instead of the usual cancellation. Speaking of which, Shade also provides notch-shaped comb filters to make the effect even more apparent.

Other than comb filtering, the plugin features a phaser filter shape that has three preset dips/resonance in the frequencies. You can use the onboard modulators to animate the filters and create a flanger and chorus effect. We’ll get more into these in the next section.

UVI Shade - The 5 Best Comb Filter & Resonator Plugins | Integraudio.com

Key Features:

  • 35 Filters
    There are 35 filters divided into these categories: low-pass, high-pass, notch, band-pass, high shelf, low shelf, peak, phaser, comb, and special. While most of them are relatively ordinary, the last three are unique. For example, under the Special category, you’ll find tilt EQ and Xpander, of which the latter has 37 modes and three drive/saturation types.
  • Modulators
    The plugin has a dedicated modulator section where you can add an unlimited number of modulators. The modulator types include an Envelope, Figure, Follower, LFO, Macro, MSEG, Random, Spread, and an XY pad. You can assign a modulator to a parameter by right-clicking the parameter and selecting the modulator from the list. As an example, you can use the Macro modulator to control several parameters at once.
  • Stereo Processing
    Every band in this EQ offers several stereo modes: Stereo LR, Stereo MS, Left, Right, Mono/Mid, and Side. So, you could add filters only on the sides to create wide movements. Or, by filtering each side of the stereo channel independently, you could use the comb filter to generate pseudo-stereo effects in mono audio.
  • Effective
    Shade is full of helpful features that make this EQ user-friendly and practical. For example, you can specify the slope value of the spectrum analyzer. And for most filters, the slope steepness can reach up to an astounding 2,000 dB/oct., which is a blessing for mastering uses.
UVI Shade | Overview

UVI Shade | Post-production showcase

Compatibility:

UVI Shade is available for Windows 8 or higher and macOS 10.9 or higher, both 64-bit only. It comes in VST 2/3, AU, and AAX formats.

Summary:

The plugin is a comprehensive digital equalizer on steroids capable of detailed editing, mastering, and sound designing. Having a dedicated modulator section makes intricate sound designing quick and easy. Furthermore, with modulators such as the Follower, you can create rhythmic sounds side-chained to kicks. Overall, the plugin is worth a try without a doubt.

2. Tritik Moodal

More Info & Price (Trial Available)

With a highly complex resonance engine, Tritik Moodal can make any signal tremendously wide or extremely narrow. It offers expanded freedom for any sound sculpting while still valuing realism.

Moodal can do exciting modeling to spaces and objects by providing artifacts to affect the sounds in a mix. You can make a drum sample appear unworldly huge, or incredibly small with its many modern filters simulating reverberant spaces.

Its straightforward interface is excellent for easy and quick implementation; you can set up properties in the whole frequency range by using the practical and interactive three editable curves in the main panel.

Tritik Moodal - The 5 Best Comb Filter & Resonator Plugins | Integraudio.com

Key Features:

  • Three Frequency Curves
    The frequency curves displayed on the main panel of Moodal are extremely handy. Each has parameters to set Modal Density, Decay Time, and Gain of the resonant frequency in the signal. In all of them, the graphic organizes itself so that the vertical axis will determine the resonator quantity, decay time, and output. At the same time, the horizontal axis represents the frequency.
  • Spectral Constraint
    A handy feature is the Spectral Constraint. Its a parameter, that when active, will ascertain the fundamental frequency by constraining the probability function with the frequency knob. You can then set values for Inharmonicity, which creates a dissonant tonality when boosted, spreading the harmonics widely. You can also adjust values for Relaxation if the user wants a “cross-fade” between the harmonics imposed by the frequency ascertainment and the harmonics that weren’t.
  • Mastering
    The plugin offers a giant sonic presence with its Master Decay feature, which the user can set for up to ten seconds. You can also define an ideal distribution range of Resonators in the Width control. The Dry and Wet segments work intuitively. Tritik’s Moodal is extremely easy to use and can quickly improve any mix.

Compatibility:

This plugin is available for Windows 7 or higher 32-bit and 64-bit and macOS 10.7 or higher 64-bit only. It comes in VST 2/3AU, and AAX formats.

Summary:

Tritik’s Spectral Resonator Moodal is a must-have for sound designers who want innovative sound effects in any project. The plugin can shape sound in many unexpected ways; any instrument can go through a character sculpting when going through Moodal. With many customizable controls for resonators, the plugin will let you freely experiment with structures for coloring the reverberance of the sounds; things can sound huge or surprisingly small. In addition to that, Moodal is pretty friendly towards any device since it’s optimized to provide good CPU performance.

3. lmdsp Superchord Review

More Info & Price (Trial Available)

Superchord is an excitingly new plugin by lmdsp that emulates virtual strings’ resonation.

It can texturize your sound and create entirely new soundscapes. Superchord is made of 12 string resonators that can be pitched to any key or create any chord.

Moreover, you can pan each resonator individually across the stereo field for great depth and fatness results. The plugin also lets you play the effect as a MIDI instrument.

lmdsp Superchord - The 5 Best Comb Filter & Resonator Plugins | Integraudio.com

Key Features:

  • LFO
    Optionally, you can engage the low-frequency oscillator. This function can be synced and modulated to taste. It also has three Target modes, which modulate different controls: Frequency, Pitch, and Gain. This last one is being applied to the main output for tremolo effects. You can also change the shape of the LFO. The plugin offers classic waveforms, such as sine, triangular, saw, and square, as well as unexpected patterns. Some of these are Sample and Hold (s|h), which jumps to a random value on every cycle, and Shot emits spikes at random intervals.
  • Model Panel
    Located at the right of the resonators, these are the plugin base controls. Damping controls how much resonation occurs. Shimmer opens up the upper harmonics. Darkness is a low-pass filter that muffles the sound. Mistune controls the string’s relative tuning, helping emulate real-life strings. Feedback makes notes ring for a longer time, also increasing their fullness. Lastly, Coupling simulates how nearby strings would resonate sympathetically with each other.
  • Advanced Controls
    By clicking the button beside the Model name bar, you’ll access the advanced controls. These settings generate more subtle results on the sound and can create interesting special effects. Tracking controls how the resonators react to lower frequencies from the input signal. Pluck Position changes the sound according to the area of the string that’s being plucked. The three H.V. sliders adjust the horizontal to vertical polarization, with Damp H.V. creating a more complex decay envelope. Buzz simulates the humming sound generated by instruments with non-rigid string attachments.

Character and Sound: 

Superchord effortlessly offers organic resonation, but you also adjust the plugin’s parameters to make it sound otherworldly. The Saturation section gives you the ability to add saturation to each resonator individually or at the summed signal’s output. The saturation knob lets you dial in from soft, tube-warm saturation up to heavy, amplifier-like distortion.

LMDSP Superchord - Quick Demo

Compatibility: 

This plugin is available as a VST2, VST3, AU, and AAX for 64-bit Windows 7 and up and macOS 10.11 and higher.

Summary: 

Superchord is an amazing resonator plugin. Its rich set of controls and parameters allow you to take full advantage of the plugin’s high-quality emulations and put your creativity to use—a great tool for experimental producers looking for a different sound.

4. MeldaProduction MCombMB Review

More Info & Price (Trial Available)

The MCombMB by Melda Productions is a multi-band comb filter with extensive sound-shaping controls.

The plugin splits the audio into up to six frequency bands, each with four filters. You can easily adjust the frequency, gain, and panorama of each filter in the main view. If all this control is too much, you can choose to randomize your filtering. This option is available inside each filter or globally for complete randomization. As with most Melda plugins, you can access a settings menu for each section of the plugin that gives you more controls and possibilities.

MeldaProduction MCombMB - The 5 Best Comb Filter & Resonator Plugins | Integraudio.com

Key Features:

  • Band Editor
    On the outside, the band editor might seem like a simple frequency analyzer. However, it hides several essential features. As mentioned, you can add up to six bands in the MCombMB. These bands are divided in the band editor by a long vertical line. You can reposition each band by dragging its central dot or adjust its gain by dragging the horizontal line. At the bottom, the short vertical line allows you to change the band’s panorama when in stereo mode or its depth when in mid-side mode. In the band menu, you can thoroughly adjust each band’s crossover, redefine the bands you’re working with, create new bands, and include different types of analyzers on top of the frequency spectrum. All this helps you not only focus on where and how you want the plugin to act but also how much information you want from it.
  • Band & Filter Panels
    Below the Band Editor, you’ll find the band-selection area and the main comb-filtering controls. Use the arrows at the upper-right corner of this section to select the additional bands. For each band, you get four different filters. You can use all four or bypass a few. Alternatively, you can bypass an entire band to check how it sounds. You get a Dry/Wet knob that lets you blend the unprocessed signal back with the modulation. The Gain, Frequency, and Panorama knobs work individually with each filter, letting you shape the sound as you want. The Feedback knob controls the amount of processed signal that returns to the input, and it has a limiter of its own to avoid the typical feedback squeal. Attack and Release knobs are used to shape the feedback limiter. Finally, you also get high-pass and low-pass filters for the entire band, named Min and Max. This large set of controls lets you filter your sound in virtually any possible way.
  • Presets & Randomization
    The MCombMB comes with several factory-made presets, all with creative and intriguing names and functions. You can select a preset or Ctrl-click the preset grid to load a random preset. Alternatively, you can use the intelligent randomization features of the plugin to come up with unexpected results. You can apply the Random function by clicking on the dice icon, choosing to randomize the entire plugin’s settings or focus on bands and filters. You can also Ctrl-click the dice icon to restrain the engine so it only slightly randomizes the chosen parameters or Alt-click it, which will result in extreme randomization.

Character and Sound: 

The MCombMB doesn’t add any saturation to the sound, neither does it distort the output. The safety-net limiter prevents loud peaks generated by the frequency modulations from ever crossing unity gain. Furthermore, you can enhance sound quality with up to 16x of oversampling. It is a transparent plugin that responds cleanly to your settings.

MeldaProduction MCombMB teaser

Compatibility: 

This plugin is available for 32- and 64-bit PCs running Windows Vista or newer and 64-bit-only Macs running macOS 10.9 or higher. It is available in VST, VST3, AU, and AAX formats.

Summary: 

MCombMB is a thorough application designed to put all comb-filtering power in the hands of the user. The randomization engine and the hidden settings menus are the icings on this plugin’s cake—a versatile and user-friendly comb filter for the modern producer.
