2. Blue Cat’s Audio Mixer

More Info & Price (Trial Available)

Top 7 Frequency Splitter Plugins 2024 To Separate Bands - 2024 Update

Blue Cat’s Audio MB7 Mixer is a plugin for digital audio workstations (DAWs) that allows you to create custom mixing and routing configurations.

It uses a multi-band mixing console and provides a range of features such as level and pan controls, mute and solo buttons, a built-in spectrum analyzer, and more for each frequency band. It allows you to split the spectrum into seven bands and create custom channel strip configurations for each band.

Key Features:

  • Parameter mapping

The MB7 allows you to map any of its parameters to external MIDI controllers so that you can control them with knobs, sliders, or buttons on a MIDI controller.

This feature is called “parameter mapping” or “MIDI learn.” Once the parameter is mapped, you can control the parameter’s value by moving the knob or slider on the MIDI controller.
This allows you to adjust the plugin’s parameters while the audio plays, which can be useful for live sound applications.

  • Dual Mode

The plugin has a Dual Mode feature, which allows you to apply different processing on a stereo input signal’s left and right channels. In this mode, the plugin creates two independent processing chains, one for the left and the right, allowing you to apply different effects, EQs, or other processing on each channel.

  • Interface

The MB7 has a user-friendly interface that allows you to navigate and adjust the various mixing and routing options easily. It’s divided into a mixer section, an input/output routing section, a global section, a modulation section, and a preset manager, making it easy to control and browse the plugin through these windows.

  • Effects

You can add effects on the seven bands/channels, ranging from the chorus, flanger, compressor, reverb, EQ, etc. That way, you can add interesting effects to one band or frequency range, not the entire spectrum. That allows for deep customizations and sound sculpting.

  • MACROs

The plugin includes a set of macro controls that allow you to quickly and easily adjust multiple plug-in parameters. These macro controls are essentially knobs or sliders that can be assigned to control multiple parameters of the plug-in simultaneously.

You can make global adjustments to the overall sound of your mix or create complex modulation effects without manually adjusting each parameter. The macro controls can be customized to control any combination of parameters and can also be automated within a DAW for precise control over the mix.


It is available in VST, AAX, and AU plugin formats, which are compatible with Windows and Mac operating systems.


One of the standout features of the MB7 Mixer is its built-in sidechain feature. This allows you to create sidechain compression effects, which are commonly used in music production to create a “pumping” effect in the bass or to make space for vocals in a mix.

Additionally, the plugin also includes the ability to route audio between the slots and the main output, which further increases the possibilities for audio manipulation.

3. Waves StudioRack (Our Pick)

More Info & Download

Top 7 Frequency Splitter Plugins 2024 To Separate Bands - 2024 Update

StudioRack, Waves’ plugin chainer, benefits die-hard Waves enthusiasts because it can host plugins from other manufacturers.

StudioRack is a plugin utility originally launched in 2014 by Waves and recently upgraded to allow users to create chains of plugins. The goal is to view them as a unified whole rather than a collection of unrelated plugins.

A processing chain for the vocals or the percussion bus is required. Alternatively, you may build a multi-effects rack to simultaneously process delay, reverb, and pitch shifting. StudioRack is perfect for projects like these.

Key Features:

  • Interface

StudioRack can be used like any other effect plugin in your favorite audio editing software. A plugin, parallel processing split, or multiband split can occupy each of the eight available slots in each instance. Copying and pasting plugins and presets are as simple as dragging and dropping.

If you need to flip the phase of the incoming signal, you can use the phase inversion button and adjust the input gain to keep the gain at unity. It’s convenient to access the volume control, peak reading, and gain attenuation meter immediately after the amplified signal.

  • Parallel Processing

Multiband channels can be separated using the plugin, supporting as many as five separate frequency bands per instance. It’s now possible to make your multiband plugins with this method.

In addition, you can use the bands to apply different plugins, such as a distortion effect to the highs and a saturation effect to the midrange. You can fine-tune the crossover point by adjusting the frequency difference between the channels, though there is no graphical representation of this information.

In the same way, you may adjust the volume and stereo balance independently for each.

  • Macros

Since StudioRack can store many plugins, it could become unmanageable if too many were to be kept in one area. So, in a pleasant twist, it comes with eight customizable macros that you can use to keep everything under control.

The Apply button on the macros panel, the plugin controls, and the macros knob are the three ways to assign plugin features to macros. Macros transform StudioRack from a simple utility plugin into a flexible multi-effects rack.

The possibilities are exciting, ranging from offering quick access to, for example, the amount of compression in a vocal chain to delay, reverb or other effects in a chain applied to a breakdown.

  • More Processing Power

You can use as many plugins as you like while mixing intensive sessions without worrying about crashing your computer. StudioRack facilitates the migration of plugin processing from a local PC to a high-powered SoundGrid DSP server whenever you’re ready to switch.

You can offload all of the plugins in a given StudioRack channel’s chain with a single mouse click. StudioRack can be used with only your computer or with DSP offload via SoundGrid, depending on your needs and preferences. Find out how to use StudioRack in a SoundGrid environment.


The OS requirements for this plugin are Windows 7 or higher for PC and macOS 10.9 or higher for Mac. It comes in VST/RTAS/AU/AAX formats and supports 32 and 64 bit systems.


If you use many digital audio workstations, SudioRack is a good tool for coming up with chain mix ideas that you can easily transfer between them.

The plugin’s multi-band capabilities make it even more potent, and its stereo imaging functionality, which works even without loaded plugins, helps the system conserve resources. Thanks to Waves for providing StudioRack at no cost to the public.

Frequency crossover splitters are a great way to increase the quality of your audio signal. The Frequency Splitter’s routing is its most perplexing feature.

Because the signals carried by “MAIN OUT” and “SENDS” are identical, you might send the same signal to different parts of your sound system. The “SENDS” could be used for different purposes, like creating a separate monitor mix or feeding a recording device, while the “MAIN OUT” feeds the main PA.

You can use the crossover to route low frequencies to one destination and high frequencies to another. That way, you can optimize your sound system for each range of frequencies.

When you master Frequency Splitter’s routing options, you’ll unlock a wealth of possibilities in high-level signal processing.
