McDSP FilterBank
McDSP FilterBank

FilterBank is a high-end equalizer plug-in designed to emulate the sounds of vintage and modern equalizers and filters.

McDSP FilterBank, McDSP’s first product, is an equalizer plug-in that rivals any analog EQ with its flexible design and substantial feature collection. For example, emulate any EQ (tube-driven or solid-state, vintage or modern, fat or thin), or be used to create a distinct custom EQ. In addition, FilterBank includes updated hardware compatibility, a modern high-definition user interface, over 1,500 additional presets, zero-latency algorithms, and double-precision processing.

FilterBank has three plug-ins: E606 (parametric, high and low shelving EQ, high and low pass filters), F202 (steep high and low pass filtering with resonant Q control), and P606 (P606 – parametric EQ with variable Q modes). Since its debut in 1998, FilterBank has become a legend within the audio community. With its unique Peak, Slope, Dip controls, and variable Q modes, FilterBank also emulates any EQ. In other words, use it to create a distinct custom EQ.




You can literally get under the hood in the E606 and adjust the fundamental algorithm circuit for low and high shelving EQ. Control the overshoot (Peak), the transition (Slope), and the undershoot in the shelving EQ response.

Phase is Back!

Make polarity (phase) adjustments for the left and right channels – independently!


Use the Real-Time Analyzer to monitor how the frequency spectrum is being affected.

The McDSP FilterBank v5 plug-in is a collection of 3 different EQ and filter configurations. Of these configurations, the E606 has an unique shelving EQ control set called Peak, Slope and Dip. These controls allow the user to customize the shelving EQ in a way only previously available to the EQ designers.

This issue focuses on the shelving EQ Peak, Slope, and Dip (PSD) control set and how they can be used in audio production.

Peak Slope and Dip Basics

Peak is the over shoot in the boost/cut portion of the shelving EQ frequency response. Peak is useful in adding ‘punch’ to the shelving EQ. A little bit of overshoot in the shelved band really helps the effect of the shelving EQ come through a mix. A judicious amount of Peak might offset the need for more shelving gain, and can allow the user to combine a shelf and nearly parametric response into a single band of EQ.

Dip is the under shoot in the non-boost/cut (i.e. the flat unaffected portion) of the shelving EQ frequency response. Dip works well to mask away the non-shelved portion of the frequency spectrum just above a low shelf boost (or just below a high shelf boost). As you increase the presence of some frequencies, it’s a good idea to reduce the amount of signal content just above/below the shelving response. This allows you to boost less because you are also cutting away some portion of the frequency spectrum – almost like an intelligent EQ!

Slope is the transition between the shelved and non-shelved portion of the frequency response. A more gradual Slope setting (50% or less) gives a smoother response – nice for boosting the high end of a piano track. Steeper Slope settings (75% and greater) provide a tighter response – good for bringing out kick drums or hi-hats. Note that the effect of the Peak and Dip controls is reduced as the Slope becomes more gradual. Peak and Dip have no effect on the shelving EQ shape when the Slope control is at its minimum setting (0%).

Peak Slope and Dip Applications

FilterBank is still, nearly 8 years after its release, the only EQ in hardware of software to offer the user complete control over the basic design elements of any shelving EQ with its unique Peak, Slope, and Dip controls. What does this mean for audio production? Here are some examples.

Kick and Snare separation

Typical music styles call for a good ‘thud’ from the kick drum. A good solution for such sounds is a low shelf EQ. But as the kick is being boosted, the snare sound should not get the same treatment. For that matter, the ‘thud’ of the kick should not compete with the ‘thwack’ of the snare. Using the low shelf, the kick is boosted for a nice ‘thud’.

Hi-Hat, Cymbals

The Peak, Slope, and Dip controls are not only good for getting surgical as in the above example. These controls can allow the same shelving EQ gain and frequency settings to have a variety of tones. In the examples below the same drum kit is processed with some high shelf EQ, but with different variations of Peak, Slope, and Dip.

Classical Guitar Air

Some folks refer to the high shelf boost as adding ‘air’ to a track. As shown with the Hi-hat and Cymbals example above, a variety of tones are obtained using the Peak, Slope, and Dip controls in FilterBank.

McDSP System Requirements

McDSP HD and Native plug-ins are compatible with Pro Tools, Logic Pro, Cubase, Nuendo, FL Studio, Ableton Live, LUNA, Reaper, Sonar, Studio One, and other DAWs that support AAX, AU, and/or VST3 plug-in formats.

Note as of v7.0, VST is no longer supported. VST versions of v6 McDSP plug-ins will no longer be updated, and will be uninstalled.
McDSP Native plug-ins support AAX Native, AU, and VST3 plug-in formats.

McDSP HD plug-ins additionally support the AAX DSP plug-in format, as well as AAX Native, AU, and VST3 plug-in formats.

McDSP plug-ins support Mac OS 10.13.x (High Sierra), 10.14.x (Mojave), 10.15.x (Catalina), 11.x (Big Sur), 12.x (Monterey), 13.x (Ventura), 14.x (Sonoma), and Windows 10 & 11.

Mac OS version 10.12.x (Sierra) may work, but is not officially supported.
Earlier Mac OS versions are not officially supported.

McDSP plug-ins run natively on Intel and Apple silicon processors.

McDSP plug-ins require an iLok2 or iLok3 USB Smart Key, or an iLok License Manager account and an iLok Cloud session for authorization. Each McDSP v7 plug-in contains two activations per authorization.

McDSP HD plug-ins also support the VENUE S6L systems. Note McDSP VENUE plug-ins are packaged in a VENUE specific installer available on the McDSP web site.

What’s new in V7.2 (December 2022)?

The latest v7 release from McDSP now includes support for both Intel and Apple silicon processors for the entire McDSP AAX plug-in product line. McDSP AAX plug-ins are universal binaries, and will run natively on either Apple hardware platform, once Pro Tools Apple silicon support is available.

What’s new in version 7.0?

McDSP’s v7 is the latest generation of McDSP’s professional audio plug-ins. McDSP’s v7 release brings tons of new and exciting features to our entire line of software products, along with amazing high-definition user interfaces. For over two decades our award-winning double precision, zero latency algorithms have stood out from the crowd, and v7 continues this legacy, adding 1500+ additional presets and two activations per license or subscription. All McDSP v7 plug-ins are also optimized for Apple silicon and the latest Intel processors.
