Key Features

  • Five fixed-frequency EQ sections combine selected low-cut, low-end, midrange, high-shelf, and high-attenuation curves in one compact workflow
  • Hybrid voicing draws from Helios, Pultec, API, and Neve-style modules instead of modeling only one hardware equalizer
  • Compensated custom line amp adds a separate gain-and-character stage after the EQ moves
  • 4x oversampling is available from the Analog Obsession badge for cleaner high-drive processing
  • Version 3 adds a resizable interface from 50% to 200% plus touchscreen support
  • Current release supports macOS on Intel or Apple Silicon and Windows, with VST3, AU, and AAX Native/Audiosuite formats

Description

FRANK is Analog Obsession’s hybrid analog-style equalizer, combining a small set of fixed-frequency bands inspired by Helios, Pultec, API, and Neve designs. It is built for quick tonal moves: clearing low-end rumble, adding weight around the bass range, bringing midrange forward, and polishing the top end without opening a dense parametric EQ.

The current FRANK release keeps the five-band concept while adding a compensated line amp for extra level and color control. Its Analog Obsession badge enables 4x oversampling, so users can trade a little more CPU load for cleaner processing when pushing the line amp.

Version 3 adds a resizable, touch-friendly interface and current Apple Silicon and AAX support. The deliberately limited frequency choices make it most useful for broad, musical shaping rather than detailed resonance repair or fully flexible mastering EQ work.

The original discovery lead calls the plugin FRANK 2, but Analog Obsession’s active F-Bundle page now lists the maintained FRANK version 3 release and its macOS and Windows download actions. That current developer-controlled post is the configured external destination, rather than the obsolete third-party ZIP link from the directory listing.

Frequently Asked Questions

What makes FRANK different from a standard parametric EQ?

FRANK uses a small number of fixed, hardware-inspired bands rather than offering fully variable frequency and Q controls. It is designed for fast tonal shaping and color, so it is better suited to broad musical moves than to hunting down a narrow problem resonance.

Which classic EQ styles are represented in FRANK?

Analog Obsession describes the layout as selected frequency points from four familiar module styles: Helios for the low cut, Pultec for the low boost/attenuate and high attenuation, API for the mid band, and Neve for the high shelf. The result is a hybrid tool rather than a one-to-one clone of any single unit.

How do I turn on oversampling in FRANK?

Click the ANALOG OBSESSION label in the interface to engage 4x oversampling. The developer notes that this control is part of the current FRANK release; it can be useful when adding more line-amp color, although it uses more CPU.

Why does the source call it FRANK 2 while the download page says FRANK?

FRANK 2 was the 2022 release named in the discovery listing. Analog Obsession later published the current FRANK version 3 in the F-Bundle, so this listing routes to the maintained developer page rather than an old third-party archive.
