Just A Filter
Key Features
- Provides five single-band shapes: low shelf, low cut, notch, high cut, and high shelf.
- Uses a cutoff control spanning 20 Hz to 20 kHz for broad roll-offs, targeted notches, and shelving work.
- Offers linear Q for direct bandwidth control and proportional Q that narrows as gain is pushed further.
- Covers filter gain from -12 dB to +12 dB for corrective cuts and broad tonal boosts.
- Includes a quality toggle that switches from normal processing to 8x oversampling.
- Adds a phase-flip toggle and trim output control for checking polarity and matching level after processing.
- Keeps all essential filter controls in a focused one-band interface for quick decisions.
Description
Just A Filter is a compact single-band multimode filter EQ from ViatorDSP for broad tonal shaping without the overhead of a full parametric equalizer. It combines low-shelf, low-cut, notch, high-cut, and high-shelf modes with gain, bandwidth, and cutoff controls that cover the core filter moves needed on a track.
The Q control can work in a conventional linear mode or in proportional mode, where the bandwidth narrows as the magnitude of the gain increases. That proportional response is designed to echo the behavior of hardware EQs such as the API 560, making gentle boosts and cuts feel different from more pronounced moves.
A quality switch enables 8x oversampling when a higher-quality processing mode is wanted, while a phase-flip control and added trim output control help place the result cleanly in a session. The 20 Hz to 20 kHz cutoff range makes the same simple interface useful for low-end cleanup, high-end roll-off, notch work, and broad shelving.
Just A Filter suits fast corrective or characterful filter decisions where one clearly labeled band is more useful than a large channel strip. ViatorDSP provides it as a public Mac Universal and Windows VST3 download on the product post.
Frequently Asked Questions
What filter types does Just A Filter include?
Just A Filter offers low-shelf, low-cut, notch, high-cut, and high-shelf modes. The cutoff control covers 20 Hz to 20 kHz, so the same band can handle both broad tone shaping and more targeted filtering.
What is the difference between linear and proportional Q?
In linear mode, the bandwidth dial changes the filter bandwidth directly. In proportional mode, ViatorDSP says the bandwidth is affected by filter gain: smaller gain moves are wider and larger positive or negative moves become narrower, following the behavior of hardware EQs such as the API 560.
Does Just A Filter include oversampling?
Yes. Its Quality control selects normal processing with no oversampling or a High setting with 8x oversampling.
Which systems and plug-in formats are listed?
ViatorDSP lists a Mac Universal build and Windows 10 VST3. The discovery listing also identifies the Mac release with VST and AU availability; use the official product post for the current installer choices.
