Filtre
Key Features
- 16 filter modes cover broad low-pass shaping, shelves, peak and notch work, ring modulation, and Moog-style color instead of locking you into one auto-filter flavor
- Three dedicated LFO sections let you animate filter frequency, output volume, and stereo balance independently for more complex motion than a single global mod source
- Standard waveforms plus a custom CST shape option make it easier to build deliberate rhythmic gating, pulsing sweeps, and less predictable movement patterns
- Hands-on controls for frequency, gain, resonance, volume, balance, and width help the effect stay musical while still reaching into more aggressive sound-design territory
- Resizable hardware-inspired interface scales cleanly across smaller laptop setups and larger studio displays
- Built-in preset handling makes it practical to save and recall usable movement chains once you dial in a strong filter and modulation combination
Description
Filtre by Cloudy Samples is a free filter and modulation effect for macOS and Windows that combines a 16-mode contour filter with three independent LFO lanes for cutoff, volume, and balance movement. It is aimed at reshaping static sounds quickly, from gentle analog-style sweeps to more obvious rhythmic gating and auto-pan style motion.
The official feature set leans more toward creative tone animation than corrective mixing. Alongside familiar low-pass and shelf behavior, the filter section reaches into Moog-style color, ring modulation, peak shaping, and notch-style options, so it can move from broad sweetening to obvious sound-design gestures without feeling like a one-trick auto-filter.
Where Filtre gets more interesting is the modulation side. Separate LFO sections for frequency, volume, and balance make it easy to build pulsing movement, stereo travel, and chopped textures, and the custom waveform option gives you more deliberate control than a basic synced triangle or square sweep.
The included preset system and resizable hardware-inspired interface keep it approachable, and the public ZIP currently ships both macOS and Windows builds in one archive with AU and VST3 formats. For producers who want fast motion, character, and filtering in a single lightweight effect, Filtre lands closer to a practical sound-shaping utility than a novelty giveaway.
Frequently Asked Questions
What kind of plugin is Filtre?
Filtre is an effect plugin, not an instrument. Its job is to reshape incoming audio with a multi-mode filter and three modulation lanes, so it fits best on existing synths, drums, loops, guitars, or buses rather than generating sound on its own.
Is Filtre more useful for sound design or corrective mixing?
Sound design and movement are the stronger use cases. The filter section includes more precise modes, but the overall design leans toward animated sweeps, pulsing textures, stereo motion, and character changes rather than transparent problem-solving EQ work.
What can the modulation section actually control?
Filtre gives you separate LFO modules for filter frequency, volume, and balance. That means one instance can handle cutoff sweeps, tremolo-style level movement, and auto-pan behavior at the same time, with standard shapes or a custom waveform for each lane.
How does the download and installation work right now?
Cloudy Samples currently exposes a direct public ZIP from its products page, so there is no signup gate on the file itself. The archive contains a Windows VST3 build plus macOS VST3 and AU builds, and the bundled manual points you to the usual VST3 and Components folders for installation.
