Viator DSP Just A Filter v1.0.0 VST3 AU x64 WiN macOS [FREE]

Viator DSP Just A Filter is a free, single-band filter EQ for producers who want straightforward frequency shaping without a full multiband equalizer. Use it to reduce low-end rumble, soften high frequencies, notch out a problem area, or adjust the tonal balance with a shelf. Five filter types are available: low-shelf, low-cut, notch, high-cut, and high-shelf.

The cutoff covers 20 Hz to 20 kHz, while filter gain ranges from -12 to +12 dB. Linear Q mode gives you direct bandwidth control. Proportional Q instead links bandwidth to gain: gentle adjustments stay broad, and stronger boosts or cuts become narrower. In that mode, the bandwidth dial is inactive, providing a gain-dependent response inspired by hardware EQ designs.

Normal quality runs without oversampling; High quality enables 8x oversampling. A polarity-invert switch and output trim provide additional level and signal control.

Just A Filter suits hobby producers looking for focused EQ adjustments in a compact tool. The Windows 10 VST3 version fits compatible hosts such as FL Studio and Ableton Live; a universal Mac build is also listed.
