- Selectable 1-to-4 filter stages adjusting the cutoff slope from gentle 6 dB/octave to steep 24 dB/octave
- Resonance control capable of self-oscillation for generating tones without any input signal
- Independent envelope follower per channel with attack and release controls for dynamic auto-wah effects
- Switchable low-pass and high-pass filter modes for versatile tonal shaping
- Full MIDI CC automation and joystick control of all parameters for live performance flexibility
Description
Naive LPF by Admiral Quality is a resonant low-pass and high-pass filter plugin modeled after real analog circuitry. Rather than relying on standard digital filter algorithms, it closely replicates how analog filter circuits behave, producing a warm, slightly distorted character that sounds distinctly musical on individual instrument tracks.
The filter offers continuously variable cutoff frequency ranging from far above the host sample rate down to 0 Hz, with selectable 1-to-4-stage slopes for adjusting steepness from gentle roll-off to sharp 24 dB/octave cuts. Resonance can be pushed into self-oscillation, generating tones even without an input signal present.
A dedicated envelope follower on each of up to six independent channels enables dynamic auto-wah effects, with separate attack and release controls shaping how the cutoff responds to input dynamics. Full MIDI CC automation and even joystick control of all parameters make it highly flexible for live performance and creative sound design.
Admiral Quality originally built Naive LPF as a technology test-bed for their paid SCAMP synthesizer, and it shares the same core filter engine. Despite its prototype origins, the plugin earned a devoted following for its organic tone quality and has been described as a secret weapon for taming harshness and softening high frequencies in a natural, analog-flavored way.
Note that Naive LPF is a legacy 32-bit VST 2.3 plugin for Windows only, and Admiral Quality no longer actively supports or updates it. A 32-bit-compatible host or bridging solution such as jBridge is required for use in modern 64-bit DAW environments.

Frequently Asked Questions
Does Naive LPF work in 64-bit DAWs?
Naive LPF is a 32-bit VST 2.3 plugin, so it requires a 32-bit compatible host or a bridging tool like jBridge to run inside modern 64-bit DAWs. Admiral Quality recommends their newer SCAMP plugin for full 64-bit and AU compatibility.
What is the difference between Naive LPF and Admiral Quality's SCAMP?
Naive LPF shares the same core analog-modeled filter engine as SCAMP but with fewer features. SCAMP is a full synthesizer with additional oscillators, effects, and modern format support (64-bit VST/AU), while Naive LPF focuses solely on the filter and envelope follower in a lightweight 32-bit VST package.
Can Naive LPF self-oscillate like a hardware analog filter?
Yes. When the resonance is turned up high enough, Naive LPF enters self-oscillation and produces audible tones even with no input signal. This behavior closely mimics classic analog filter circuits and can be used creatively as a sine-wave tone generator.
How does the envelope follower work across multiple channels?
Naive LPF provides an independent envelope follower for each of its six channels, allowing the cutoff frequency to respond dynamically to the amplitude of each channel's input signal. The attack and release controls let you shape how quickly the filter reacts, enabling everything from subtle dynamic filtering to pronounced auto-wah sweeps.
