TP-1 Tone Purifier

TP-1 Tone Purifier is a source cleanup plugin that combines three essential restoration tools — a LEARN-based Noise Reducer, a Dynamic Resonance Suppressor, and a 4-band EQ — into a single, streamlined workflow.

Recorded audio rarely arrives clean. Room tone, HVAC hum, mic self-noise, and unwanted resonances accumulate between the source and the mix, stealing clarity before the first plugin even opens. TP-1 is designed to handle these problems upstream, in one pass, so the rest of your chain can focus on creative processing.

One-Click Learn

Engage LEARN on a silent section of your recording, and TP-1 automatically captures a noise profile and adapts its reduction engine to the source. No manual threshold-hunting, no band-by-band tuning. Built-in stability detection keeps the profile reliable even when the "silent" section isn't perfectly silent.

Intelligent Noise Reduction.

A single NOISE knob takes you from subtle cleanup to aggressive removal. The engine is tuned to preserve transients, protect low-end fundamentals, and adapt to changing signal conditions in real time — so reduction stays musical across a wide range of material, from dialogue to full-band recordings.

Dynamic Resonance Suppressor

A dedicated suppressor that targets harsh peaks, room modes, and mic resonances across a user-defined frequency range (low and high bounds). Useful for taming boxy rooms, piercing sibilance, and resonant instruments without dulling the source.

4-Band EQ with Musical Ranges

Two shelves and two fully parametric peaks, tuned for corrective work on typical problem ranges. Drag handles on the spectrum, use the mouse wheel for Q, or double-click to toggle a band on/off — all gestures register as DAW automation, so nothing is lost in undo/redo.

Real-Time Spectrum Analyzer

Input (cyan) and output (orange) overlaid on the same display, with the EQ curve visualized in-context. See exactly what you are removing, at a glance.

DELTA Monitoring

Solo the removed signal — noise, resonance, or both — to verify that you are only subtracting what you intend to. Essential for avoiding over-processing.

Applications
