TP-1
TONE PURIFIER
Noise reduction, resonance suppression, and EQ in a single plugin that cleans up the tone of your source.
v1.0.3
3-in-1
Noise reduction, resonance suppression, and a 4-band EQ in a single plugin
One LEARN Button
Play your source for 8 seconds and TP-1 captures the noise profile automatically
Product Description
TP-1 is a plugin that learns the noise in your source and applies noise and resonance processing.
It unifies noise reduction, a resonance suppressor, and a 4-band EQ, letting you set the amount of noise removal intuitively.
The LEARN function captures the noise profile of the source, so you can remove background noise without compromising musicality. It works for studio production and for post-processing live recordings.
Features
01
One-Click Learning
Press LEARN and play back your source. TP-1 automatically captures a noise profile. No complex spectral setup required; you are ready to clean up.
02
4-Band EQ
Tame unwanted lows and harsh frequencies precisely so the source comes through.
03
Noise Reduction
Using the captured profile, TP-1 applies spectral subtraction that targets the background noise. Dial the removal strength in real time with the NOISE knob while keeping the musicality of your source intact.
04
Resonance Suppressor
Detects and attenuates resonant peaks caused by the room or mic, without sacrificing attack or clarity.
Detailed Specs
- Automatic noise-profile learning (8 sec)
- Spectral-subtraction noise reduction (NOISE knob for amount)
- Dynamic resonance suppression (up to -12 dB)
- 4-band EQ (20 Hz–20 kHz / Q 0.1–10 / ±18 dB)
- EQ Band 1 / 4 switchable between HPF / LPF / Peak
- Real-time spectrum display
