# LoFlow

A professional-grade low pass filter VST3 and AU plugin for creating smooth transitions and creative filter effects.

## Overview

LoFlow is a lightweight, CPU-efficient plugin that provides precise control over filtering transitions. Whether you're producing electronic music, sound design, or mixing, LoFlow offers the essential tools for smooth filter manipulation.

## Features

- **Frequency Control**: Precise cutoff control from 20Hz to 20kHz
- **Resonance Shaping**: Fine-tune the filter's character
- **Mix Control**: Blend between dry and filtered signals (0-100%)
- **Output Level**: Final gain adjustment for perfect levels
- **Response Display**: See the filter curve, and drag it to set frequency and resonance at once
- **Zero Latency**: Real-time processing with no delay
- **CPU Efficient**: Optimized for minimal system resource usage

## Controls

- Drag a knob up or right to turn it up. Hold Shift for fine adjustments.
- Double-click a control, or Option-click (Alt-click on Windows), to reset it.
- Double-click a value to type one, for example 2.5k for 2.5 kHz or -3 for -3 dB.
- Drag the corner of the window to resize it from 75% to 200%. LoFlow remembers the size.
