## Overview

Detects low-frequency burst regions, then renders a repaired copy with high-pass cleanup, low-band attenuation, compression, and limiting. Use it for podcast, audiobook, video dialogue, and voice-over recordings where P/B consonants overload the mic.

## Inputs

- **Audio File** (file): Select an audio file
- **Reduction Mode** (select)
- **Plosive Sensitivity** (range)
- **Low Cut Frequency (Hz)** (number)
- **Keep Warmth** (checkbox)
- **Output Format** (select)

## When to use

- When close-mic vocal recordings suffer from distracting low-frequency thumps caused by P and B plosive sounds.
- When editing podcast episodes, audiobooks, or voice-overs where speakers did not use a physical pop filter.
- When you need to clean up dialogue tracks for video projects without stripping away the natural warmth and body of the speaker's voice.

## How it works

- Upload your audio file and select your desired reduction mode, such as light, podcast, or aggressive.
- Adjust the plosive sensitivity and low cut frequency to target the specific low-frequency burst regions.
- Enable the warmth preservation option to protect the natural body of the voice during attenuation.
- Process the file to apply high-pass cleanup, compression, and limiting, then download the repaired audio in your chosen output format.

## Use cases

- Repairing podcast interviews recorded with budget microphones or without pop filters.
- Cleaning up voice-over tracks for audiobooks to meet strict distribution quality standards.
- Polishing video dialogue tracks where wind or close-mic placement caused low-frequency thumps.

## Frequently asked questions

### What audio formats are supported for output?

You can export your processed audio as MP3, WAV, FLAC, M4A, or OGG.

### How does the Keep Warmth option work?

It prevents the tool from over-filtering the lower frequencies of the voice, ensuring the speaker still sounds natural and full-bodied.

### What is the difference between the reduction modes?

Light is for minor cleanup, Podcast is optimized for standard speech, and Aggressive targets heavy P/B thumps.

### Can I adjust the frequency threshold for the low-cut filter?

Yes, you can set the low cut frequency anywhere between 40 Hz and 220 Hz.

### Will this tool remove background noise?

No, this tool specifically targets low-frequency plosive bursts (P/B sounds) rather than general background noise.
