- **Category:** Media

- **Keywords:** audio, dynamics, broadcast, gate, compressor, limiter

## Overview

Applies a noise gate, gentle compression, and a limiter for consistent broadcast loudness.

## Inputs

- **Audio File** (file): Select an audio file
- **Gate Threshold (dB)** (number): -45
- **Gate Ratio** (number): 3
- **Compressor Threshold (dB)** (number): -18
- **Compressor Ratio** (number): 3
- **Compressor Attack (ms)** (number): 5
- **Compressor Release (ms)** (number): 120
- **Limiter Ceiling (dB)** (number): -1
- **Output Format** (select)

## When to use

- When preparing audio for broadcast to meet loudness standards.
- When editing podcasts to ensure consistent volume levels across episodes.
- When processing voiceovers to reduce background noise and even out dynamics.

## How it works

- Upload your audio file in a supported format.
- Adjust the gate, compressor, and limiter settings as needed.
- Select the output format and process the audio.
- Download the processed file with consistent dynamics.

## Use cases

- Normalizing podcast audio for a consistent listening experience.
- Preparing radio segments to comply with broadcast loudness regulations.
- Enhancing voiceover recordings by reducing noise and balancing levels.

## Frequently asked questions

### What audio formats are supported?

The tool accepts common audio formats like MP3, WAV, AAC, and more, with a file size limit of 200 MB.

### Can I use default settings?

Yes, default parameters are optimized for broadcast, but all settings are customizable.

### How does the noise gate help?

It silences audio below the threshold, reducing background noise during silent parts.

### What does the compressor do?

The compressor reduces the dynamic range, making loud parts quieter and quiet parts louder for a more even sound.

### Why is the limiter important?

It prevents audio peaks from exceeding the ceiling, avoiding distortion and ensuring safe levels for broadcast.
