## Overview

The Audio Normalize (Peak) tool adjusts audio files to a specified peak level using a two-pass detection method, ensuring consistent volume without clipping.

## Inputs

- **Audio File** (file): Select an audio file
- **Target Peak (dB)** (number): -0.1
- **Output Format** (select)

## When to use

- When audio recordings have inconsistent volume levels across segments.
- Before publishing podcasts or videos to meet standard loudness requirements.
- When mixing audio tracks to balance peak levels for a cohesive final product.

## How it works

- Upload your audio file in a supported format such as MP3, WAV, or FLAC.
- Set the target peak level in decibels (dB); the default is -0.1 dB to prevent clipping.
- Choose the output format from options like MP3, AAC, M4A, OGG, Opus, FLAC, or WAV.
- The tool performs a two-pass analysis to detect the maximum volume and normalizes the audio to the target peak.

## Use cases

- Normalizing podcast episodes to ensure consistent volume for listeners.
- Mastering music tracks to meet streaming platform loudness standards.
- Adjusting audio levels in video projects for balanced sound mixing.

## Frequently asked questions

### What is audio normalization?

Audio normalization adjusts the volume of an audio file to a consistent level, typically targeting a peak value to avoid distortion.

### Why use a two-pass method for normalization?

Two-pass detection accurately measures the peak volume before normalization, ensuring precise adjustment to the target level without guesswork.

### What audio formats are supported for input and output?

Input supports common audio formats; output can be MP3, AAC, M4A, OGG, Opus, FLAC, or WAV.

### Can I normalize multiple audio files at once?

This tool processes one file at a time; for batch processing, consider using dedicated audio editing software.

### What does the target dB value mean?

The target dB is the desired peak level in decibels; values like -0.1 dB are standard to prevent clipping in digital audio.
