# Batch Audio Normalize Normalize multiple audio files to a target peak level with consistent volume across the batch > Canonical page: https://elysiatools.com/en/tools/audio-batch-normalize - **Category:** Media - **Keywords:** batch, audio, normalize, peak, volume, level, loudness ## Overview The Batch Audio Normalize tool allows you to upload up to 10 audio files simultaneously and normalize their volume to a consistent target peak level. By adjusting peak levels, you can eliminate sudden volume jumps across different tracks and export them in formats like MP3, WAV, FLAC, or AAC while preserving original file names. ## Inputs - **Audio Files (up to 10)** (file): Select up to 10 audio files to normalize - **Target Peak Level (dB)** (number): Target peak level in dB (typically -0.1 to -3.0) - **Output Format** (select) - **Keep Original Names** (checkbox): Use original file names for normalized files ## When to use - When preparing a playlist or podcast episode compilation where tracks have varying volume levels. - When mastering multiple audio stems or voiceover recordings to ensure they all peak at a safe, consistent level like -1.0 dB. - When converting and leveling a batch of raw audio recordings into a unified output format like MP3 or WAV for distribution. ## How it works - Upload up to 10 audio files in formats such as MP3, WAV, FLAC, or M4A. - Set your desired Target Peak Level in decibels (dB), typically between -0.1 dB and -3.0 dB to prevent clipping. - Choose your preferred output format and decide whether to keep the original file names. - Process the files to analyze the peak amplitude of each track and apply the precise gain adjustment needed to reach the target level. ## Use cases - Standardizing voiceover tracks recorded across different sessions to a uniform -1.0 dB peak level. - Preparing background music tracks for a video project to ensure none of the tracks clip or sound excessively quiet. - Batch converting and leveling raw field recordings into web-ready MP3 files with consistent peak volumes. ## Frequently asked questions ### What is peak normalization? Peak normalization adjusts the gain of an entire audio file so that the highest peak reaches a specified target level, ensuring consistent maximum volume without altering the dynamic range. ### What target peak level should I use? A target peak level between -0.1 dB and -1.0 dB is standard for general audio distribution, while -2.0 dB or -3.0 dB is often preferred to prevent distortion during lossy compression. ### How many audio files can I normalize at once? You can upload and process up to 10 audio files in a single batch. ### Will this tool compress the dynamic range of my audio? No, peak normalization applies a uniform gain adjustment to the entire file, preserving the original dynamics and relative volume differences within each track. ### What output formats are supported? You can export your normalized audio files in MP3, WAV, FLAC, AAC, M4A, OGG, or Opus formats. ## Related tools - [AAC to M4A Converter](https://elysiatools.com/en/tools/aac-to-m4a): Convert AAC audio files to M4A (MPEG-4 Audio) format with quality and channel controls - [AAC to OGG Converter](https://elysiatools.com/en/tools/aac-to-ogg): Convert AAC audio files to OGG Vorbis format with quality and channel controls - [Audio Add Silence](https://elysiatools.com/en/tools/audio-add-silence): Add a specified duration of silence to the start or end of an audio file - [Audio Ambience Loop Generator](https://elysiatools.com/en/tools/audio-ambience-loop-generator): Extract the background ambience/room tone from a fragment and generate a seamless loop of any target length. - [Batch Audio Converter](https://elysiatools.com/en/tools/audio-batch-converter): Convert multiple audio files between different formats like MP3, WAV, FLAC, AAC, OGG, Opus with quality settings and batch processing - [Audio Beat Matcher](https://elysiatools.com/en/tools/audio-beat-matcher): Adjust tempo to match a target BPM - [Audio Change Bitrate](https://elysiatools.com/en/tools/audio-change-bitrate): Re-encode audio to a new bitrate while keeping the same format - [Audio Format Converter](https://elysiatools.com/en/tools/audio-converter): Convert audio files between different formats like MP3, WAV, FLAC, AAC, OGG with quality settings and volume adjustment ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free Raw PCM Audio Samples](https://elysiatools.com/en/samples/pcm-samples): Raw PCM s16le audio samples featuring nature ambience and relaxing music for waveform, playback, and conversion workflows ## Related content - [Audio Loudness, Dynamics, and Mastering Delivery](https://elysiatools.com/en/hubs/audio-mastering-loudness-workflows): Measure LUFS, true peak, and dynamics, apply suitable control, and verify podcast, broadcast, or music audio before delivery.
