# Audio RMS Normalize Normalize audio based on its RMS level > Canonical page: https://elysiatools.com/en/tools/audio-rms-normalize - **Category:** Media - **Keywords:** audio, normalize, rms ## Overview The Audio RMS Normalize tool adjusts audio files to a consistent loudness level based on RMS (Root Mean Square) measurements, ensuring uniform volume across recordings for improved listening experiences. ## Inputs - **Audio File** (file): Select an audio file - **Target RMS (dBFS)** (number): Typical values: -23 (Broadcast/Quiet), -20 (Balanced), -18 (Audiobooks/Loud) - **Max Gain (dB)** (number): 18 - **Gating Threshold (dBFS)** (number): -50 - **Output Format** (select) ## When to use - When you need to standardize loudness across multiple audio files for podcasts, playlists, or mixed media. - When preparing audio for broadcast or streaming platforms that require specific loudness standards. - When mixing audio tracks to achieve balanced volume levels without manual adjustment. ## How it works - Upload an audio file in a supported format such as MP3, WAV, or AAC. - Set the target RMS level in dBFS, with common values like -20 for balanced audio or -23 for broadcast. - Optionally adjust the maximum gain and gating threshold to control normalization intensity. - Select the output format and download the normalized audio file. ## Use cases - Normalizing podcast episodes to maintain consistent volume for listeners across different recordings. - Adjusting background music in video projects to match dialogue levels without manual editing. - Preparing audio files for e-learning courses to ensure clear and even sound throughout. ## Frequently asked questions ### What is RMS normalization? RMS normalization adjusts audio based on its average loudness level, measured in dBFS, to achieve consistent volume across files. ### What audio formats are supported for upload? You can upload audio files in formats like MP3, WAV, AAC, OGG, FLAC, and more, as specified in the tool options. ### Can I normalize multiple audio files simultaneously? This tool processes one file at a time. For batch normalization, upload and process files individually. ### What does the gating threshold do? The gating threshold sets a dBFS level below which audio is ignored during RMS calculation, preventing quiet sections from skewing results. ### How do I choose the right target RMS level? Select based on your use case: -23 dBFS for broadcast, -20 dBFS for general balance, or -18 dBFS for louder content like audiobooks. ## Related tools - [Audio Interview Level Matcher](https://elysiatools.com/en/tools/audio-interview-level-matcher): Match loudness between a host and a guest track (or any two voice takes) while preserving natural dynamics. - [Audio Label Split](https://elysiatools.com/en/tools/audio-label-split): Split audio based on an Audacity-style label file - [Assistive Listening Enhancer](https://elysiatools.com/en/tools/audio-assistive-listening-enhancer): Clarify listening audio with low-frequency cleanup, speech-presence EQ, conservative denoising, and level protection. - [Audio Chapter Split](https://elysiatools.com/en/tools/audio-chapter-split): Split an audio file based on its chapters/metadata - [Audio Key Change for Singers](https://elysiatools.com/en/tools/audio-key-change-for-singers): Transpose a song by key or semitones while preserving its duration and speed. - [Audio Overlay](https://elysiatools.com/en/tools/audio-overlay): Overlay one audio track on top of another at a specific time - [Audio Spectral Filter](https://elysiatools.com/en/tools/audio-spectral-filter): Filter audio based on its spectral content - [Video Audio Volume](https://elysiatools.com/en/tools/video-audio-volume): Adjust the audio volume in a video file by increasing, decreasing, or normalizing sound levels ## 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.
