What is the Audio Normalizer?
✔ The Audio Normalizer is a tool that adjusts the volume of audio files to ensure a consistent loudness level.
✔ It supports RMS, dB, and EBU R128 normalization.
2. Which audio formats are supported?
✔ The Audio Normalizer supports all common audio formats, including WAV, MP3, FLAC, and AAC.
2. Normalization Methods
3. How does RMS normalization work?
✔ RMS (Root Mean Square) normalization adjusts the average loudness level of an audio file to a specific value.
✔ The signal is evenly amplified or reduced to maintain a consistent listening experience.
4. What is dB normalization?
✔ dB normalization adjusts an audio file’s volume to a predefined decibel level.
✔ Useful for correcting very loud or very quiet recordings.
5. What is EBU R128, and why is it important?
✔ EBU R128 is an international loudness standard used in broadcasting and professional audio.
✔ It measures loudness in LUFS (Loudness Units Full Scale), ensuring consistent volume across multiple files.
3. Upload & Processing
6. Can I normalize multiple files at once?
✔ Yes! The Audio Normalizer supports batch processing for multiple audio files.
7. How do I upload a file?
✔ Click "Select Files" to upload audio files.

✔ Yes! A progress bar shows the status of the normalization process.
13. What is the difference between Peak and RMS normalization?
✔ Peak Normalization ensures that the loudest part of the file does not exceed a set threshold.
✔ RMS Normalization adjusts the overall average volume of the file.
14. Can I apply different settings for each file?
✔ Yes! You can set individual RMS or dB values for each file.
