What Is Audio Normalization?
Audio normalization adjusts the volume of an audio file so that its loudest point (peak) reaches a specified target level — typically -1 dBFS (decibels relative to full scale). This ensures consistent playback volume across different files.
Unlike compression, normalization is a linear gain adjustment — it preserves the dynamic range of the original audio while making it louder or quieter overall.
Key Features
- Peak normalization: adjusts gain so the loudest sample hits the target level
- Adjustable target level from -20 dBFS to -0.1 dBFS
- Live waveform visualization of the input audio
- Displays peak and RMS levels before processing
- Output as lossless WAV — no quality loss
- Preview normalized audio before downloading
- 100% browser-based using the Web Audio API
Common Use Cases
- Boosting the volume of a quiet voice recording or podcast
- Making multiple audio files the same volume before mixing
- Preparing audio for uploading to YouTube, Spotify, or social media
- Fixing recordings made with different microphones at different volumes
- Quick loudness check before professional mastering
Frequently Asked Questions
Is my audio file uploaded to a server?
No. Audio processing uses the Web Audio API entirely within your browser. Your file never leaves your device.
What audio formats are supported?
MP3, WAV, OGG, AAC, FLAC, and any format supported by your browser's Web Audio API.
What does normalization do?
Normalization adjusts the overall volume so the loudest sample reaches the target level. This is a lossless, linear gain change that preserves dynamic range.
What format is the output?
The output is a WAV file. WAV is lossless and universally compatible. You can convert it to MP3 afterwards using our Audio Converter tool.
