About this tool
- 1
Upload Audio
Select an audio file you want to normalize from your device.
- 2
Choose Target Level
Set the target loudness level in dB (e.g., -14 LUFS for streaming platforms).
- 3
Select Mode
Pick between peak normalization, RMS normalization, or loudness (LUFS) normalization.
- 4
Process & Download
Click normalize and download the volume-adjusted audio file.
- Use -14 LUFS for Spotify and Apple Music, -16 LUFS for podcasts.
- Peak normalization is fastest but LUFS gives more perceptually consistent results.
- Normalize before applying other effects like EQ or compression for best results.
- Compare the before and after waveform to verify the adjustment looks correct.
- Peak, RMS, and LUFS normalization modes
- Adjustable target loudness level with dB precision
- Real-time loudness metering before and after processing
- Batch normalization for multiple files at once
- Preserves original audio quality and format
- Preparing podcast episodes to meet platform loudness standards
- Leveling volume across multiple tracks in a playlist or album
- Fixing quiet recordings from meetings or interviews
- Ensuring consistent volume for audiobook chapters
Peak normalization adjusts based on the loudest sample, while LUFS measures perceived loudness over time, giving more consistent results across different audio content.
No. Normalization scales the amplitude uniformly and does not add compression or distortion. The audio quality remains intact.
YouTube normalizes to approximately -14 LUFS. Setting your target to -14 LUFS prevents YouTube from further adjusting your audio.
