Frequently Asked Questions

What does audio normalization do?

Audio normalization adjusts the volume of an audio file so that its peak amplitude reaches a target level. This ensures consistent loudness across different recordings without introducing distortion.

What is the recommended target level?

For broadcast and streaming, -1 dB is the standard target. For music production, -3 dB to -6 dB provides more headroom. For maximum loudness, 0 dB can be used but leaves no headroom.

Does normalization reduce audio quality?

No. Normalization is a simple gain adjustment that scales all samples proportionally. It does not compress, limit, or alter the dynamic range of your audio.

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device, ensuring 100% privacy.
