Guide to Volume and Normalization

Understand how audio gain works and avoid distortion.

What is Clipping and How to Avoid It?

When amplifying audio, if the volume exceeds the digital limit (0 dB), clipping or saturation occurs, generating metallic noises. DuneTools allows you to preview and adjust gain carefully to maintain clean sound.

💡

We recommend not exceeding 200% if the original audio is already loud.

Normalization vs Simple Gain

Our tool applies a linear gain directly onto the waveform. This is ideal for leveling tracks that are too quiet without complex mastering processes.
