Audacity: Normalize vs Amplify comparison

Dewi Jenkins·Apr 2026

Demo summary

The narrator compares the Amplify and Normalize effects side-by-side on the same track to show the difference in peak handling.

Step-by-step

Highlight the entire audio track
Go to Effect and select Volume and Compression
Select Amplify
Adjust the amplification value (e.g., to 10.1)
Click Apply to see the bolded peaks
Undo the effect to test the alternative
Go back to Volume and Compression and select Normalize
Click Apply and compare the sharpness of the peaks to the Amplify effect

Options

Adjust amplification decibels to a custom level like 10.1 instead of the default

Tips

Use Amplify over Normalize to get smoother, less harsh audio peaks
Aim for around 10.1 for amplification as a 'good spot' for clear audio

Highlights

“To me amplify wins hands down. It smooths out the peaks of the audio. It's not so harsh compared to normalize.”
