Amplify quiet dialogue, soft video audio, and whisper recordings up to 500% with built-in limiter protection against crackle.
When a microphone is placed too far away, recordings can turn out frustratingly quiet. Simply cranking up computer volume also boosts background hiss and causes speakers to distort. Smart loudness boosting amplifies the signal while smoothing harsh peaks.
Worked example: Boost a quiet interview recording recorded in a large room
Input
An audio file where the speaker's voice is barely audible at normal volume.
Expected result
A boosted track where speech is clear and loud, without sudden clipping bursts.
The volume is lifted to a standard listening level while an automatic limiter prevents the loud parts from cracking the speakers.
Before you use the result
- Start with a moderate boost (150% to 200%) before trying maximum amplification.
- Listen through headphones to check that background room noise isn't overpowering the voice.
- Export and compare the volume against a standard song or podcast.
If the result is not what you expected
The boosted audio sounds fuzzy or distorted.
The boost level is set too high for that recording. Reduce the boost slider until speech sounds clean and natural.
Step-by-Step Walkthrough
Step 1

Step 2

Step 3
Test with the live player using the 'Boosted' and 'Original' comparison buttons, then click Save.
Pro Tip for Best Output Quality
Boosting audio beyond 400% on tracks with heavy background hum or fan noise will also amplify the background room noise.
