Frequently Asked Questions

How can I make audio louder without distortion?

Use the normalization feature — it automatically raises the volume to the maximum possible level without clipping. Also watch the "Peak" indicator — if it's close to 0 dB, further amplification will cause distortion.

My MP3 is too quiet. How do I boost it?

Upload your file and move the gain slider to the right. Start with +3-6 dB and listen to the result. If the sound is still too quiet, try the "Maximum" normalization preset — it will raise the volume to the limit without distortion.

Can I boost volume of just part of the recording?

Yes! Go to the "Sections" tab and select the desired segment on the waveform. You can set a separate volume level for the selected section and apply changes without affecting the rest of the recording.

Is it safe to upload my files?

Completely safe. All processing happens locally in your browser — audio files are never sent to any server. Your recordings remain private.

When do I need normalization?

Normalization is useful when you need to match platform standards: YouTube requires -14 LUFS, Spotify -14 LUFS, podcasts typically -16 LUFS. This helps avoid jarring volume differences between tracks.
