Frequently Asked Questions

How much can I boost the volume?

You can boost volume from 0dB (no change) up to 20dB (10x louder). For most applications, 6-10dB provides a noticeable increase without distortion.

Will boosting volume cause distortion?

Our volume booster includes anti-clipping protection that prevents distortion. However, if the original audio is already close to maximum volume, heavy boosting may cause some clipping. We recommend previewing before exporting.

What is the difference between volume boost and normalization?

Volume boost increases the overall volume by a fixed amount. Normalization analyzes the audio and increases volume to reach a target peak level. Use volume boost for quick amplification, or our Audio Normalizer for precise level matching.

Does volume boosting affect audio quality?

No. Our volume booster uses professional-grade gain control that maintains audio quality. The output is exported as high-quality WAV (16-bit PCM) with no quality loss.

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.

Can I use the output commercially?

Yes, all exports are royalty-free. You can use them for personal or commercial projects.
