Frequently Asked Questions
How does the bass booster work?
Our bass booster uses a low-pass filter centered at 200Hz to enhance frequencies below 200Hz. This adds depth and warmth to your audio without affecting higher frequencies.
Will boosting bass cause distortion?
Moderate bass boost (3-6dB) typically won't cause distortion. However, maximum boost (12dB) may cause clipping in some audio. If you hear distortion, reduce the boost amount or use our Audio Normalizer after boosting.
What is the best bass boost setting for music?
For most music, 3-6dB provides a noticeable enhancement without overwhelming the mix. For bass-heavy genres like hip-hop or EDM, 6-9dB works well. Use 12dB only for testing or extreme enhancement.
Does bass boosting affect audio quality?
No. Our bass booster uses professional-grade digital filters that maintain 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.
