FAQ
Frequently Asked Questions
How does Volume Booster make audio louder without clipping?
When boosting volume beyond 0 dBFS, traditional linear gains cause harsh digital clipping. Our volume booster passes audio through an analog-modeled soft-saturation curve, smoothly rounding peaks while preserving transient clarity.
How much volume boost should I apply?
For quiet voice notes and podcast tracks, +6 dB to +9 dB is usually ideal. For very quiet microphone recordings, you can boost up to +15 dB.
Is my audio private?
Yes. All gain calculations run entirely in your web browser. Nothing is uploaded to any server.
