Frequently Asked Questions
How does peak limiting prevent distortion when boosting volume?
Our volume booster employs dynamic range compression and soft limiting, preventing boosted acoustic waves from flatlining against the 0dB digital ceiling and causing harsh clicks.
By how much can I boost quiet audio?
You can amplify sound levels from +1dB up to +20dB (a 300% increase in acoustic power) to bring quiet whispering or distant microphones up to standard listening levels.
Can I also use this tool to lower the volume of overly loud audio?
Yes. The gain slider can attenuate audio downward to prevent deafening playback or match quieter tracks.
