Why Use a Volume Booster?
We've all been there: you record an important lecture, a voice memo, or download a song, but the audio is so quiet that you can barely hear it even with your device's volume at 100%.
A Volume Booster (Audio Amplifier) digitally increases the gain of the audio file, permanently making it louder so you don't have to strain your ears.
The Dangers of Clipping
When boosting volume, the biggest risk is clipping (distortion). If you increase the gain too much, the audio waves hit the digital ceiling, causing a harsh, crackling sound.
To avoid this, our tool allows you to gradually increase the volume (e.g., +3dB, +6dB) and preview the result.
