Audio Volume Booster increases the loudness of audio files that are too quiet. Whether a voice recording was made too far from the microphone or a downloaded file plays at low volume, this tool amplifies the audio to a comfortable listening level without distortion.
- 1Upload the quiet audio file.
- 2Set the amplification level using the volume slider (in decibels).
- 3Preview the boosted audio to confirm it is not distorted.
- 4Click "Boost Volume" and download the louder file.
- →Boosting quiet voice recordings made on a phone or basic microphone.
- →Increasing volume of downloaded audio that plays too softly.
- →Amplifying audio before merging it with louder background music.
- →Preparing audio for hearing-impaired listeners who need higher volume.
- →Normalising quiet segments of a longer recording.
Will boosting cause distortion?
Excessive amplification beyond the audio's headroom causes clipping/distortion. Start with small increases and preview before downloading.
What is a decibel (dB)?
Decibels measure sound level. +6 dB roughly doubles the perceived loudness. +3 dB is a noticeable increase.
What is the maximum boost available?
Up to +20 dB of amplification is available. Use the preview to check for clipping before applying.
Is it better to use the normaliser instead?
For consistent results, use Audio Normalizer which automatically sets the optimal volume level. Volume Booster gives manual control.
