Volume Booster
Amplify quiet audio or bring down overpowering tracks with precise dB control. Includes LUFS normalization presets for Spotify (−14 LUFS), YouTube (−14 LUFS), and Instagram Reels (−16 LUFS) so your content always hits platform loudness targets. Inconsistent volume is one of the most common reasons listeners bounce off a podcast or video early, and manually guessing a gain value rarely gets the loudness right. With LUFS-based normalization, the tool measures your file's actual perceived loudness and adjusts it to match the standard each platform expects, so your upload doesn't sound noticeably quieter or louder than everything else in a user's feed. A built-in limiter also helps prevent clipping distortion when boosting audio that's already close to peak level.

FAQ
How much can I boost the volume?+
You can boost as much as you want with the dB slider, but watch the waveform—too much will cause clipping (distortion)!
What is LUFS normalization?+
LUFS measures 'perceived' loudness. Streaming platforms have their own standards; normalizing to them ensures your audio sounds exactly as intended.
What is the LUFS standard for Spotify?+
Spotify normalizes to −14 LUFS. Just select our Spotify preset!
What about YouTube?+
YouTube also recommends −14 LUFS. Use our YouTube preset to match it perfectly.
Best volume for Instagram Reels?+
Reels recommends −16 LUFS. Our preset handles this in one click.
My audio sounds distorted after boosting.+
That's clipping. Lower the dB or use our LUFS presets for a clean, professional sound.
Can I lower the volume?+
Yes! Just move the dB slider into the negative values.
Does it work for both stereo and mono?+
Yes, both are supported equally.
Does it change my file format?+
No, it stays in whatever format you choose upon export.
