Volume Booster: Audio Amp
Boost Volume & Bass Louder
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Volume Booster helps you make quiet videos and audio files louder straight on your iPhone or iPad. Choose media from Photos or Files, set how much extra volume you want, preview the result, then save an amplified copy to your library.
Use it when a video was recorded too softly, a lecture is hard to hear, a voice note needs more punch, or an audio file sounds quieter than the rest of your collection. The flow is simple: import, boost, compare, save.
Boost volume from the original level up to 1000 percent with Premium. Free users can boost up to 299 percent. The volume slider shows both percentage and dB, so you can pick a level that feels right instead of guessing. A live level meter shows what is happening as you adjust, and the built-in soft limiter helps keep boosted audio usable, not harsh clipping.
Volume Booster works with both videos and audio files. For videos, the app boosts the sound while keeping the original video track intact, so your footage stays as it was. For audio-only files, the app creates a boosted M4A file you can play, rename, keep, or share.
Want more low end? Premium also includes Bass Boost, a simple control that adds punch to low frequencies without changing your selected volume level. Great for music clips, workout videos, party edits, and anything that needs a fuller sound.
