Audio Booster: Make Your Video Voice Stand Out

Fix low-volume phone recordings and make your video audio crisp and loud using our proprietary browser-based core.

Poor audio can ruin a great video. If you recorded a video on your phone and the voice is too quiet, an audio booster can save it. Instead of just cranking the volume and adding noise, a smart booster normalizes the audio to make it louder and clearer.

Our browser-based core allows you to boost your video's volume locally without needing a professional audio suite.

Why boost audio in the browser?

  • Privacy: Your original recordings stay on your device. No cloud uploads for private voice notes or interviews.
  • Fast Fix: Quickly fix quiet clips before uploading them to social media.
  • Hardware Optimized: Our proprietary processing core uses your computer's power for clean, artifact-free gain.

When to use an audio booster

  • Fixing quiet voiceovers in phone recordings.
  • Making background interviews audible in noisy environments.
  • Prepping videos for platforms with loud default playback (like TikTok).
  • Ensuring consistent volume across a series of clips.

Fast workflow

  1. Upload your video file.
  2. Adjust the boost level (e.g., +6dB or 200%).
  3. Preview the new audio levels to ensure no clipping occurs.
  4. Download your enhanced video with loud, clear sound.

Pro tips

  • Avoid Clipping: If the audio gets distorted (crackling), lower the boost slightly.
  • Normalization: Sometimes "Normalizing" to 100% is better than a flat percentage boost.
  • Check Different Speakers: Test the boosted audio on both headphones and your phone speaker.

Checklist

  • Source video has quiet but clear audio.
  • Boost level makes the voice audible without distortion.
  • Audio and video remain perfectly in sync.
  • Final output is verified on multiple playback devices.

FAQ

Does this add background noise? Boosting volume also boosts the noise floor. Our proprietary core attempts to minimize this effect, but it's best to start with clean (even if quiet) source audio.

Can I boost just the voice? Our current tool boosts the entire audio track. For vocal-only isolation, stay tuned for our upcoming AI tools.

Is it safe for long videos? Yes, our browser-based core can process full-length videos efficiently.
