How to boost vocals

  1. Choose one audio file up to 64 MB. Start with WAV or MP3 for broad browser support.
  2. Start with Quick Boost and a small Vocal boost. For stereo recordings, try Spectral Focus and compare.
  3. Select Boost vocals, listen to the original and result, then choose Download WAV. Changing settings requires another boost.

Tips for clearer vocals

Start around +3 to +6 dB and listen at a comfortable volume. Strong boosts can emphasize harshness or background noise.

Lower Center focus if a voice sits to one side. Spectral Focus works best as an experiment with centered voices in stereo; it can also lift drums and other centered sounds.

When should you use Vocal Booster?

Try it when spoken words or singing feel recessed in a recording. It can add presence to interviews, voice clips, and music without rebuilding the mix.

It does not isolate vocals, remove noise, or recover words completely buried by music. Compare before and after before keeping the result.

Private local processing

Your audio stays on your device. Process one file at a time and keep this page open until it finishes. Longer recordings need more time and memory, especially on phones.

FAQ

No. Your original audio and finished WAV stay on your device. Nothing is uploaded for processing.
Start with WAV or MP3. Other formats work when your browser can open them. The download is always a 16-bit WAV at 48 kHz, with the original mono or stereo channels.
No. Both methods bring vocals forward without separating them from the music. Centered instruments and some noise may also become louder.
Start with Quick Boost for mono or stereo audio. Spectral Focus is experimental and needs stereo audio; compare the result because it may also boost centered instruments.
Choose one file up to 64 MB and 30 minutes. Long stereo recordings can reach the device-memory limit much sooner. If processing fails, try a shorter recording.
Peak protection lowers the whole result evenly when the boost needs more headroom. It avoids sample clipping while keeping the new balance, but does not guarantee true-peak protection.
Your browser may not play every audio format. Try WAV or MP3 for the original. If a finished preview does not play, you can still download the WAV and listen in your usual player.
