Why your TikTok audio sounds too quiet
TikTok normalizes audio aggressively to roughly −8 LUFS (much louder than YouTube or Spotify), which means a quiet audio source going into a TikTok will get auto-boosted but with heavy compression artifacts. Pre-boost your audio to a comfortable level first, then add it to the video — the platform will leave it alone instead of mangling it.
When to use this TikTok booster
- Quiet voiceover recordings before adding them to TikTok videos
- Music samples to overlay on dance or transition clips
- Trending audio rips that play too quietly through TikTok's auto-mastering
Pro tips for TikTok
- TikTok rewards louder audio in the algorithm. Don't be afraid of +9 to +12 dB on quiet content.
- Mobile speakers vary wildly — test on at least two different devices before publishing.
Frequently asked questions
Why does my TikTok audio sound distorted?
TikTok's auto-mastering is aggressive — it tries to push everything to roughly −8 LUFS. Quiet source audio gets boosted with heavy compression that introduces pumping and distortion. Pre-boost your audio to about −10 LUFS before uploading and TikTok will leave it mostly alone.
What boost level works best for TikTok?
+9 dB is a solid starting point for most quiet recordings. TikTok's algorithm rewards loud audio in the For You feed, so don't be shy. Keep the limiter on to prevent distortion.
Can I boost a downloaded TikTok video's audio?
Yes — extract the audio, boost it, then remerge with the video. This page boosts the audio file. For full video processing on mobile, use the Loudify app.
