How to Master for TikTok & Reels

A -14 LUFS loudness meter beside a phone speaker, illustrating how to master for TikTok and Reels for short-form video

To master for TikTok and Reels, set your finished track to about -14 LUFS integrated with a -1 dBTP true-peak ceiling using the free volume normalizer — it measures your file, applies the exact gain offset, and caps peaks right in the browser. The whole pass takes about two minutes, and your audio never leaves your device: everything runs client-side, so there's no upload and no account. If you're starting from a raw mix rather than a finished bounce, glue and control it first with our audio mastering tool, then set loudness last.

Why short-form video is different

Streaming and short-form platforms both use loudness normalization, but they don't behave the same way, and that changes how you prepare a file.

First, a caveat that matters: neither TikTok nor Instagram publishes an official loudness spec. Every number here is measured and reported by engineers and creators testing uploads, not a documented target. The reported figures spread from roughly -10 to -14 LUFS depending on who's testing and when, so treat -14 LUFS as a safe consensus home base — aim there, and don't chase louder. (For the full picture of how loudness normalization works and what LUFS you should master to across platforms, we have primers.)

The key difference from Spotify: short-form platforms normalize in both directions. They turn loud uploads down and boost quiet uploads up toward the target. This has two consequences:

  • Uploading hotter than -14 buys you nothing. The platform pulls it back down, and all your extra limiting did was flatten the dynamics — you get a quieter feeling master, not a louder one.
  • Pre-normalizing a quiet file up before upload is genuinely worth doing. This is why weak, quiet exports sound buried: they get boosted, but the boost also raises the noise floor with them. Start from a clean, controlled file so the platform's upward gain lifts music, not hiss.

Contrast this with how you'd master for Spotify, which by default only turns loud tracks down and leaves quiet ones alone. On TikTok and Reels, a quiet upload is actively working against you.

Second: almost everyone hears your audio on a phone speaker. Dual phone speakers sit so close together that they collapse to effectively mono at the ear, and they can't reproduce deep bass — they're tuned for midrange. Midrange is the common denominator across phones, laptops, and Bluetooth speakers, so a mono-safe, midrange-forward, loudness-controlled master translates best.

Step by step: set loudness for TikTok and Reels

You'll work on a file you already have — an exported mix or bounce (MP3, WAV, FLAC, or M4A). There's no "paste a URL" step; this acts on your own audio.

  1. (Optional) Master the tone first. If your source is a raw mix rather than a finished master, run it through the audio mastering tool to glue the mix and apply gentle limiting. A normalizer alone can't master — it only sets loudness and peak. Do tone and dynamics first, loudness last.
  2. Open the free volume normalizer and drop your file in. Nothing uploads; the analysis happens on your device.
  3. Read the Before panel. It shows your file's measured integrated LUFS (what LUFS means) and its true peak in dBTP (true peak (dBTP)). This tells you which way you're moving — up if you're below -14, down if you're above it.
  4. Choose Loudness (LUFS) mode and pick the -14 target. There's no dedicated TikTok preset, because these platforms sit around -14 LUFS — the same as YouTube and Spotify. So click either the YouTube (-14) or Spotify (-14) preset button; both set the same target and work perfectly as your TikTok/Reels stand-in.
  5. Leave "Prevent clipping (cap true peak at -1 dBTP)" checked. This is your safety net — keep it on.
  6. Preview the after-LUFS. The After panel shows the resulting LUFS and true peak, plus the exact gain offset applied. Confirm it lands near -14 LUFS with peaks at or under -1 dBTP.
  7. Export and upload that file.

The same flow doubles as a video volume normalizer workflow: extract the audio, normalize it to -14 LUFS, and remux — a practical way to normalize audio for video before it hits the feed.

Why -1 dBTP, not 0

TikTok and Reels re-encode uploads to lossy AAC, and lossy encoding adds inter-sample peaks. A file sitting at -0.5 dBTP can come out of the encoder above 0 dBFS and clip on playback. A -1 dBTP ceiling absorbs that added overshoot. If you'd rather set the ceiling explicitly, switch to Peak mode and drag the target-peak slider to -1 dBTP.

Make it translate on a phone speaker

Loudness is only half the job. Because most plays happen on a near-mono, bass-shy phone speaker:

  • Check mono compatibility. Anything that vanishes or thins out when you collapse to mono — wide stereo effects, out-of-phase elements — will disappear on a phone. Keep the important stuff mono-safe.
  • Protect the midrange. Vocals, snare, and lead melody live here, and it's the one band every device reproduces. Don't let a scooped mix bury them.
  • Don't over-bass. Sub content the phone can't play still eats headroom and drives your limiter, squashing everything else to make room for bass nobody hears. Keep low end tidy.

Common mistakes

  • Chasing loudness past -14. Uploading at -8 doesn't make you louder — the platform turns it down, and you're left with over-limited, lifeless dynamics. This is the loudness war losing on a platform that fights back.
  • Uploading quiet vocal recordings raw. A quiet talk-over or acoustic take gets boosted up along with its room noise and hiss. Normalize it to -14 first, from a clean source, so the lift is clean.
  • Over-limiting until transients die. Smashed transients read as "flat" and "small" on phone speakers, exactly where it matters most. Preserve some punch.

Frequently asked questions

What LUFS should I master to for TikTok?

Aim for about -14 LUFS integrated with a -1 dBTP true-peak ceiling. TikTok doesn't publish an official loudness spec, but uploads are measured and reported to normalize to roughly -14 LUFS. Reported figures spread from -10 to -14, so treat -14 as a safe home base and don't push louder — the platform only pulls it back down.

Does mastering louder make my TikTok louder?

No. TikTok and Reels normalize in both directions, so a hot upload gets turned down to the target and a quiet one gets boosted up. Mastering past -14 LUFS only adds limiting that flattens your dynamics without any loudness payoff. Set -14 and stop.

Why does my song sound quiet on TikTok?

Usually the file was quiet and dynamically uncontrolled before upload. The platform boosts it up toward -14, but that upward gain also lifts the noise floor, so it sounds weak and hissy. Normalize to -14 LUFS from a clean, controlled master first so the platform lifts music, not noise.

Do I need different masters for TikTok vs Spotify?

Loudness-wise, no — both target about -14 LUFS, so the same -14 / -1 dBTP master serves both. The difference is behavior: Spotify by default only turns loud tracks down, while TikTok and Reels also boost quiet ones. Optimize your master for near-mono phone playback and it'll travel well across both.

Is -1 dBTP enough headroom?

Yes, for these platforms. TikTok and Reels re-encode to lossy AAC, which introduces inter-sample peaks that can push a -0.5 dBTP file over 0 and clip. A -1 dBTP ceiling absorbs that overshoot with margin to spare. Keep the "Prevent clipping" cap enabled so every export honors it automatically.
