How to Master a Song for TikTok (So It Hits on Phone Speakers)

Updated July 2026 · by Loopin

TikTok lives on tiny mono phone speakers and a three-second attention window. A master that sounds great in your headphones can disappear in the feed if it’s too quiet, too wide or too low-end heavy. Here’s how to master a song so the hook actually lands on TikTok — and how to do it free in a couple of minutes.

Does TikTok have a loudness target?

TikTok doesn’t publish an official number, but like every modern platform it normalizes playback loudness — it turns loud uploads down and quiet ones up toward a consistent level. Chasing a brick-wall “as loud as possible” master doesn’t win; it just gets turned down, and you keep the distortion.

The safe, platform-agnostic target that travels well to TikTok, Reels and Shorts is around −14 LUFS integrated with a −1 dBTP true-peak ceiling. Master to that and your track sits at a competitive level everywhere without pumping or clipping.

Integrated loudness: ~−14 LUFS (a touch louder, −12 to −13, is fine for hard-hitting genres)
True peak: −1 dBTP, so lossy encoding doesn’t push it into clipping
Don’t master to −7 LUFS hoping to be “loud” — it gets normalized down anyway

Why mastering for TikTok is different

The playback reality is brutal: most people hear your song through a single mono phone speaker with almost no bass, often while scrolling. Two things follow from that. First, anything you hid in the stereo sides (wide reverb, panned doubles) can vanish or smear when the phone sums to mono. Second, sub-bass you feel on headphones simply isn’t reproduced, so your energy has to live in the midrange.

The other factor is the hook. TikTok clips start mid-song and the first few seconds decide everything. A master that’s clear, present and loud from the first beat beats one that needs a big system to sound good.

Step by step: master a song for TikTok

Assuming your mix is done and bounced with headroom (peaks around −6 dB, no limiter on the mix bus), the master itself is quick:

Bounce your final mix as a WAV (not MP3) so mastering has full quality to work with.
Open Loopin’s free online mastering and drop the file in.
Pick a feel that suits the track — Punchy or Club for beats and pop, Warm for acoustic and R&B.
A/B Original vs Mastered, and check the mono fold-down — the hook should stay clear, not hollow.
Confirm it lands near −14 LUFS with true peak at −1 dBTP, then download the mastered WAV.
Upload that WAV to TikTok (or your video editor) rather than a low-bitrate MP3.

Make it translate on phone speakers

Because the phone speaker is mono and thin, a TikTok-ready master should be checked for the things that fall apart there:

Mono check: collapse to mono and make sure the vocal and hook don’t drop in level or go hollow (a sign of phase issues in the mix).
Midrange presence: the 1–4 kHz range carries on small speakers — if the vocal is buried there, it’ll be buried on TikTok.
Controlled low end: keep the sub tidy and mostly mono; a boomy, wide low end wastes headroom you could spend on loudness that phones actually reproduce.
Consistent level: if your verse is quiet and the drop is huge, normalization and the tiny speaker will flatten it — a gentle master evens that out.

Common mistakes

Mastering too loud. Squashing to −7 LUFS just trades dynamics for distortion that survives the turn-down.
Uploading an MP3 of an MP3. Master from WAV and upload WAV; let TikTok do the final compression once.
Mixing wide, forgetting mono. Big stereo tricks that never get mono-checked can gut your hook on a phone.
Fixing the mix in the master. If the vocal is too quiet or the low end is muddy, go back to the mix — mastering polishes the whole, it can’t rebalance parts.

Do it free, in the browser

You don’t need a paid mastering service or a plugin chain to get a TikTok-ready track. Loopin’s online mastering runs a real chain — corrective EQ, multiband compression, saturation, M/S stereo with the bass kept mono, loudness targeting to about −14 LUFS and a −1 dBTP true-peak limiter — entirely in your browser. Nothing is uploaded, it’s free, and it takes a couple of minutes.

Master the WAV, do a quick mono check, and your hook is ready to compete in the feed.

Frequently asked questions

What LUFS should a TikTok song be?

Aim for around −14 LUFS integrated with a true peak of −1 dBTP. TikTok normalizes playback, so mastering much louder than that just gets turned back down while keeping any distortion you added.

Do I need to master before uploading to TikTok?

It helps a lot. TikTok plays on mono phone speakers, so a master that sets a competitive loudness, controls the low end and stays clear in mono makes your hook cut through far better than a raw mix.

Should I upload a WAV or MP3 to TikTok?

Master from a WAV and upload the WAV (or the highest-quality file your editor accepts). Let TikTok apply its own compression once, rather than stacking MP3-on-MP3 quality loss.

Why does my song sound quiet or thin on TikTok?

Usually two reasons: it was mastered too quiet (or too loud, then normalized down), or its energy lives in sub-bass and stereo width that a mono phone speaker can’t reproduce. Master to −14 LUFS and keep the midrange present.

Can I master for TikTok for free?

Yes. Loopin’s online mastering is free, needs no account and runs in your browser — upload your mix, pick a feel, check the mono fold-down and download a mastered WAV.
