Fix bass-heavy track normalization for TikTok
If your audio sounds wrong on TikTok, you are not alone. TikTok automatically applies loudness normalization to every track it streams — targeting -14 LUFS integrated loudness. When your uploaded audio sits too far from that target, the platform's gain stage kicks in and the result can sound distorted, lifeless, or simply too different from what you intended. The solution is to normalize your audio before you upload, so TikTok has nothing to correct. LoudFix does this in your browser in under a minute, with no account required and no files leaving your device.
Why Does TikTok Change My Audio?
TikTok uses the ITU-R BS.1770-4 loudness standard to measure integrated LUFS across your entire track and applies a gain adjustment so the result matches -14 LUFS. This process is automatic and invisible — you have no way to disable it from the upload side. If your track is louder than -14 LUFS, TikTok turns it down. If your track is quieter, some platforms (including those that normalize "both ways") may turn it up, which amplifies any noise floor or compression artifacts in your original. True peak is also limited to -1 dBTP: inter-sample peaks that exceed this threshold get hard-limited, introducing subtle but audible distortion on transient-heavy material like snare hits and acoustic guitars.
How LoudFix Fixes the Problem
LoudFix measures your file's integrated LUFS, short-term loudness, momentary loudness, true peak, and loudness range (LRA) against TikTok's exact specification (-14 LUFS, -1 dBTP). It then applies a single linear gain adjustment — no compression, no limiting, no EQ — to bring the file into compliance. The result is mathematically identical to your original recording, just at the correct volume. Because the adjustment is transparent, what TikTok streams is your mix as you intended it, with no platform-side processing left to apply. The recommended delivery format for TikTok is AAC 256 kbps, which LoudFix can export directly.
How to Fix bass-heavy track normalization for TikTok (3 steps)
-
Step 1
Drop your audio file into LoudFix
Drag and drop your WAV, FLAC, MP3, or AAC file onto the LoudFix tool above. The analyzer reads your file locally — nothing is uploaded to any server.
-
Step 2
Select the TikTok preset
LoudFix pre-selects the TikTok preset automatically on this page. It targets -14 LUFS integrated and -1 dBTP true peak — the exact spec TikTok enforces.
-
Step 3
Download the normalized file
Click Convert and download. Your normalized audio is ready to upload to TikTok. The file will pass TikTok's loudness normalization without any platform-side adjustments.

Frequently Asked Questions
- Will normalizing to -14 LUFS make my music sound quieter?
- Compared to a heavily limited master targeting −6 LUFS, yes — it will play back at a lower volume on conventional speakers. But it will sound exactly the same as every other track on TikTok, and listeners will not reach for the volume knob mid-playlist. Listeners actually prefer consistent loudness over loud-but-distorted tracks.
- Does TikTok normalize both up and down, or only down?
- TikTok's normalization applies a gain adjustment to reach -14 LUFS. Tracks already at or below -14 LUFS may or may not be turned up depending on the platform's current policy. The safest strategy is to deliver at exactly -14 LUFS so the platform has nothing to adjust in either direction.
- What is true peak and why does it matter for TikTok?
- True peak measures inter-sample peaks — digital samples that, when converted to analogue, overshoot the encoded value. TikTok limits true peak to -1 dBTP. Exceeding this causes hard clipping at the D/A stage, audible as a crispy distortion on loud transients. LoudFix measures and controls true peak automatically.
- What audio format should I upload to TikTok?
- The recommended delivery format for TikTok is AAC 256 kbps. Start from the highest-quality source you have (ideally a 24-bit WAV or FLAC mix before mastering) and export at the delivery spec. Avoid re-encoding a lossy MP3 — every encode cycle adds artifacts.
- Is LoudFix free to use?
- Yes. LoudFix is free, browser-based, and requires no account or installation. Your audio is processed entirely on your device — no files are sent to any server.
