Spotify normalizes everything to -14 LUFS. If your master is louder, it gets turned down and loses punch. If it's quieter, it sounds weak next to every other track. MixMasterAI hits -14 LUFS precisely, every time. Free.
Technical requirements
MixMasterAI meets every one of these requirements automatically when you select Spotify as your platform target.
How it works
Drag and drop your mix. WAV, MP3, FLAC, M4A, and AIFF all accepted up to 50 MB.
Select the streaming or distribution platform you are uploading to. The engine sets the correct LUFS, true peak ceiling, and dynamic profile.
Your master downloads as 24-bit WAV and 320 kbps MP3, normalized exactly to spec, ready to upload directly to your platform.
The solution
MixMasterAI measures integrated loudness using the EBU R128 standard and normalizes your master to exactly -14 LUFS, the target Spotify uses for loudness normalization. Your track will play back at the intended volume in every playlist.
A brickwall limiter catches all true peaks above -1 dBTP before delivery. Spotify re-encodes uploads to OGG Vorbis, and unprotected peaks cause distortion in the encoded file. Every MixMasterAI master is safe.
Spotify accepts WAV, FLAC, and MP3. Uploading a 24-bit WAV through DistroKid, TuneCore, or CD Baby gives Spotify the highest quality source for encoding. MixMasterAI delivers 24-bit WAV as standard.
Also supports
Master for Spotify, Apple Music, YouTube, SoundCloud, TikTok, Amazon Music, and Tidal. Sixteen genre presets. Character presets for every style.

True peak measures inter-sample peaks that can exceed 0 dBFS after digital-to-analog conversion. Spotify re-encodes uploaded audio to OGG Vorbis, which can cause true peaks to clip. A -1 dBTP ceiling protects against this. MixMasterAI applies true peak limiting on every master.
