Master Your Music to Spotify's Exact Loudness Standard
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.

Pick your platform target
Select the streaming or distribution platform you are uploading to. The engine sets the correct LUFS, true peak ceiling, and dynamic profile.
Download and upload
Your master downloads as 24-bit WAV and 320 kbps MP3, normalized exactly to spec, ready to upload directly to your platform.
The solution
What MixMasterAI does for your Spotify release
Normalized to exactly -14 LUFS
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.
True peak limited to -1 dBTP
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.
Delivered as 24-bit WAV for lossless upload
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.
Spotify in depth
How Spotify's loudness normalization actually works
Spotify measures the integrated loudness of your whole track in LUFS, the loudness unit built into the ITU-R BS.1770 standard, then turns every song up or down so it plays back at a target of about -14 LUFS. If you master louder than -14, Spotify simply turns you down, so the extra loudness you fought for with a smashed limiter is thrown away and all you keep is the lost dynamics. If you master quieter, Spotify can turn you up, but only on its Normal setting, and it will not add loudness that risks clipping. The practical takeaway: master to -14 LUFS with peaks under -1 dBTP and your track plays back exactly as you made it, sitting level with every commercial song in the playlist.
What Spotify does to your file after upload
Spotify does not stream your WAV. It transcodes every upload to Ogg Vorbis at up to 320 kbps for premium listeners and lower bitrates for free and mobile users, and AAC in some contexts. That lossy encode is why the -1 dBTP true-peak ceiling matters: inter-sample peaks that read as 0 dB in your DAW can push past full scale after encoding and distort. Mastering with a true-peak limiter, not just a sample-peak limiter, keeps the encode clean. This is exactly what the mastering engine here does when you pick Spotify as the target.
FAQ
Questions about mastering for Spotify
What loudness does Spotify require?
Spotify normalizes all tracks to -14 LUFS integrated loudness during playback. If your master is louder than -14 LUFS, Spotify turns it down. If it is quieter, your track sounds weak compared to everything else. MixMasterAI hits -14 LUFS exactly.
What is true peak and why does it matter for Spotify?
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.
What format should I upload to Spotify?
Upload WAV or FLAC through your distributor for the best quality. Spotify encodes it to OGG for streaming. MixMasterAI delivers a 24-bit, 44.1 kHz WAV master ready for distributor upload.
