Is Magic Master free?

Yes, with limits: guests get 3 free masters per month and registered accounts get 1 per day. Full PRO features are pay-as-you-go tokens with no subscription.

What is AI mastering?

Automatic audio mastering in your browser: it sets loudness to platform LUFS targets, controls True Peak (ITU-R BS.1770-5) and applies multiband dynamics in about 20 seconds.

Can it clean AI artifacts from Suno or Udio tracks?

Yes. A dedicated module removes AI fingerprints and separation artifacts from AI-generated music before mastering.

What formats and loudness targets are supported?

16 platform LUFS targets (Spotify, Apple Music, YouTube and more) with export to WAV, MP3 and FLAC.

What's new in Magic Master 3.8

Release 3.6 — more reliable and faster on long tracks: fixed a false "Mastering error" on long tracks (progress stream ceiling 600s→20min + heartbeat) and parallel per-channel spectral processing (byte-identical, up to ~1.3× faster on cleanup/denoise):

AI-trace cleanup v3 — we restore the "air" and strip the metallic sheen: cleaner, more alive result
Cleanup visualization — save and share a before/after image to show the difference
One-click cleanup — a run button right in the block, no scrolling to settings
AI picks the genre — it reads the track's character instead of a "mute" Standard
Bring friends — referral program: +3 tokens for you, +2 for a friend, and more for partners

ℹ️ What mastering does — and what it can't

Does: shapes the overall tone, loudness (LUFS) and peaks of the whole track — so the mix sounds tight and platform-ready.

Can't: rebalance individual instruments or vocals, "bring the voice up", add parts — that's mixing. Need that? Adjust the mix in your DAW and upload a fresh premaster.

What is True Peak and why it matters for streaming

True Peak (dBTP) accounts for inter-sample peaks after AAC/Opus. Sample-peak can be misleading — a track looks clean but clips once uploaded to Spotify. Magic Master measures True Peak with oversampling and keeps −1 dBTP headroom.

LRA — your track's dynamic range

LRA shows the loudness spread in LU: 0–5 — tight, 5–10 — balanced, 10–15 — dynamic, 15+ — very dynamic (often classical/jazz).

How to pick a genre (23 presets)

Stream — universal −14 LUFS
EDM / House / Trap — dense, loud club sound
Pop / K-Pop / Afrobeats — commercial balance
Rock / Metal — bite and density
Hip-Hop / R&B — powerful lows and warm mids
Classical / Jazz / Lo-fi — dynamics and reverb
Podcast / Dry Vocal / Country — voice and naturalness

How to pick a platform (LUFS targets)

Spotify and YouTube — around −14 LUFS, Apple Music — −16, Club — −9, Broadcast — −23. Pick a platform in the settings and the target LUFS is filled in automatically.

The Streaming-Ready badge — what it means

The green check appears when LUFS lands within ±2 LU of the platform target and True Peak ≤ −1 dBTP. It's not a distributor moderation guarantee, but a good 'ready to release' signal.
