Mastering for Beginners: Complete Guide
Mastering is the final step that transforms a good mix into a release-ready professional track. This guide covers the complete mastering chain: EQ, compression, stereo enhancement, limiting, and LUFS targets for streaming platforms (Spotify, Apple Music, YouTube).
🎯 What Is Mastering?
Mastering achieves 3 goals:
- Tonal balance: Fix frequency issues across the full spectrum
- Loudness: Match commercial release levels
- Consistency: Glue the mix together, prepare for distribution
Key rule: Mastering fixes small issues. If your mix is broken, go back and fix the mix (mastering can't save a bad mix).
🔗 Standard Mastering Chain
- Metering (LUFS meter)
- EQ (broad strokes)
- Compression (glue)
- Stereo Enhancement (optional)
- Saturation (optional warmth)
- Limiting (final loudness)
- Dithering (if exporting to 16-bit)
1️⃣ Mastering EQ: Subtle Corrections
Approach
- Broad Q: Wide bell curves (0.5-1.0 Q), not surgical cuts
- Small boosts/cuts: ±1-3dB maximum
- Linear phase: Avoid phase issues (FabFilter Pro-Q, iZotope Ozone)
Common Adjustments
- High-pass filter: Cut below 30Hz (remove rumble)
- Low-end: +1dB at 60-80Hz if thin
- Mud: -2dB at 300-500Hz if muddy
- Presence: +1-2dB at 3-5kHz if dull
- Air: +1dB at 10-12kHz for brightness
2️⃣ Mastering Compression: Glue
Settings
- Ratio: 1.5:1 to 3:1 (subtle!)
- Threshold: -3dB to -6dB
- Attack: Slow (30-50ms) to preserve transients
- Release: Auto or match song tempo
- Gain reduction: 1-3dB maximum (NOT 6-10dB like mixing!)
Plugin Recommendations
- SSL G-Master Buss Compressor: Classic glue
- FabFilter Pro-C 2: Transparent
- Slate Digital FG-Grey: Color
3️⃣ Stereo Enhancement: Width
When to Use
- If mix sounds narrow/mono
- Electronic music (techno, house)
How to Do It Safely
- M/S EQ: Boost sides at 8-12kHz (+1dB max)
- Stereo width plugin: 105-110% max (NOT 150%!)
- Check mono: Always fold to mono to ensure compatibility
Warning: Too much width = phase issues + weak on clubs/phones.
4️⃣ Saturation: Warmth & Glue
Why Add Saturation
- Adds analog warmth
- Generates harmonics (perceived loudness)
- Glues mix together
Plugins
- Soundtoys Decapitator: Aggressive color
- Slate Digital VTM: Tape emulation
- iZotope Ozone Exciter: Subtle harmonics
Settings: Drive low (10-20%), mix at 20-30%.
5️⃣ Limiting: Final Loudness
What Is a Limiter?
A limiter is a brick-wall compressor (∞:1 ratio) that prevents peaks from exceeding 0dBFS.
Settings
- Ceiling: -0.3dBTP (true peak) for streaming
- Input gain: Increase until target LUFS reached
- Release: Fast (auto) to avoid pumping
Best Limiters
- FabFilter Pro-L 2: Transparent, industry standard
- iZotope Ozone Maximizer: Intelligent limiting
- Waves L2: Classic aggressive sound
📊 LUFS Targets for Streaming
What Is LUFS?
LUFS (Loudness Units Full Scale) = perceptual loudness standard used by streaming platforms.
Target LUFS by Platform
| Platform | Target LUFS | What Happens If Too Loud |
|---|---|---|
| Spotify | -14 LUFS | Turned down (normalization) |
| Apple Music | -16 LUFS | Turned down |
| YouTube | -13 to -15 LUFS | Turned down |
| Tidal | -14 LUFS | Turned down |
| SoundCloud | -8 to -13 LUFS | No normalization (louder wins) |
| CD / Club | -8 to -10 LUFS | Loud = better impact |
Recommendations
- Streaming release: -14 LUFS integrated (Spotify standard)
- Club banger: -8 to -10 LUFS (more punch)
- Dynamic genres (jazz, classical): -16 to -18 LUFS (preserve dynamics)
How to Check LUFS
- Youlean Loudness Meter (FREE)
- iZotope Insight 2
- Waves WLM Plus
6️⃣ Dithering: Final Export
What Is Dithering?
Dithering adds noise to reduce digital distortion when converting from 24-bit to 16-bit (CD quality).
When to Dither
- YES: Exporting to 16-bit WAV (CD, streaming upload)
- NO: Staying in 24-bit (archival master)
Settings
- Type: TPDF or POW-r 2
- Noise shaping: Moderate (pushes noise above hearing range)
Important: Dither ONCE at the very end. Never dither twice.
✅ Complete Mastering Workflow
- Import mix: Ensure -6dB headroom (NOT hitting 0dBFS)
- Add LUFS meter: Monitor loudness
- EQ: Broad corrections (±1-2dB)
- Compress: 1-3dB gain reduction for glue
- Saturate (optional): 10-20% drive, 30% mix
- Limit: Push to target LUFS (-14 for streaming)
- Check: Mono, different speakers, reference track
- Export: 24-bit WAV (master), 16-bit with dither (distribution)
❌ Common Mistakes to Avoid
- ❌ Over-limiting: -6 LUFS = lifeless, distorted
- ❌ Too much compression: Should be 1-3dB, not 10dB
- ❌ Extreme stereo width: Phase issues in mono
- ❌ No headroom in mix: Start with -6dB master level
- ❌ Fixing mix problems: Mastering can't fix bad balances
🎯 Key Takeaways
- -14 LUFS = streaming standard (Spotify, Apple Music)
- Less is more: Subtle adjustments (1-3dB)
- Limiting last: EQ/compression BEFORE limiter
- Check mono: Always fold to mono to test compatibility
- Reference tracks: A/B with pro masters in your genre
- Dither once: Only when exporting to 16-bit
Remember: Mastering enhances a great mix. Fix problems in mixing, polish in mastering.
