Advanced Mixing and Mastering

MIXING is turning many tracks into ONE balanced song. MASTERING is polishing that song for final release across Spotify, Apple Music, vinyl, and more. They are separate crafts. Together, they transform a rough session into a radio-ready master.

Pros follow a pattern:\n\n1. **Gain staging** — set each track around -18 dBFS so nothing clips\n2. **Mono balance** — pan everything center, balance volumes\n3. **EQ surgery** — cut problematic frequencies\n4. **Compression** — tame dynamics\n5. **Stereo imaging** — pan + widening\n6. **Effects** — reverb, delay, specialty\n7. **Automation** — rides and transitions\n8. **Bus processing** — drum bus, vocal bus\n9. **2-bus processing** — final polish before mastering\n\nSome engineers mix entirely in the box; others still track to outboard gear.

- **High-pass everything except kick/bass** — removes rumble\n- **Vocal presence** — boost 3-5 kHz\n- **Snare crack** — boost 5-8 kHz\n- **Kick thump** — boost 60-80 Hz\n- **Bass definition** — boost 700-1000 Hz\n- **Remove "boxiness"** — cut 200-400 Hz across mix\n- **Reduce harshness** — cut 2-4 kHz on aggressive sources\n\nEQ = equalization = boosting and cutting specific frequencies.

COMPRESSION reduces dynamic range. Set:\n\n- **Threshold** — when compression starts\n- **Ratio** — how much it compresses (2:1 gentle, 10:1 aggressive)\n- **Attack** — how fast it responds\n- **Release** — how fast it recovers\n- **Makeup gain** — restore volume\n\nUses: smooth vocals, control drums, glue mix together. Overcompression = lifeless. Balance is key.

Mastering is lighter-touch than mixing:\n\n- **EQ** — final tonal balance; broad strokes\n- **Multiband compression** — control different frequency ranges\n- **Limiting** — hit target loudness without clipping\n- **Stereo enhancement** — widen carefully\n- **Analog emulation** — saturation for warmth\n- **Dithering** — noise added when reducing bit depth\n\nMastering engineers use reference tracks — play your song next to a professional one to compare.

LUFS = Loudness Units relative to Full Scale. Target:\n\n- **Spotify** — -14 LUFS\n- **Apple Music** — -16 LUFS\n- **YouTube** — -14 LUFS\n- **Broadcast TV** — -23 LUFS (much quieter)\n- **CD/vinyl** — no strict limit\n\nPost-2012, streaming platforms NORMALIZE audio. Masters over the target get turned DOWN. So hitting -14 LUFS preserves your dynamic range better than slamming to -6 LUFS.

Every pro uses REFERENCES — professional songs in the same genre. Workflow:\n\n1. Pick 3-5 reference songs you admire\n2. Match genre and era\n3. Level-match (reference should sound SAME loudness as your mix)\n4. A/B toggle every few minutes while mixing\n5. Compare EQ balance, stereo width, punch\n\nWithout references, you drift into bad habits. With them, mixes stay anchored to industry standards.

- **Muddy mix** — too much 200-400 Hz in many tracks. Solution: high-pass mid-range sources\n- **Harsh** — 2-4 kHz buildup. Solution: cut on aggressive sources\n- **No punch** — kick and snare too compressed or buried. Solution: proper parallel compression + gain staging\n- **Narrow** — everything mono. Solution: careful stereo imaging on reverbs, pads\n- **Flat** — no automation. Solution: automate volume, filter, effects through sections\n- **Too loud** — hitting limiter too hard. Solution: target LUFS, not peak level
