Mixing and Mastering Explained
The difference between mixing and mastering, what they cost, and when to hire out.
Mixing vs Mastering
Mixing and mastering sound similar but do fundamentally different things. Mixing is blending multiple tracks into a stereo pair—adjusting levels, panning, EQ, reverb, and effects to create clarity and balance. Mastering is the final step: taking that stereo mix and optimizing it for distribution across all playback systems (headphones, speakers, cars, streams).
Think of it this way: mixing is building the house; mastering is inspecting it and ensuring it meets code before the buyer moves in.
What Engineers Do
A mixing engineer receives your raw stems (vocals, drums, bass, instruments) and:
- Balances levels so each element sits right
- Fixes timing and tuning issues
- Adds compression, EQ, reverb to glue the track
- Creates width, depth, and movement with effects
A mastering engineer receives your stereo mix and:
- Checks it on multiple playback systems to catch problems
- Applies gentle EQ and compression to optimize frequency balance
- Prevents clipping and ensures loudness standards (LUFS)
- Creates multiple versions for different platforms (Spotify, Apple Music, YouTube)
DIY vs Hiring Out
You can mix and master yourself if you have a treated room, good monitors, and years of practice. Most artists don't—your ears get tired, you lose objectivity, and untrained speakers hide problems.
Mixing DIY: Harder. Requires critical listening skills and a balanced monitoring environment.
Mastering DIY: Even harder. A mastering engineer hears on professional gear and knows loudness targets for each platform.
For artists starting out, hiring a mixing engineer and doing a quick self-master is a middle ground. Record and edit yourself, hire mixing, master in LANDR or eMastered.
Typical Costs
Mixing:
- Budget ($200–500): emerging producers, often faster turnaround
- Mid-range ($500–1,500): experienced engineers, 2–3 revisions included
- High-end ($1,500–5,000+): top producers, unlimited revisions, on major releases
Mastering:
- LANDR or eMastered (AI-based): $25–100
- Independent mastering engineer: $50–300 per song
- Top mastering houses: $500–1,000+
For a 10-song album: expect $2,000–3,000 mixing + $500–1,500 mastering total at mid-range rates.
Online Services
LANDR and eMastered use AI to deliver instant, affordable mastering. Results are good enough for demo and streaming release, though they lack the human touch of a professional mastering suite.
Human alternatives: Fiverr, Topflight, etc. offer mixing and mastering at low rates—quality varies.
The safe bet: hire a professional mixing engineer for one song as a reference, then decide whether DIY tools work for your sound and ears.
