Audio Mastering for Beginners: Where to Start

Audio Mastering for Beginners: Where to Start

What is mastering?

Mastering is the final stage of audio processing before release. Its goal is to make your track sound good on any device: headphones, speakers, a phone, a car stereo.

Mastering vs. Mixing

Stage	What it does	When
Mixing	Balancing instruments, panning, effects	After recording all the tracks
Mastering	Loudness, EQ, compression, limiting	Final stage before release

Key concepts

LUFS (Loudness Units Full Scale)

LUFS is the loudness unit streaming platforms use to measure your track.

• −14 LUFS — the standard for Spotify, YouTube, Apple Music
• −16 LUFS — the standard for podcasts
• −9 LUFS — loud (EDM, club music)
• −18 LUFS — quiet (jazz, classical)

True Peak (dBTP)

True Peak is the maximum signal level, accounting for inter-sample peaks.

• ≤ −1.0 dBTP — safe for streaming
• > 0 dBTP — clipping (distortion)

Compression

A compressor narrows the dynamic range: it makes quiet parts louder and loud parts quieter.

• Ratio — how much compression is applied (2:1 = gentle, 4:1 = hard)
• Threshold — the level where compression kicks in
• Attack — how fast the compressor reacts

Equalizer (EQ)

EQ adjusts the balance of frequencies:
- Bass (20–200 Hz) — the foundation, kick drum
- Mids (200–5000 Hz) — vocals, guitars
- Highs (5000–20000 Hz) — air, presence

Step-by-step mastering process

Step 1: preparation

1. Export your mix as 24-bit WAV with no compression on the master bus
2. Leave −3 dB of headroom (peaks no higher than −3 dBFS)
3. Check for phase issues (L/R correlation > 0.5)

Step 2: analysis

Measure the current parameters:
- LUFS — current loudness
- True Peak — presence of clipping
- Spectrum — frequency balance

Step 3: EQ correction

• Cut rumble (high-pass filter, 20–40 Hz)
• Give presence a slight lift (2–4 kHz, +0.5 dB)
• If needed, clean up "mud" (200–400 Hz, −0.5 dB)

Step 4: compression

For beginners:
- Ratio 2:1 (gentle)
- Threshold −18 dB
- Attack 10 ms
- Release 100 ms

Step 5: limiting

• Ceiling −1.0 dBTP (for streaming)
• Threshold tuned to hit your target LUFS

Step 6: verification

• Listen on different devices
• Compare against a reference track
• Check LUFS and True Peak

Common beginner mistakes

1. Mastering too loud

❌ −6 LUFS → Spotify turns it down → lost dynamics
✅ −14 LUFS → optimal for streaming

2. Over-compressing

❌ Ratio 8:1, Threshold −30 dB → "cardboard" sound
✅ Ratio 2:1, Threshold −18 dB → transparent processing

3. Ignoring True Peak

❌ Peak at 0 dBFS → inter-sample peaks exceed 0 → clipping
✅ Peak at −1.0 dBTP → safe

4. No reference track

Always compare against a professional track in your genre.
