Audio Mastering for Beginners: Where to Start
In short. Mastering is the last step before release: tonal balance, loudness to the platform standard and peak control. The working target for streaming is −14 LUFS integrated with True Peak no higher than −1 dBTP. Below is the whole path step by step: what to check going in, which numbers to set, and which mistakes most often spoil a finished track.
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 and YouTube
- −16 LUFS — Apple Music (Sound Check) and 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
- Export your mix as 24-bit WAV with no compression on the master bus
- Leave −3 dB of headroom (peaks no higher than −3 dBFS)
- 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 2b: choose the target loudness
| Platform | LUFS target | What happens if you go louder |
|---|---|---|
| Spotify | −14 | turned down by exactly the difference |
| YouTube | −14 | turned down |
| Apple Music | −16 | turned down |
| SoundCloud | −10 to −12 | no normalization — plays as uploaded |
| Club set / DJ | −8 to −9 | plays as is |
The key fact: normalization makes the loudness war pointless. A −10 LUFS master on Spotify won't be louder than the tracks around it — the platform lowers it to −14 and doesn't give back the dynamics lost to extra compression. The free streaming penalty checker shows how much each platform will turn your track down.
The processing order
The classic mastering chain, in exactly this order:
- Input correction — de-clipping and dynamics restoration if the source is over-compressed.
- EQ — tonal balance, sub-rumble cut.
- Multiband dynamics — per-band compression, even density.
- Saturation and stereo — harmonics up top, width where it belongs (the low end stays near mono).
- Loudness and limiter — reaching the target LUFS with a look-ahead limiter.
- True Peak control — the final ≤ −1 dBTP safety net.
In Magic Master this chain runs automatically: you pick the genre and platform, the service measures the input and sets the processing for it. You get a track passport with the actual LUFS, True Peak and dynamics, so the result can be checked rather than taken on trust. If you'd rather walk the chain by hand, the settings below are a safe starting point.
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
A good master is checked with numbers and ears:
- LUFS hits the target (±0.5 LU) — otherwise the platform steps in.
- True Peak ≤ −1 dBTP — otherwise clipping after re-encoding.
- The dynamics are alive: LRA well above 3 LU for music with drums; hits keep their attack.
- A/B against the original at the same loudness. Louder almost always seems "better" — compare honestly with levels matched. Magic Master has a snippet A/B built into the result player.
- Listen on different devices and compare against a reference track.
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. Mastering something already mastered
A second layer of limiting makes a track worse, not louder. If the source is already dense, it needs cleanup and dynamics restoration, not another master.
5. One master for every platform when the targets differ
SoundCloud suits −11 to −12 LUFS, streaming −14. For an important release, make two versions.
6. Mastering an album one track at a time
Each track pulled to the target independently means a quiet interlude gets inflated to single level. For multi-track releases there's album mode: the loudest track hits the target, the rest keep their intended levels.
7. No reference track
Always compare against a professional track in your genre. Better yet, let the
mastering match it for you: reference mastering shapes
your track's tonal balance after a reference you upload, while keeping your
own loudness.

Online or studio?
An engineer in a studio is irreplaceable for complex material: live recordings, unusual genres, artistic decisions. For the typical job — "bring the track to platform standard quickly and predictably" — automatic mastering does in minutes what takes a studio days. A sensible strategy many artists use: rough releases and singles online, the album of the year with an engineer.

Questions and answers
What is mastering, in simple terms?
The last stage of work on a track after mixing: evening out the tonal balance, bringing loudness to the platform standard (usually −14 LUFS) and controlling peaks (True Peak no higher than −1 dBTP), so the track sounds full and consistent on a phone, in headphones and in a car — and doesn't distort after streaming re-encoding.
Can I master a track online without software?
Yes. Upload a WAV, MP3 or FLAC in the browser, pick a genre and platform, and the service sets loudness to the target LUFS, holds peaks under −1 dBTP and processes dynamics per band. Guests get 3 free basic masters a month, a free account 1 per UTC day; no DAW or plugins needed.
What loudness should a streaming master have?
Spotify and YouTube normalize to −14 LUFS, Apple Music to −16 LUFS; SoundCloud doesn't normalize (−10 to −12 LUFS fits there). If you make one master for every platform, use −14 LUFS with True Peak at or below −1 dBTP — no platform will spoil it.
How is mastering different from mixing?
Mixing balances the tracks inside the project: levels, panning and effects on each instrument. Mastering works on the finished stereo file as a whole: tone, dynamics, loudness, peaks. Mastering won't rescue a bad mix, but it gives a good one density and competitive loudness.
Why not just push the limiter to zero?
First, platforms turn the track down to their norm anyway, so nothing is gained. Second, hard limiting eats dynamics: hits lose their attack and the mix gets flat and tiring. Third, peaks above −1 dBTP clip after the platform re-encodes to AAC or Ogg.
Which free plugins do I need to master myself?
A free set is enough to start in a DAW: TDR Nova (parametric EQ), OTT (multiband compressor — careful, it over-squeezes easily), Limiter No. 6 (limiter) and Youlean Loudness Meter (loudness). Re-check loudness and True Peak in the free Magic Master LUFS analyzer.
