Mastering Checklist: The 12 Steps

1. Listen on cheap speakers – Play your mix on the worst speaker you own; if vocals, kick, and snare still come through, you’re on the right track.
2. Check the mono compatibility – Switch to mono and make sure nothing disappears; a vanished guitar or synth signals phase issues to fix.
3. Look at the peak levels – Ensure your loudest peaks stay under -1 dBTP to leave headroom for the limiter later.
4. Sweep the low end – Apply a high‑pass filter on non‑bass instruments to clear mud below 30 Hz, tightening the kick and bass.
5. Balance the stereo width – Pan elements gently; keep bass, kick, and vocals centered while widening stereo to enhance, not distract.
6. Fix any harsh frequencies – Sweep a narrow boost around 2‑5 kHz and cut if it hurts your ears; a small reduction goes a long way.
7. Add subtle saturation – A touch of tape or tube warmth can glue the mix together without sounding distorted.
8. Check the loudness – Use a LUFS meter and target around -14 LUFS for streaming platforms; adjust gain before limiting.
9. Apply gentle compression – If the mix feels uneven, a light bus compressor with a low ratio (1.5:1) smooths things out.
10. Set the final limiter – Place a limiter on the master bus, set the ceiling to -0.3 dBTP, and push gain until you hit your LUFS target; watch for pumping.
11. Listen on multiple devices – Test on headphones, car speakers, phone earbuds, and a home stereo; take notes on what changes.
12. Add fades and export – Fade in the first 10 ms and fade out the last 50 ms to avoid clicks, then export as a 24‑bit WAV (or preferred format) and do a final listen.

Each step is a single action; checking them in order prevents overwhelm and catches details you’d otherwise miss.

Running through this mastering checklist turns that vague “something’s off” feeling into a confident workflow—mix, check, export, and know your track will sound great everywhere.
