Frequently asked questions

What is LUFS and why does it matter for my mix?

LUFS (Loudness Units Full Scale) measures perceived loudness. Spotify normalizes to -14 LUFS, YouTube to -13 LUFS, Apple Music to -16 LUFS. If your mix is louder, platforms turn it down. If quieter, they boost it. Check your LUFS free at MixDiagnose.

How do I check if my mix is ready for mastering?

Upload your mix to MixDiagnose for free analysis. It checks LUFS, frequency balance, dynamic range, true peak, and mono compatibility. If all metrics are in the Ideal range, your mix is ready for mastering. 30 seconds, no signup required.

Why does my mix sound different on phone speakers?

Phone speakers are mono and lack bass. If your mix has phase issues or hard-panned elements, they cancel out in mono. Check mono compatibility free at MixDiagnose.

What is true peak and why does it matter?

True peak measures inter-sample peaks that regular meters miss. Even if your meter shows -0.1 dB, inter-sample peaks can exceed 0 dB and cause clipping on streaming platforms. Check true peak free at MixDiagnose.
