After analyzing 1,000+ mixes with AI, clear patterns emerged between amateur and professional mixes.
73% of amateur mixes have 3+ dB buildup in the 250-500 Hz range. Only 12% of pro mixes have this issue.
Amateurs mix at -8 to -10 LUFS. Pros mix at -14 to -18 LUFS. When you mix quiet, you hear dynamics. When you mix loud through a limiter, everything sounds "finished" — but it's the limiter doing the work.
Amateur crest factor: 5-7 dB. Pro crest factor: 10-14 dB. Amateurs over-compress because they put compressors on every channel AND the master bus AND a limiter.
29% of amateur mixes have stereo correlation below 0 — elements disappear in mono. Pro mixes? Zero.
44% of amateur mixes boost highs above 10 kHz with "air" plugins. Pros rarely boost highs — they cut harshness at 3-5 kHz instead.
Amateur mixes try to add things — boost frequencies, add compression, add limiting. Pro mixes try to remove things — cut mud, remove unnecessary compression, eliminate phase issues. Mixing is subtractive.
