Tech House Daily - MIXING SCIENCE Friday, September 12, 2025. Today we break down the technical craft that separates amateur bedroom producers from professional DJs and producers. Starting with frequency separation mastery — the foundation of professional tech house mixing. The kick drum must own 60–80 Hz exclusively, while the bassline sits in the 80–120 Hz pocket. Use surgical high-pass filtering on everything except kick and bass, starting ~100 Hz and adjusting by ear to avoid low-end mud. EQ strategy follows the surgical-before-musical approach. First, remove problems (cut 200–400 Hz mud, tame 2–4 kHz harshness), then enhance. Prioritize midrange clarity (800 Hz–2 kHz) so vocals, leads, and claps cut without fighting. Compression intelligence serves groove. Parallel compression on drum groups for punch while preserving transients: smash the send, blend back to taste. Use multiband lightly below 1 kHz for cohesion without choking the groove. Stereo imaging creates a wide, immersive stage: keep kick, snare, bass mono-center; spread hats, tops, and atmos with tasteful width. The key is contrast — wide feels wider against a focused center. Modern sidechain is felt, not heard. Subtle kick-triggered ducking (fast attack, medium release, ~2–3 dB GR) to carve micro-pocket without obvious pumping. Use ghost-kicks in breakdowns to keep motion alive. Harmonic saturation adds character: gentle tape on the mix bus, tube on bass, tasteful grit on percussion. Aim for vibe, not distortion. System translation separates pros from amateurs: reference on club PA emulations, monitors, earbuds, and phones. Match spectral balance to reference tracks; check mono compatibility for sub-region solidity. Master the science, then let your taste drive the final 10%.
