How It Works

Human ears are not flat. We hear 2-4 kHz much louder than 50 Hz at the same physical volume (ISO 226 equal-loudness contours). When you boost 200 Hz by +3 dB in ReaEQ, your ears perceive that boost as less than +3 dB. At 3 kHz, the same +3 dB sounds like more.

This converter takes your ReaEQ settings and adjusts the gain of each band so that the perceived loudness change matches what you intended. The math is invisible. You stay in ReaEQ. The psychoacoustics happen here.

Based on AIM EQ (ISO 226 at ~60 phons).
