loudness compensation

Hi everyone, The itch: mixing at low levels changes what you hear. Bass and treble fall away relative to the mids as SPL drops (the effect everyone files under "Fletcher-Munson"). The tools I found approximate this with a broad two-band tilt, so I built the thing I needed: compensation computed...

Ear fatigue is a real cost for producers and engineers and protecting hearing over a long career is something I care about deeply. Some say to monitor at around 85 dB to get a flat representation of the sound, but that's too loud to be healthy. If you lower the level you lose the fun part of the...

APU Loudness Contour is a real-time equal-loudness filter that offers precise control over a wide range of perceptual loudness contours, including ISO 226 (2003 & 2023), Fletcher-Munson, K-weighting, A/C-weighting, ECMA-418, and ITU-R 468. Each contour is normalized to 0 dB at 1 kHz and...

Looking at a few different solutions from Audessey, Monoprice, and JBL to solve the low level listening issue: Speakers that keep bass levels relatively higher at low volumes sound better at low levels that any system of any size at any cost in any room I've ever heard, when compared to systems...
