Sound
Warm
Also called warmth, dark, laid-back
A warm product has a little extra bass and lower midrange and a little less treble, which makes voices full and the sound relaxed. Taken further it becomes dark or muddy; its opposite is bright.
Warmth is a Tonality word. A gentle lift between about 100 and 300 Hz adds body to voices and cellos, and a slight treble roll-off removes glare, which many listeners find easy to live with for hours.
The cost is detail: a warm tuning can soften transients and hide Air. Whether that is a flaw or a virtue depends on the listener and the recording, and the word carries no judgement either way.
Warm is often paired with Musical in reviews, and contrasted with Analytical.
