Morphology

de-emphasis = emphasis (semi-transparent) = de + emphasis

The form 'de-' + 'emphasis' is morphologically clear, but the sense referring specifically to signal-processing attenuation of high frequencies is technical and not directly inferable by average learners.

Etymology

De-emphasis comes from de- 'reduce' and emphasis 'stress', and in audio it means lowering the loud, high parts of a sound—like turning down the treble—so the result is softer and less noisy.
