Sample comparison studio
The original version uses the starting volumes. The adjusted version uses your current settings; the picture stays the same.
Compare reduction amounts with speech held constant
Try the reduction presets in order and use the same sentence for each comparison. You do not have to mute the music. Choose a volume that lets you hear both the narration and the background music.

FAQ
Before you begin
How is this different from turning down the player?+
The player changes the overall listening level. These presets change only the separate music layer, leaving the narration at its reference level.
How much should I lower the music?+
Begin with the preset, then listen at your usual playback volume. There is no universal setting.
Do the reduction presets affect speech?+
No. The presets reduce the separate music layer only. The voice track remains at its reference level so you can judge the change in masking.
How is this different from the full mixer?+
This page offers quick music-reduction choices with a fixed voice level. The related mixer page exposes independent controls for both tracks.
