Ha "normál" MediaPlayert használsz, akkor:
To adjust audio dynamic range (Quiet Mode)
Using the Quiet Mode feature, you can control the difference between the loudest and softest sounds when you play audio. You may want to reduce this difference (known as the audio dynamic range), for example, when watching movies at night or when listening to music with headphones. Turning on Quiet Mode keeps the sound level more uniform, thereby avoiding wide swings in volume.
On the View menu, point to Enhancements, and then select Quiet Mode.
In the Enhancements pane, click the Turn on link, if visible.
Én mondjuk vagy az Asus DVD-t, vagy a WinDVD-t használom. Ott "Night mode"-nak hívják ezt a funkciót.
