MediaPlayer.Volume Property

  • 项目

Gets or sets the media player volume.

Namespace: Microsoft.Xna.Framework.Media
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public static float Volume { get; set; }

Property Value

Media player volume, from 0.0f (silence) to 1.0f (full volume relative to the current device volume).

Remarks

Volume adjustment is based on a decibel, not multiplicative, scale. For example, when the device volume is half of maximum (about 7 in the Windows Phone user interface), setting Volume to 0.6f or less is silent or nearly so, not volume 4 as you would expect from a multiplicative adjustment.

Setting Volume to 0.0 subtracts 96 dB from the volume. Setting Volume to 1.0 subtracts 0 dB from the volume. Values in between 0.0f and 1.0f subtract dB from the volume proportionally.
