AudioEngine Constructor (String, TimeSpan, Guid)

  • 项目

Initializes a new instance of this class, using a settings file, a specific audio renderer, and a specific speaker configuration.

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

Syntax

public AudioEngine (
         string settingsFile,
         TimeSpan lookAheadTime,
         Guid rendererId
)

Parameters

  • settingsFile
    Path to a global settings file.
  • lookAheadTime
    Interactive audio and branch event look-ahead time, in milliseconds.
  • rendererId
    ID that specifies the audio renderer to use.

Exceptions

Exception type Condition
ArgumentNullException The settingsFile parameter is null.
ArgumentException XACT could not load the data provided. Make sure you are using the correct version of the XACT tool.
InvalidOperationException The engine could not be created.

Remarks

The lookAheadTime parameter specifies how far ahead the audio engine will look when determining when to transition to another sound. For sounds linked to Play events that use a wave variation list, this parameter should be set to greater than 250 milliseconds. Doing so should give the audio engine enough time to prepare streamed data before it is needed for the loop iteration.
