c# - 在 Windows Phone 8 App 中播放音效

Question

我正在使用以下代码播放音频文件，但在代码的第二行出现程序崩溃。可能是什么问题？

这是我使用的代码:

Stream stream = TitleContainer.OpenStream("sounds/bonk.mp3");
SoundEffect effect = SoundEffect.FromStream(stream);
FrameworkDispatcher.Update();
effect.Play();

运行这段代码时出现的错误是:

An exception of type 'System.ArgumentException' occurred in Microsoft.Xna.Framework.ni.dll but was not handled in user code

Answer 1

您是否尝试过使用 .wav 文件而不是 .mp3 文件作为音效？

documentation SoundEffect.FromStream 有一条关于声音文件要求的说明:

The Stream object must point to the head of a valid PCM wave file. Also, this wave file must be in the RIFF bitstream format.

The audio format has the following restrictions:

• Must be a PCM wave file
• Can only be mono or stereo
• Must be 8 or 16 bit
• Sample rate must be between 8,000 Hz and 48,000 Hz
