通用应用程序中的多个音频流(运行时 API)，XNA SoundEffect 替换

本文介绍了通用应用程序中的多个音频流(运行时 API)，XNA SoundEffect 替换的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

由于 XNA SoundEffect 在 Windows 运行时 API(用于开发通用应用程序)中不再可用，我需要类似的东西来同时播放多个音频流.

As the XNA SoundEffect is no longer available in the Windows Runtime API (for developing Universal App), I need something similar to play multiple audio streams at the same time.

要求:同时多次播放同一个音频文件.

Requirements:Play the same audio file multiple times, simultaneously.

以前使用 SoundEffect 实现 Silverlight:

Previous Silverlight implementation with SoundEffect:

// Play sound 10 times, sound can be played together.
// i.e. First sound continues playing while second sound starts playing.
for(int i=0; i++; i < 10)
{
    Stream stream = TitleContainer.OpenStream("sounds/Ding.wav");
    SoundEffect effect = SoundEffect.FromStream(stream);
    FrameworkDispatcher.Update();
    effect.Play();
    // Wait a while before playing again.
    Thread.Sleep(500);
}

SoundEffect 支持同时播放多个(我认为最多 16 个)SoundEffectInstance.

SoundEffect supports multiple (up to 16 I think) SoundEffectInstance being played simultaneously.

标准 MediaElement API 仅支持 1 个适用于 Windows Phone 8.1 的音频流.

The standard MediaElement API only supports 1 audio stream for Windows Phone 8.1.

我遇到了这个:https://github.com/rajenki/audiohelper 使用 XAudio2API 但它似乎也不支持同步音频.

I bumped into this: https://github.com/rajenki/audiohelper which uses the XAudio2 API but it doesn't seem to support simultaneous audio either.

Solved. I used SharpDX. Huge thanks to the author here: http://www.hoekstraonline.net/2013/01/13/how-to-play-a-wav-sound-file-with-directx-in-c-for-windows-8/?utm_source=rss&utm_medium=rss&utm_campaign=how-to-play-a-wav-sound-file-with-directx-in-c-for-windows-8

这是解决方案的代码:

初始化:

        xAudio = new XAudio2();
        var masteringVoice = new MasteringVoice(xAudio);
        var nativeFileStream = new NativeFileStream("Assets/Ding.wav", NativeFileMode.Open, NativeFileAccess.Read, NativeFileShare.Read);

        stream = new SoundStream(nativeFileStream);
        waveFormat = stream.Format;
        buffer = new AudioBuffer
        {
            Stream = stream.ToDataStream(),
            AudioBytes = (int)stream.Length,
            Flags = BufferFlags.EndOfStream
        };

事件处理程序:

        var sourceVoice = new SourceVoice(xAudio, waveFormat, true);


        sourceVoice.SubmitSourceBuffer(buffer, stream.DecodedPacketsInfo);
        sourceVoice.Start();

SharpDX的sample官方提供的代码没有使用NativeFileStream，需要它才能工作.

The officially provided code by SharpDX's sample does not use NativeFileStream, it is required to make it work.
