c# - 具有效果的Windows 8.1应用程序音频(NAudio或SharpDX)

Question

如何使用FileOpenPicker或NAudio从SharpDX加载音频文件，并添加flat，Phaser，Echo，Gate，Bit Crusher等Audio FX。

FileOpenPicker openPicker = new FileOpenPicker();
openPicker.FileTypeFilter.Add(".mp3");
openPicker.FileTypeFilter.Add(".wav");
openPicker.FileTypeFilter.Add(".m4a");
openPicker.FileTypeFilter.Add(".wma");
openPicker.FileTypeFilter.Add(".aac");
StorageFile file = await openPicker.PickSingleFileAsync();

Answer 1

这是我对音频文件上的FX音效的解决方案。

播放声音

在开始之前，您需要使用NuGet-Package轻松获得以下软件包:

SharpDX

SharpDX.MediaFoundation

SharpDX.XAudio2

C#

FileOpenPicker openPicker = new FileOpenPicker();
openPicker.FileTypeFilter.Add(".mp3");
openPicker.FileTypeFilter.Add(".wav");
openPicker.FileTypeFilter.Add(".m4a");
openPicker.FileTypeFilter.Add(".wma");
openPicker.FileTypeFilter.Add(".aac");
StorageFile audioFile = await openPicker.PickSingleFileAsync();

MediaManager.Startup();
XAudio2 xaudio2 = new XAudio2();
xaudio2.StartEngine();
MasteringVoice masteringVoice = new MasteringVoice(xaudio2);
AudioPlayer audioPlayer = new AudioPlayer(xaudio2, await audioFile.OpenReadAsync());

AudioPlayer类来自Alexandre Mutel https://github.com/sharpdx/SharpDX-Samples/tree/master/Desktop/XAudio2/AudioPlayerApp
。
在AudioPlayer类中，将构造函数从以下位置更改:

public AudioPlayer(XAudio2 xaudio2, Stream audioStream)

至:

public AudioPlayer(XAudio2 xaudio2, IRandomAccessStreamWithContentType audioStream)

现在，您可以使用audioPlayer.Play(); audioPlayer.Stop();控制音频文件

增加效果

您可以添加一个效果，以便:

SourceVoice sourceVoice = audioPlayer.SourceVoice;
Reverb reverb = new SharpDX.XAPO.Fx.Reverb();
EffectDescriptor effectDescriptor = new EffectDescriptor(reverb);
sourceVoice.SetEffectChain(effectDescriptor);
sourceVoice.EnableEffect(0);
