我目前正在使用directsound来获取一个浮点数组来录制音频。
现在我想使用XAudio2(也是SlimDX)播放那个浮点数组,但我不知道该怎么做,因为SlimDX的示例示例播放.wav文件。
以下是他们如何做到这一点:
XAudio2 device = new XAudio2();
MasteringVoice masteringVoice = new MasteringVoice(device);
var s = System.IO.File.OpenRead(fileName);
WaveStream stream = new WaveStream(s);
s.Close();
AudioBuffer buffer = new AudioBuffer();
buffer.AudioData = stream;
buffer.AudioBytes = (int)stream.Length;
buffer.Flags = BufferFlags.EndOfStream;
SourceVoice sourceVoice = new SourceVoice(device, stream.Format);
sourceVoice.SubmitSourceBuffer(buffer);
sourceVoice.Start();
// loop until the sound is done playing
while (sourceVoice.State.BuffersQueued > 0)
{
if (GetAsyncKeyState(VK_ESCAPE) != 0)
break;
Thread.Sleep(10);
}
// wait until the escape key is released
while (GetAsyncKeyState(VK_ESCAPE) != 0)
Thread.Sleep(10);
// cleanup the voice
buffer.Dispose();
sourceVoice.Dispose();
stream.Dispose();
基本上,我想知道如何使用slimDX播放浮点数组?

我不是音频专家,但我知道你可以创建一个IeeeFloat的WaveFormat。填写所有其他信息,然后将数据写入DataStream并将其提供给AudioBuffer。然后你可以正常调用提交。
