我目前正在使用directsound錄製音頻的浮點數組。SlimDX錄製(確定)然後播放(問題!)
現在我想用XAudio2(SlimDX也可以)播放該浮點數組,但我不確定該做什麼,因爲來自SlimDX的示例示例播放了一個.wav文件。
這裏是他們是如何做到這一點:
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,我想知道的是如何發揮使用slimDX float數組?
在此先感謝
