SlimDX 录音(OK)然后播放(问题!)
我目前正在使用 directsound 来录制音频的浮点数组。
现在我想使用 XAudio2 (也有 SlimDX)播放该浮点数组,但我不确定该怎么做,因为 SlimDX 的示例示例播放 .wav 文件。
他们是这样做的:
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?
提前致谢
I'm currently getting a float array using directsound to record audio.
Now I would like to play that float array using XAudio2 (SlimDX also), but I'm not sure what to do since the sample example from SlimDX plays a .wav file.
here is how they do this:
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();
Basically, what I would like to know is how to play a float array using slimDX?
Thanks in advance

我不是音频方面的专家,但我知道您可以创建 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。然后就可以正常调用Submit了。
I'm not an expert on audio stuff, but I do know that you can create a WaveFormat of IeeeFloat. Fill in all the other information, and then write your data to a DataStream and give that to the AudioBuffer. Then you can call Submit as normal.
