このWavレコーディングサンプルを調整しようとしました:http: //channel9.msdn.com/Series/KinectQuickstart/Audio-Fundamentals
新しいSDK(Ver 1.6)に対して、そして何らかの理由で-結果の.wavファイルは無効です
Init:
this.audioStream = this.sensor.AudioSource.Start();
// Use a separate thread for capturing audio because audio stream read operations
// will block, and we don't want to block main UI thread.
this.readingThread = new Thread(AudioReadingThread);
this.readingThread.Start();
fileStream = new FileStream(@"d:\temp\temp.wav", FileMode.Create);
int rec_time = (int) 20 * 2 * 16000;//20 sec
WriteWavHeader(fileStream, rec_time);
スレッド:
private void AudioReadingThread()
{
while (this.reading)
{
int readCount = audioStream.Read(audioBuffer, 0, audioBuffer.Length);
fileStream.Write(audioBuffer, 0, readCount);
}
}
Wavヘッダー:
static void WriteWavHeader(Stream stream, int dataLength)
