C＃WPF窗口大小正在阻止Naudio Wavein / Waveout流
我正在使用Naudio和WPF在C＃中开发混音器软件。
但是我已经面对了一个非通讯behaivour：输出正常播放，但是当我调整MainWindow大小时，输出音频开始启动。如果保持窗口调整大小，则缓冲区已满，并且有例外。看起来调整大小事件正在阻止主线程。
有人建议吗？
_wavein = new WaveIn();
_wavein.DeviceNumber = 0;
_wavein.WaveFormat = new WaveFormat(44100, WaveIn.GetCapabilities(0).Channels);
waveInProvider = new WaveInProvider(_wavein);
volumeSampleProvider = new VolumeSampleProvider(waveInProvider.ToSampleProvider());
volumeSampleProvider.Volume = (float)slider.Value;
MeteringSampleProvider meteringSampleProvider = new MeteringSampleProvider(volumeSampleProvider, 1000);
meteringSampleProvider.StreamVolume += meteringSampleProviderStreamVolume;
_waveOut = new WaveOut();
_waveOut.DesiredLatency = 50;
_waveOut.Init(meteringSampleProvider.ToWaveProvider());
_wavein.StartRecording();
_waveOut.Play();
I´m using NAudio and WPF to develop a mixer software in C#.
But I have faced with a non commum behaivour: the output is playing normally, but when I resize the MainWindow, output audio starts spliting. If keep window resize, buffer got full and a exception is throw. It´s looks like resize event is blocking the main thread.
Has someone any suggestion?
_wavein = new WaveIn();
_wavein.DeviceNumber = 0;
_wavein.WaveFormat = new WaveFormat(44100, WaveIn.GetCapabilities(0).Channels);
waveInProvider = new WaveInProvider(_wavein);
volumeSampleProvider = new VolumeSampleProvider(waveInProvider.ToSampleProvider());
volumeSampleProvider.Volume = (float)slider.Value;
MeteringSampleProvider meteringSampleProvider = new MeteringSampleProvider(volumeSampleProvider, 1000);
meteringSampleProvider.StreamVolume += meteringSampleProviderStreamVolume;
_waveOut = new WaveOut();
_waveOut.DesiredLatency = 50;
_waveOut.Init(meteringSampleProvider.ToWaveProvider());
_wavein.StartRecording();
_waveOut.Play();

如果您使用
waveOutevent和waveoutevent音频处理将发生在背景线程上，这应该有效If you use
WaveOutEventandWaveOutEventthe audio processing will happen on a background thread which should help considerably
