示例

以下示例演示 CaptureEffectsManager.GetAudioCaptureEffects 以检测指定捕获设备上是否存在 DeepNoiseSuppression 效果。

private bool IsDeepNoiseSuppressionSupported()
{
    var captureEffectsManager = Windows.Media.Effects.AudioEffectsManager.CreateAudioCaptureEffectsManager(
        MediaDevice.GetDefaultAudioCaptureId(AudioDeviceRole.Default),
        Windows.Media.Capture.MediaCategory.Speech,
        Windows.Media.AudioProcessing.Default);

    // Check for the presence of DeepNoiseSuppression
    IReadOnlyList<AudioEffect> effectslist = captureEffectsManager.GetAudioCaptureEffects();
    for (int i = 0; i < effectslist.Count; i++)
    {
        if (effectslist[i].AudioEffectType == Windows.Media.Effects.AudioEffectsType.DeepNoiseSuppression)
        {
            return true;
        }
    }

    return false;
}

注解

若要创建 AudioCaptureEffectsManager 的实例，请调用 AudioEffectsManager.CreateAudioCaptureEffectsManager。 或者，可以通过访问 属性从 AudioDeviceController 获取此类的 AudioCaptureEffectsManager 实例。
