### Pre-configure VAD and Process Audio File (C#)

Source: https://github.com/ladenedge/webrtcvadsharp/wiki/Home

This example shows how to configure the VAD with specific operating mode, frame length, and sample rate before processing an entire audio file frame by frame. It calculates the frame size based on the configuration and reads audio data into a buffer for speech detection.

```csharp
using var vad = new WebRtcVad()
{
    OperatingMode = OperatingMode.Aggressive,
    FrameLength = FrameLength.Is30ms,
    SampleRate = SampleRate.Is16kHz,
};

var frameSize = (int)vad.SampleRate / 1000 * 2 * (int)vad.FrameLength;
var buffer = new byte[frameSize];
using var audio = OpenAudioFile(filename);

for (int i = 0; i < audio.Length - frameSize; i += frameSize)
{
    audio.Read(buffer, 0, buffer.Length);
    var hasSpeech = vad.HasSpeech(buffer);
    Console.WriteLine($"Frame {i}: {hasSpeech}");
}
```

### WebRtcVad.HasSpeech(IntPtr, SampleRate, FrameLength)

Source: https://github.com/ladenedge/webrtcvadsharp/wiki/WebRtcVad.HasSpeech()

Analyzes a single frame of audio to detect speech. This overload requires explicit passing of the audio frame, sample rate, and frame length.
