• The following are optional arguments:

f:WaveFileName          Name of wave file to generate
i:IncludeMP3            If true then the the output will also include an mp3 file
m:MP3FileName           Name of mp3 file to generate

• For example:

MikeyFriedChicken.AudioCapture.exe --WaveFileName "mywavefile.wav" --MP3FileName "myMp3File.mp3" --IncludeMP3 true

How It Works

Define the format for the wave file

WaveFormat waveFormat = new WaveFormat(sampleRate,bits,channels);

Prepare the capture class

WasapiCapture capture = new WasapiLoopbackCapture(latency, waveFormat,ThreadPriority.Highest)

Optionally choose one of the available devices for capturing

foreach (MMDevice device in MMDeviceEnumerator.EnumerateDevices(DataFlow.Render)) 
{
  // Check available devices
}

Start and Stop capturing the audio

_waveWriter = new WaveWriter(filename, capture.WaveFormat);
capture.Start();
// app waits here
capture.Stop();
