C# recording audio from soundcard [closed]

Question

I want to record audio from my soundcard(output). I've found CSCore on codeplex but I could not find any examples. Does anyone know how to use the library to record audio from my soundcard and write the record data onto the harddrive? Or does anyone know a few tutorials on that library?

Answer 1

Take a look at the CSCore.SoundIn namespace. The WasapiLoopbackCapture class is able to record directly from any output device. But keep in mind that WasapiLoopbackCapture is only available since Windows Vista.

EDIT: This code should work for you.

using CSCore; using CSCore.SoundIn; using CSCore.Codecs.WAV;  ...  using (WasapiCapture capture = new WasapiLoopbackCapture()) {     //if nessesary, you can choose a device here     //to do so, simply set the device property of the capture to any MMDevice     //to choose a device, take a look at the sample here: http://cscore.codeplex.com/      //initialize the selected device for recording     capture.Initialize();      //create a wavewriter to write the data to     using (WaveWriter w = new WaveWriter("dump.wav", capture.WaveFormat))     {         //setup an eventhandler to receive the recorded data         capture.DataAvailable += (s, e) =>             {                 //save the recorded audio                 w.Write(e.Data, e.Offset, e.ByteCount);             };          //start recording         capture.Start();          Console.ReadKey();          //stop recording         capture.Stop();     } }
