What is the simplest way to continuously sample from the line-in using C#

Question

I want to continuously sample from my PC's audio line in using C# (then process that data). What is the best way to do the sampling?

Answer 1

You can do some (basic) audio capture using the open source NAudio .NET Audio Library. Have a look at the NAudioDemo project to see a simple example of recording to a WAV file using the WaveIn functions. NAudio also now includes the ability to capture audio using WASAPI (Windows Vista and above) and ASIO (if your soundcard has an ASIO driver).
