Raw PCM is the most basic type of output of Mp3SoundCapture component. Streaming means passing data in small chunks while the total volume of the data may be unknown. PCM is a proper format for streaming of raw data. Stereo sound is a sequence of pairs of samples (left, right, left, right.). PCM format is a simple sequence of sound sample values. The component captures sound via MDX from a sound card in raw PCM format.

We expect DirectX in a version backward compatible with the 2006 interfaces to be installed on virtually every Windows computer (yes, also works on Vista). NET assemblies delegating calls to native DirectX DLLs of 2006. MDX is descended by SlimDX Open Source project which exposes roughly similar interfaces and delegates to the native DirectSound libraries. The MDX project is currently frozen since Microsoft moved to XNA Game Studio Express (a solution rather inadequate just for capturing bits of sound). I chose Managed DirectX (MDX) 1.1 to capture sound. See this website for technical and copyright information regarding the LAME project. This article uses a subset of C# MP3 Compressor libraries written by Idael Cardoso which in turn are partially based on A low level audio player in C# by Ianier Munoz. Or you can just set one boolean property to use LAME DLL and perform MP3 compression on the fly. It outputs data as raw PCM samples or a regular WAV file. NET 3.5 component, providing Sound Capturing functionality for a Windows application.

And for the same legal reason, we can assume that we will not see MP3 functionality in Microsoft technologies soon (there is WMA instead). That's legally complicated due to MP3 patent constraints. However, what you often want to achieve is to store the recorded sound in MP3 file (or send it as MP3 stream). It is said that the next version of Silverlight will provide such functionality. Even designers of WPF and Silverlight 2.0 were focused on graphics so deeply, that they forgot about applications recording sound from user's microphone. It's surprising that there are no components for sound capturing in.
