C# MP3 Sound Capturing/Recording Component

I am a .NET developer, working currently in the UK, though still strongly associated with Poland. Primary interests: business application, server-side, enterprise-scale solutions, SOA, thin but rich internet clients (Silverlight).
Apart from my everyday work, I spend a lot of time validating design patterns for newer technologies (like Silverlight, WCF, LINQ). My warzone is www.nauka-slowek.org - a proof of concept for asynchrony, internet multimedia and command pattern in client-server apps. I also use that website myself as it is a great tool to effectively learn vocabulary (foreign languages), which aids my long being abroad.
