Capture Audio streamed to speakers

hi, I need a Managed .NET solution to be integrated into my application which would capture sound being streamed to speakers. This should be independent of Microphone recording. Second requirement is to transform a particular audio file into a new file but with a different playback rate. Let me know your bid independently for both requirement and time frame. This is a very urgent project. Thanks. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
