I'm trying to save time on a project I'm beginning that will record audio from the connected audio input devices on a Windows XP or Windows 7 PC. In the past I have used the DSPACK components for Delphi 6 Pro to do video capture on a Windows PC, but I am wondering if it is the best solution for doing a project that only needs to record audio, not video. Is DSPACK still the way to go or is their a faster/easier solution to recording audio via Direct3D from the PC's connected audio input devices? Sample rate conversion and other similar features in a suggested solution would be desirable too. Links to tutorials, etc. are also appreciated.

    IMHO DSPack will save you a lot of time if you have already used it –  Aug 28 '11 at 21:24

If you are familiar with DSPack and using DirectShow filters then it is a good choice for the job. DSP-Worx have an audio filter (DCDSPFilter) that provides a range of effects and they also have DirectShow Interface (LameDShowIntf) to the Lame encoder.

You may also want to consider using GMFBridge to reduce latencies to a minimum.
