Summary

In this chapter, we ve covered how to discover and enumerate the various audio capture devices connected to a PC. Once we ve learned the list of audio capture devices available to DirectShow, we ve been able to build capture filter graphs and write these audio streams to disk files. DirectShow can be used as the basis of a powerful audio capture and editing application. (Editing is covered in Chapter 8.) Alternatively, you can use DirectShow for audio playback although there are easier ways to do that, using DirectSound.

Now we ll move along to video capture with webcams. Here compression isn t just an option; it s a necessity because video files can easily fill your entire hard disk in just a few minutes.
