c++ - Capture audio of a single application on Windows 7

Question

Is there a way to capture the audio outputted by only a single application, and not the system as a whole? With WASAPI I can capture the entire system audio, but I wish to only capture the audio from one application (there will be many applications, all playing audio at once.)

Answer 1

Detours is used for hooking. Using the lib to hook IAudioRenderClient interface, including GetBuffer and ReleaseBuffer, and read data from the buffer.
