Virtual listener approach for Impulse Response Utility
The virtual listener approach is perhaps the most common technique for placing speakers and microphones when you create impulse responses. The goal is to capture the effect of the echoes and reflections coming from all around the space—as heard at the listening position. In this approach, the speakers are set up at the edges of the room, and the microphone is placed in the listening position.
The resulting impulse response should sound like your audio is being played back from the various speaker locations in the space. This method does not require multiple microphones; a single microphone can be turned toward each speaker in turn, and different audio recordings can be made from the same location. The image illustrates the virtual listener approach to setting up five speakers for a five-channel surround impulse response, with one microphone placed centrally in the space.
This method can create the impression of the audio signal being completely immersed in the simulated space.
