Stereo Imaging Theory
A sound system with good stereo imaging can form apparent sources of sound, such as reproduced musical instruments, in well-defined locations, usually between a pair of loudspeakers placed in front of the listener. These apparent sound sources are called images.
This chapter explains terms related to stereo imaging, how we localize real sound sources, how we localize images, and how microphone placement controls image location.
You can use stereo microphone techniques without reading this chapter. However, if you want to deepen your understanding of what’s going on or develop your own stereo array, it’s worthwhile to study the theory and simple math in this chapter.
First, I define several terms related to ...
