![]() ![]() This gives a sense of the sound's position as recorded by the microphones. When a stereo recording is played back, the recording from one microphone goes into the left ear, while the recording from the other microphone is channeled into the right ear. Most people are familiar with stereo sound it is heard commonly through stereo headphones and in the movie theater. Stereo sound is recorded with two microphones several feet apart separated by empty space.No sense of sound positioning is present in monaural sound. Monaural sound is a recording of a sound with one microphone.There's a long history of audiophile interest in stereo and binaural recordings, but 3d sound on a computer is a bit different: There's no way for speakers to do the job as well, because there's no way for them to stop each ear hearing the sound that's intended for the other. When you've got HRTF-massaged two-channel audio already, for instance when you're playing a game, headphones are obviously the best way to get the sound into your head. ![]() 3D game audio uses Head Related Transfer Function (HRTF) algorithms to fake the effects of the pinnae, the head and various listening environments, so that injecting the sound straight into the ear canal can produce the impression of real 3D audio sources. Your pinnae - the outer parts of your ears - strongly influence sound waves that pass through and bounce off them. The way you tell whether a sound's in front, behind or above you, rather than just to your left or your right, is by processing the complex differences in phase, time delay and frequency balance that're imparted to differently located sounds by nearby objects (like walls), and by the sonic characteristics of your head. The reason for this is that you've only got two ears. The nice thing about headphones is that they don't bug your neighbors or your wife- and they're actually the best way to hear surround sound, too:īut for some surround sound, particularly 3D positional computer audio, headphones can actually work better than speakers. I've always been fascinated with 3d positional audio through headphones. ![]()
