Note how the spectral features change as a function of source direction. Figure 2 shows the magnitude spectra of HRTFs measured from a dummy head microphone for all locations on the horizontal plane. Note that the spectra are similar up to 6 kHz the significant differences in HRTFs at higher frequencies are attributable to variations in pinna shape. When this procedure is individualized by using the subject’s own HRTFs, the localization performance is equivalent to free-field listening (Wightman and Kistler, 1989a,b).įigure 1 shows the magnitude spectra for right ear HRTFs measured for three different human subjects with a sound source located on the horizontal plane at 60 degrees right azimuth. Any sound source can be virtually located by filtering the sound with the HRTFs corresponding to the desired location and presenting the resulting binaural signal to the subject using properly equalized headphones. A complete description of a subject’s head response requires hundreds of HRTF measurements from all directions surrounding the subject. HRTFs for the left and right ears of a subject specify how sound from a particular direction is transformed en route to the ear drums. They rely on a stored database of head-related transfer functions (HRTFs), that is, mathematical descriptions of the transformation of sound by the torso, head, and external ear. Many virtual-reality audio applications attempt to position a sound arbitrarily around a listener wearing headphones. If the recording and playback are for the same subject and there are no head movements, the results are stunningly realistic. Exact reproduction of the recording is possible through properly equalized headphones. Binaural recordings can be made by placing miniature microphones in the ear canals of a human subject. ![]() Even headphones from brands like Ultrasone ought to give you a wider soundstage thanks to their S-Logic technology.Binaural audio refers specifically to the recording and reproduction of sound at the ears. An open-back headphone or a 3D gaming headphone offers a better ‘concert-like feel’ when compared to others.Īn open-back headphone or a 3D gaming headphone offers a better ‘concert-like feel’ when compared to others. While you can listen to binaural music on all headphones, the kind of headphones will affect the spaciousness of your music and in turn the listening experience as a whole. Just like every human is different, so is every headphone. This method gives a more realistic listening experience as the dummy head mimics how the sound travels into human ears.ĪRE MY HEADPHONES GOOD ENOUGH FOR THAT CONCERT-LIKE FEEL? For binaural recordings, a dummy head is used with powerful mics fitted within the ears. To present a life-like audio image, binaural music is recorded similarly to a stereo recording. These separate microphones are placed at a distance to pick up various information. Similarly, to record music in stereo mode, two mics are used. HOW DO I GET THIS EXPERIENCE WITH MY HEADPHONES?Īudio files are recorded in two ways - Mono and Stereo. When you listen to binaural music you can pinpoint whether the vocalist is standing in front of you, the guitarist is sitting beside you, or the drummer is playing that groovy beat behind you. This delay is hardly noticed as your brain processes it as sound from the same source, but this helps it identify the direction (location) of your friend's voice.īinaural audio does the same. The remaining will bounce off objects in the room before reaching you (your ears).Īlso, if your right side is facing your friend, your friend’s voice will first reach your right ear and then the left one. Only a part of your friend’s voice will reach your ears directly. You hear your friend shouting from one end of the room. You are standing in the middle of a room. The shape of our ears and the time taken for the sound waves to reach them is how you can understand which direction the sound originated. Well, you can do all that right from the comfort of your home! And all you need to experience this is a good set of headphones and a binaural track of your favourite song. ![]() Have you ever wanted to visit every concert to listen to your favourite artist perform live? Or, sit in the studio and watch them record that best selling album. ![]() Have you ever wanted to experience that concert-like surround sound? Now, all you need is a good pair of headphones and a binaural track of your favourite artist to achieve that.
