The following is an introduction to this type of music

When searching for HRTF display music, you will get an introduction similar to the one below, so I recommend this resource.

Binaural recording

Refers to a special recording method in which a recording microphone is intentionally installed in the ear channel of a simulated human head. Due to the physical structure of the simulated human head, the recording will contain some special spatial information. When listening to such recordings with headphones, a sense of three-dimensional space that is different from the real situation but very wonderful will be produced. Records recorded in this way are also called "head records" and are designed for use with headphones.

Most friends who have listened to headphones know that the effect of replaying music on headphones is very different from that of speakers, especially in terms of "sound field". Although headphones can also create a sound field effect, they are far less natural than speakers. "The most significant flaw of headphones is that the sound field is unnatural" has become common knowledge among audiophiles. What causes this? There are two main factors. First, when music is replayed through a speaker, the sound signal is emitted from the speaker, travels through the air, and reaches the human ear. At this time, the "trumpet sound" heard by the human ear is the same as hearing various sounds in nature. It passes through the auricle, external ear, and ear canal, is transmitted to the eardrum, and is sensed by the brain nerves.

In this process, the refraction, diffraction and diffraction of sound waves by the human auricle, ear canal, human skull, shoulders, etc. will have a certain impact on the sound. In acoustics, this effect is described by HRTF, or "head-related transfer function." It is precisely because of the influence of HRTF that the human brain can judge the direction and distance of the sound based on experience. Even if people are blindfolded, they can still judge the direction and distance of the sound. This is based on the brain's judgment based on the experience affected by HRTF. When listening to music through headphones, the sound is "filled" directly into the ears by the driver unit of the headphones. In other words, the impact of the human auricle, skull and shoulders on the sound is gone, and HRTF does not exist. In this case, the human brain cannot accurately determine the direction and distance of the sound. Many people feel that when listening to music with headphones, the sound field feels unnatural and the positioning of instruments seems to be virtual. The main reason is this. Another reason is that when making stereo recordings, the microphones of the left and right channels are generally several meters or even ten meters apart from each other. The stereo signals obtained from such a distance are poured into both ears by two headphone units only 30 centimeters apart. The usual effect is that most of the sound field seems to be squeezed between the left and right ears, commonly known as the "mid-head effect" "(In-Head Effect).

However, there is a "Dummy Head" two-channel recording method that perfectly solves this shortcoming of headphones. Records recorded with simulated human heads can create a more realistic 360-degree sound field effect than speakers when listened to with headphones. It is by far the most perfect high-fidelity recording and playback method in terms of sound field reproduction. It is impossible to use speakers to create a comparable sound field effect unless countless speakers are used to surround the listener and countless channels are used during recording! However, the beauty of a CD recorded with a simulated human head can only be appreciated by listening to it with headphones. Listening with a speaker cannot give full play to its sound field advantages. Why? This is about the principle of simulated head recording technology.

To put it simply, the simulated head recording method is to place two miniature omnidirectional microphones in the ear canal of a dummy head that is almost exactly the same as a real head (close to the tympanum of the human ear), simulating the human ear. The whole process of hearing the sound. This dummy head has auricles, ear canals, skull, hair and shoulders. Even the skin and bones are made of materials closest to the human body. All of this is for one purpose: to simulate as realistically as possible the effects of all HRTFs experienced by the human ear when hearing sounds.

The signals recorded by the two microphones in this way should be said to be equivalent to the sound heard by the ears of a real person at the position of the dummy head. This two-channel signal cannot be subjected to any post-processing (otherwise it will destroy the authenticity of the "simulated real head") and is recorded directly onto the record. As long as you listen to this record with headphones, you can almost perfectly restore the sound field (360 degrees) of the recording place, as if the listener is in the recording place, because all HRTFs are saved on the record. Replayed by headphones. Obviously, playing this record through speakers will give you a good stereo effect, but it can never be compared to headphones. Because during the speaker playback process, the listener is affected by HRTF again, which interferes with the original HRTF information in the record.

Binaural recording can perfectly restore the 360-degree sound field effect! This should be a great thing. However, simulated head recording is only suitable for headphone playback, which greatly limits its use. Therefore, there are very few CDs recorded with simulated head technology on the market and are difficult to find.

On the famous simulated human head technology website/, there are more than a hundred CDs available for order, but due to the small circulation, most of them are expensive. When enthusiasts order from foreign websites, payment and transportation are very troublesome.
