What is lossless sound quality Part 7
Assuming you really have a good sense of hearing, investing in better hearing equipment may be the most straightforward option.
According to the author’s experience, headphones with a certain level can help you hear the details and dynamics of music, and even if the mobile phone can support lossless files The occupation mode matches the Bit-Perfect playback output, and the listening experience is still not as good as using SRC mode with a slightly higher level external audio device. After all, the external audio device has relatively ideal circuit isolation and higher quality audio grade components and a more abundant driving force will make the music heard in the headphones more layered and full.
However, the sound here refers to the form of the sound. If you listen to the compressed file with a better external audio device, you will find that the sound connection is still quite broken and the fineness is not ideal. The atmosphere is better without being noticed at first glance, but looking back, how many opportunities and moods are there to listen to the details so carefully, so if the author chooses, the author will still give priority to improving the quality of the headphones and external audio equipment. quality.
Why Apple believes that spatial audio is a technology that can lead the music trend more than high-quality sound
▲ The focus of spatial audio is to break the limitation of listening to the left and right channels of stereo headphones, making the listening feeling more three-dimensional
The last thing I have to mention is that Apple put support for spatial audio technology before providing high-quality sound in the Apple Music revision. One, of course, is that Apple hasn’t completed the SRC of the playback software, and most people can’t distinguish between lossless and compression sound quality. The difference in sound quality is no coincidence that Sony is also promoting 360 Reality Audio technology with similar features. It can be said that the important point of spatial audio technology is to break through stereo and even break through the innate limitations of headphones.
Because compared to the speakers that are placed in an open space and transmit the sound by direct exposure and reflection in space, and finally heard by the human ear and produce a sense of space, the headphones directly connect the left channel and the right channel. right. is transmitted to the left ear and right ear, but the earphone will not be able to hear a part of the right sound as a speaker, and the right ear can also hear a part of the sound from the left ear. This is also the key for many music players who believe that speakers still appreciate more than headphones.
▲ Sony’s 360RA is further corrected for ear type data and can be optimized for specific headphones and speakers
But after all, most of today’s music formats use stereo as a reference point, but do not take into account the differences between headphones and sound devices. Once recorded in traditional stereo, it is difficult to change the innate limitation of the headphone listening experience; The technology allows headphones to simulate the flat sound field of speakers, but in analog, sometimes the spatial position of the sound gets weird.
Whether it’s Dolby Atmos, which is the basis of Apple’s spatial audio technology, or Sony’s 360 Reality Audio, in the post-production process, the music creator defines the sound space and uses analog technology to create the corresponding frequency in the sense of hearing It can not only overcome the flat sound field of traditional virtual surround sound, but also because it is a real spatial positioning narrative, it can also hear the listening feeling that is closer to the original creator’s desire to express.
To listen to music with headphones, it can help break the original stereo playback positioning method, so that at first glance the sound can be as three-dimensional as using a speaker, and the user’s sense of hearing will be more direct than enhancing the details . Of music It is also easier to feel the difference with the general public’s sense of hearing, of course, spatial audio technology is also suitable for multi-channel speaker systems, and multi-channel speaker system and spatial audio is expected they complement each other.
