Huawei collaborates with the Central Conservatory of Music's Chief Tuning Troupe to reveal the secret to excellent sound quality: jointly exploring acoustic aesthetics

The word aesthetics comes from the Greek word "aisthetikos", which means "the feeling of the senses". Since ancient times, the aesthetic concepts of vision and sound have always been popular around the world, such as the "golden ratio" in paintings, sculptures and architecture, the "Mozart effect" in classical music... In the current digital age, aesthetics and The sensory distance is shortened by terminal devices. If screens, TVs, tablets and other equipment carry the task of expressing visual art, then audio equipment such as TWS headphones and speakers are the carriers of "sound aesthetics" to the audience.

Huawei Audio Innovation Technology Media Communication Conference and "Listen to the Original Sound" concert were held on November 23 at the Opera Concert Hall of the Central Conservatory of Music. Liu Dongfang, President of Huawei Terminal BG Audio and Smart Accessories Product Line, systematically decrypted the super CD-level lossless sound quality of Huawei FreeBuds Pro 3 true wireless earphones for the first time at the communication meeting, and introduced in detail the full range of Huawei audio from hardware, software to lossless transmission. Link technology solutions. In addition, Huawei also invited guests such as professors from the Central Conservatory of Music and the chief arranger of the China Symphony Orchestra to conduct in-depth discussions on the roundtable theme of "lossless audio, using technology to restore art"

If lossless sound quality is technology, then tuning is the art of TWS headphones, a playback device. The author believes that sound source, wireless transmission and tuning. You can think of it as the preparation of a delicious dish: the sound source represents the ingredients and is the basis of the dish. Wireless transmission represents the control of the heat, which determines whether the dish is cooked or not and whether it can be eaten. Tuning is the control of the taste of this dish, which represents the ultimate height of this dish. Only top chefs can make the most delicious food from the highest quality ingredients, and this is exactly what the tuning is.

Of course, this is just for the convenience of everyone’s understanding, taking the production of “dishes” as an example. Strictly speaking, this is not accurate. Because "tuning" is a very professional and emotional thing, a presentation of art, and even related to aesthetics - it requires tuning masters to accurately control every note and have a professional musical aesthetic. As the highest music institution in the country, the Central Conservatory of Music has profound cultural and artistic heritage and abundant talent resources of musicians and music professionals.

To this end, Huawei FreeBuds Pro 3 teamed up with 6 musicians from the Central Conservatory of Music: tenor Xie Tian, ​​pianist Huang Yameng, erhu player Yang Xue, cellist Zhu Mu, composer Zhang Zheng, violinist Jin Haiyin, and six masters formed the "Chief Tuning Ensemble of the Central Conservatory of Music", covering all professional art directions of piano, vocal music, folk music, orchestral music, and composition. They were deeply involved in the sound performance and composition of Huawei FreeBuds Pro 3 Wind testing.

# During the tuning process, Huawei’s technical team used innovative free-field tuning techniques with the help of musicians. Through repeated debugging, Huawei successfully achieved the sound quality of FreeBuds Pro 3, making it feature "transparent high frequencies, surging low frequencies, rich details, and distinct layers". This kind of sound quality brings an artistic journey to consumers, allowing them to enjoy great hearing. Of course, to achieve the effect of "original aesthetics", Huawei FreeBuds Pro 3 is indispensable Strong technical support behind it. Huawei FreeBuds Pro 3 uses Polar code, the core technology of Starlight Connection, to transmit audio signals, which doubles the anti-interference ability of Bluetooth audio transmission. At the same time, Huawei FreeBuds Pro 3 also introduces the new L2HC 3.0 protocol, which can be used with Huawei Mate60 series and other mobile phones to enable the headset to achieve 1.5Mbps lossless Bluetooth audio transmission

In terms of playback, Huawei FreeBuds Pro 3 integrates super-sensing original dual units using digital crossover technology to better restore sound. The unit has two characteristics: low distortion and high transient. The low frequency can reach as low as 14Hz and the high frequency can reach as high as 48kHz, bringing ultra-wide frequency response and true restoration, making the user feel like they are in the opera house.

Based on the user’s actual hearing sense, Huawei FreeBuds Pro 3 also supports a triple hearing sense real-time optimization algorithm, which can match the volume level, human ear structure and wearing status, optimize the wearer’s hearing sense in all aspects and adjust EQ in real time. Keep good sound quality the same.

Written at the end

Huawei’s full-link lossless sound quality technology, from a technical point of view, is the first step towards lossless sound quality for traditional TWS headsets. This is a major breakthrough in the wireless audio industry and the path that China’s high-end audio brands must take. This technology will also promote sound quality innovation in the streaming media industry and further promote the lossless high-quality music industry

From an artistic point of view, the cooperation between Huawei FreeBuds Pro 3 and the "Yangyin Chief Mixing Group" will create a new "Chinese technological innovation, Chinese artistic aesthetics" is a new model of industry-university integration. This is a new window that brings the aesthetics of Chinese musicians to the public. Bring music aesthetics to more mass consumers.

Huawei continues to make extreme innovations and breakthroughs in the audio field, and actively communicates and cooperates with more professional institutions and partners in the industry, committed to To deliver the "original" music experience brought by TWS headphones to every user who uses Huawei FreeBuds Pro 3

This "fusion" process also continues to push China's electronic audio industry to new heights Milestones, as consumers, we are both witnesses and beneficiaries.
