On March 26th, the Zhang Jiang Science Hall in Shanghai played host to a landmark annual event for the global audio industry - the 2025 China International Audio Summit (GAS) officially opened.

As a key barometer of industry development trends, this year's summit brought together nearly one hundred internationally authoritative scholars in the audio field and representatives from over 600 acoustic technology enterprises, engaging in in-depth dialogue around audio technology innovation and its practical industrialization.

At this summit of cutting-edge technological competition, GIEC's independently developed "BestDynamic" audio dynamic optimization technology broke through the field, emerging victorious from fierce competition among hundreds of technical proposals to claim the "GAS Consumer Electronics Science & Technology Innovation Award · Technology Progress Award."

Mr. Yin Zhe, General Manager of the Audio Products Division at Shenzhen GIEC Digital Co., Ltd., delivered a keynote speech as a specially invited guest, titled "Differentiable Quantization Factors: Efficient Model Compression and Performance Enhancement."

The DIFFQ algorithm he innovatively proposed - which simulates quantization operations by adding independent pseudo-quantization noise to model parameters - successfully achieves model compression for audio source separation models, providing the industry with an entirely new approach to solving this technical challenge.

01 "Breaking Through Barriers, Defining a New Industry Benchmark"

In the consumer audio field, dynamic range optimization has always been a core technical challenge.

Traditional solutions have often fallen into a dilemma: with consumers having limited perception of dynamic range, manufacturers are forced to oscillate between "compressing for gain to protect market appeal" and "sacrificing volume for better specs."

Faced with this industry-wide challenge, GIEC forged a different path, pioneering a third way with a disruptive algorithm -

GIEC's acoustic technology team, leveraging the characteristics of randomness in music signals and spectral energy variation, dynamically adjusts the amplitude of the output signal through real-time content analysis, boosting maximum output power while preserving gain. This allows the speaker to deliver delicate detail in quiet passages while unleashing powerful energy in dynamic peaks.

This innovation pushes hardware performance beyond physical limitations. According to real-world test data, devices of equivalent configuration exhibit a notably enhanced dynamic performance after applying BestDynamic technology - truly achieving the technological miracle of "having it both ways."

This breakthrough not only earned industry recognition, but also clinched the GAS Consumer Electronics Science & Technology Innovation Award · Technology Progress Award - an accolade widely regarded as the "Oscars of the audio world."

As a global bellwether for the audio industry, this award underwent six months of rigorous evaluation by an authoritative panel composed of research institutes, e-commerce platforms, and industry associations - conducting a comprehensive assessment across five core dimensions: technological innovation, design innovation, process innovation, intelligent innovation, and originality. Its professional prestige is highly respected throughout the industry.

For GIEC, which has cultivated deep roots in the audio field for 26 years, this trophy is both a certification of technological capability and a decisive move in the brand's global strategy. As a pioneer in China's audio technology sector, GIEC has long upheld independent innovation, with "hearing real needs" etched into its technological DNA. The success of the BestDynamic algorithm not only injects powerful momentum into the development of domestic audio technology, but also sets a new technical benchmark for the entire industry.

As Mr. Yin Zhe, General Manager of GIEC's Audio Products Division, shared at the awards ceremony: "Technological innovation must be rooted in real-world application scenarios. We have always placed users' genuine needs at the core of our algorithm optimization, ensuring that every technical breakthrough translates into a tangible improvement in quality of life."

This "needs-driven" R&D philosophy is precisely the key to GIEC's sustained innovation.

02 "Technology in Practice: The Q25 Hi-Fi Audio"

This award-winning technology has now been successfully integrated into GIEC's newly launched GIEC Q25 Hi-Fi Audio.

As a flagship product co-created by GIEC and QQ Music, the Q25 Hi-Fi Audio not only incorporates the award-winning BestDynamic audio algorithm, but also integrates the latest QPlay 3.0 technology - achieving a perfect fusion of high-quality music content and top-tier audio technology.

The Q25 Hi-Fi Audio features a newly designed acoustic architecture which, combined with the BestDynamic algorithm and QPlay 3.0 technology, faithfully reproduces even the most subtle sonic details in music - whether the grandeur of a classical orchestral work or the nuanced subtleties of jazz, every element is rendered to perfection.

At the same time, built on deep collaboration with QQ Music, the Q25 Hi-Fi Audio transmits 192kHz/24bit lossless master-tape-quality audio over Wi-Fi - with a Wi-Fi transmission bandwidth over 600 times that of Bluetooth - equivalent to 6.53 times CD quality, allowing consumers to experience the authentic, studio-original sound in the comfort of their own homes.

In an era where wireless listening accounts for over 80% of music consumption, the Q25 Hi-Fi Audio's closed-loop "technology + content + hardware" ecosystem liberates users from the constraints of cables, setting music truly free.

From morning podcasts, to midday Wi-Fi direct-connected Hi-Res albums, to nighttime white noise...

The Q25 Hi-Fi Audio seamlessly transitions across all scenarios, unconstrained by wires. Whether in a quiet home setting or a lively outdoor gathering, it effortlessly conveys the magic of music.

QPlay 3.0 lossless transmission technology and BestDynamic dynamic range enhancement technology imbue every moment with depth and texture in the soundstage, transforming music from mere background noise into the art of living.

From a laboratory breakthrough to a market-ready product, the success story of GIEC's BestDynamic audio algorithm is a vivid testament to Chinese technology enterprises' commitment to relentless innovation and the pursuit of excellence.

This award is not the finish line - it is a new starting point.

GIEC will continue to cultivate deep expertise in audio technology, drive industry-wide technological advancement, and deliver ever more awe-inspiring listening experiences to users.

The future is here. Sound becomes experience.

We look forward to GIEC's continued innovation and progress in the audio technology field, bringing even more surprises to users!
