Recently, at a press conference in Shenzhen, the music technology brand LiberLive publicly unveiled for the first time the core technology of its second - generation flagship product, the C2 Stringless Guitar - the high - dynamic sampling synthesis system LiberAOS.

The LiberAOS system independently developed by LiberLive is the world's first high - dynamic sampling synthesis architecture specifically designed for stringless guitars. By integrating four major modules: signal capture, processing core, audio engine, and acoustic output, this system constructs a complete intelligent music workflow.

In terms of technical architecture, LiberAOS is developed around two key dimensions: at the interaction level, it achieves precise real - time response through an optimized signal processing system; at the sound quality level, it relies on a professional tone library and dynamic processing technology to ensure that the sound performance reaches a professional standard. This design retains the essence of traditional guitar playing while integrating the interactive advantages of smart devices. By synergistically improving the operation smoothness and sound quality authenticity, it provides technical support for the stringless guitar in multiple scenarios such as stage performances, professional creation, and interest practice.

The core of the LiberAOS architecture is a multi - core heterogeneous chipset independently developed by LiberLive. As the data processing center of the entire platform, through the induction matrix composed of the self - developed drone magnetic pick and the high - precision force - controlled fretboard, the system can accurately capture every subtle movement of the user during the performance; from the change in the pressing force of the fingertips to the tilt angle of the fingers when picking, it can extract multi - dimensional signals including force, angle, and frequency in real - time, and achieve in - depth restoration and accurate translation of the performance intention.

Compared with smart musical instruments on the market that can only provide basic sound - producing functions, LiberAOS is more like a highly integrated embedded audio workstation. Its four - core parallel architecture is like four professional arrangers working together, which can provide stable computing power support during real - time performances. The audio engine independently developed by the R & D team acts as an intelligent producer, capable of analyzing the performance intention within milliseconds and accurately calling matching sampling resources from a dynamic tone library of tens of millions of samples.

To ensure that the sound has the real texture of musical instruments and natural musical expressiveness, the LiberLive team collaborated with multiple professional acoustic laboratories to systematically sample classic guitar models of well - known brands such as Martin and Taylor, and simultaneously expanded to multiple types of musical instruments such as pianos, drum sets, and basses.

For just one guitar, the sampling period lasted as long as one month, covering multi - dimensional parameters such as different pick materials, string - touching angles, performance forces, and even the tactile differences between nails and finger flesh. These captured subtle tone changes together form a massive dynamic sound source library unique to LiberLive.

It can be said that behind each note is not a single audio file, but a multi - version tone collection library with fine - classified performance forces, techniques, and emotional characteristics, ensuring that the output of each note can accurately match the user's current musical expression and emotional state.

In the output stage, the C2 is equipped with a dual - frequency speaker system, which consists of a silk - titanium film treble unit and a 3.25 - inch bass enhancement unit. Through professional acoustic tuning, it achieves a clear - layered and dynamically rich sound performance. Even without an external audio system, this system can make the instrument performance present a sound quality with a sense of space and on - site presence, meeting the needs of small - scale on - site performances.

By constructing a complete technical closed - loop from signal perception, intelligent processing to acoustic output, while continuing the user - friendly feature of "getting started in one second", the LiberLive C2 achieves an experience upgrade with the LiberAOS system. It not only provides innovative functions such as intelligent singing and melody follow - up singing, supports multi - scenario music mode switching, but also helps users quickly achieve the creative experience of "composing a song in 30 seconds" and maintains a sound quality close to that of a professional recording studio, truly breaking through the traditional boundary between user experience and professional standards of smart musical instruments.
