MediaTek Dimensity Developer Conference 2025 (MDDC 2025) officially released the Viper sound quality AI super-resolution audio engine, which uses the "AI audio stream saving" technology on mobile phone chips to achieve a low-cost leap from standard sound quality to Hi-Res and even master-level listening in mobile devices. The core technology adopts a dual-engine architecture, and through the "physical reconstruction + lightweight computing" mode, it can repair the lost high-frequency signal of the 128kbps standard sound source, restore the highest 192kHz/24bit master-level sound quality, and improve the music restoration by more than 70%.
