Introducing 3D Acoustic Manifold & Studio Waveforms What's New: In this update, we are taking vocal analysis to a whole new dimension! 3D Spatiotemporal Manifold (PRO Exclusive): We've brought advanced 3D manifold dimensionality reduction algorithms to your pocket. You can now observe the millisecond-level evolution of your voice in full 360° (Orbit, Front, Top, and Flow views), allowing you to pinpoint subtle shifts in resonance and register transitions. Studio Dynamic Waveforms: The Studio module gets a visual upgrade with high-precision real-time voice waveforms. Instantly visualize your breath support and vocal energy. Core Audio Engine Optimization: Deep architectural tuning of our underlying audio engine significantly improves the sensitivity and smoothness of pitch and formant detection while reducing battery drain during long sessions. Partial UI optimization and bug fixes.

What’s New in Version 1.8.0: AI Core Evolution & Dynamic Island This update represents a significant architectural overhaul for Voice Shadow, integrating Convolutional Neural Networks into our audio analysis core for unprecedented precision. Core Technology Upgrades Sound Engine Overhaul: The core audio engine has been optimized using advanced Convolutional Neural Network (CNN) models. This significantly improves pitch detection accuracy and sensitivity, particularly in low-frequency ranges and during rapid vocal transitions. Smart Studio 2.0: Introducing a new AI analysis model that provides professional-grade vocal parameter visualization. New multi-dimensional vocal metrics are now available to guide your vocal training more scientifically. Interaction & Experience Native Dynamic Island Support: Fully optimized for Dynamic Island and Live Activities on iPhone 14 Pro and later models. Monitor real-time pitch status and recording progress directly from the Dynamic Island without unlocking your device. Refined UI & Interaction: Visual hierarchy and operational logic have been polished across the interface for a more fluid and intuitive user experience. System Optimization Data Architecture Optimization: Re-engineered the personal data storage scheme to enhance data read/write efficiency and security.
