Elias vs Live Link Face

Elias 4 is game-audio middleware and a sound engine for interactive soundscapes and adaptive music. Elias Studio gives composers and sound designers visual scripting for sample-perfect audio graphs combining logic, game parameters, playback, and DSP. Its music system supports instrument and track rules, motifs, stingers, automatic loops, random segments, and musical transitions. Spatialized 3D audio and processing such as filters, compressors, and reverbs are included. While a game runs, users can edit patches, replace sound files, and mix without rebuilding or using sound banks. Unity and Godot integrations are provided, and custom or other engines can be integrated. Listed runtime targets include PC, Mac, PlayStation 5, Nintendo Switch, Nintendo Switch 2, iOS, and Android. Elias is written in C and C++, supports Python tooling and automations, and offers source-code access by separate agreement at higher license tiers. Licenses are per game; console releases cost extra per platform, while same-game DLC is covered. Explorer Standard costs €5,850, paid once, and Colonizer Premium costs €15,000, paid once. A free evaluation version is available by request.

Live Link Face captures facial performances and generates animation for MetaHuman characters in Unreal Engine. The iOS app supports real-time and processed animation and can capture raw video and depth data for the MetaHuman plugin. Epic describes the Android app as a beta for real-time MetaHuman facial animation. Animation streams over a network to Unreal Engine through the MetaHuman Live Link plugin; the phone and computer must be connected to a network. App settings include OSC connections for external controllers and devices. Android timecode can use the system clock, an NTP server, or a Tentacle Sync device for multi-device synchronization. Real-time Android animation is limited to certain Qualcomm chipsets, and Snapdragon 8s chipsets are unsupported; Android does not support capture for offline processing. Live Link Hub can download recorded media from Android and iOS devices and trigger recording on a connected phone. The app is free on iOS and Android. The App Store listing requires iOS 16 or later, while Epic’s workflow description specifies an iPhone 12 or later and a Windows 10/11 desktop PC.
