N Air 実験版 is an experimental live-streaming application published by koizuka that serves as the successor to Niconico Live Encoder, commonly referred to as NLE2. Based on the Streamlabs OBS codebase, the program is designed for users who want to test cutting-edge broadcasting features before they reach the stable branch. Version 1.1.20251203-unstable.1, released as the first and only iteration so far, targets power broadcasters on Niconico Live who need advanced scene switching, real-time audio mixing, and integrated chat overlays while remaining compatible with the platform’s proprietary streaming protocols. Because it inherits the modular architecture of Streamlabs OBS, the software also supports third-party plugins, custom transitions, and hardware-accelerated encoding on both NVIDIA and AMD GPUs, making it suitable for high-resolution game capture, VTuber avatar puppeteering, and multi-camera studio setups. The experimental label indicates that nightly builds may contain undocumented APIs, debug telemetry, or partial implementations of upcoming Niconico-specific services such as viewer interaction widgets and cloud-based asset libraries; therefore, content creators who rely on mission-critical stability are advised to keep a secondary installation of the stable N Air release. Feedback submitted through the built-in crash reporter directly influences the roadmap, ensuring that features like HDR tone-mapping, multi-channel ASIO audio, and IPv6 dual-stack streaming are refined before wider rollout. N Air 実験版 is categorized under Video Broadcasting Software and is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
