NVIDIA Broadcast 1.4.0.28

NVIDIA Broadcast 是 NVIDIA 官方推出的免費工具，核心是借助 RTX 顯示卡的 AI 運算能力，把一般房間變成簡易直播或視訊工作室。它最有辨識度的特色，就是能即時處理麥克風與攝影機訊號，例如消除背景噪音、模糊或替換視訊背景，讓線上會議、直播或語音通話的品質明顯提升。這套軟體由原廠持續維護，更新頻率穩定，在同類工具中算是相當熱門的選擇，不過目前僅提供英文介面。

這款軟體特別適合直播主、經常開線上會議或錄製教學影片的使用者，尤其是身處吵雜環境、又不想額外添購隔音設備或實體綠幕的人。與其他免費影音工具相比，NVIDIA Broadcast 的取捨在於它高度依賴 RTX 系列顯示卡，沒有這類硬體就無法發揮功能；若你用的是非 RTX 顯示卡，可能得考慮其他純軟體方案。授權上它完全免費，但僅支援 Windows 平台，且介面只有英文，使用前需留意這些限制。
