egisub一款高级字幕制作编辑工具，和其他的字幕制作软件相比较起来，它的发展时间较短，但功能方面却十分强大，不只完整的支援Unicode，也支援超过30个地区的语言编码（ex: Big-5、 GB2312、Shift-Jis），除了具备Subtitle Workshop的字幕预览视窗，它的时间轴调整和VisualSubSync一样使用音频显示。可以用波形图或是声音频谱图显示语音，方便跳过没有对白的部分以及卡拉OK的音节切割(zsh)。

Aegisub is a general-purpose, open-source SubStation Alpha subtitle editor that was created to help in many aspects of subtitle typesetting, timing and editing by correcting flawed features found in the Medusa Subtitling Station and adding many that it lacked.

With many specialized tools to complement the generic, easy to use interface, Aegisub is now the most advanced SSA/ASS subtitle editor in the world. A comprehensive manual (including step by step tutorials) ensures that anyone can be working with Aegisub in a very short time.
