Subtitle Edit

Subtitle Edit is a free, open-source Windows tool for creating, editing, and synchronizing subtitles. It supports dozens of subtitle formats (SRT, ASS, VTT), letting users merge or split lines, fix overlapping, and adjust timing. The built-in translator ties into online APIs for multi-language translations. A waveform or spectrogram view helps precisely align text to speech. Subtitle Edit also corrects common OCR errors from DVD/VobSub extractions. Though it lacks AI-based speech recognition, it remains a popular choice for manual or advanced editing tasks with robust features.
