About this tool
SDH (subtitles for the deaf and hard of hearing) add information for viewers who cannot hear the audio: [door slams], (laughing), ♪ symbols around song lyrics and speaker names such as MARA: before a line. If you can hear the soundtrack, all that text crowds the screen.
The remover deletes anything inside square brackets or parentheses, upper-case speaker labels followed by a colon at the start of a line, and music note symbols. Lines left empty are removed, a leftover dialogue dash on a single line is cleaned up, and cues with no text at all are deleted.
Lyrics between ♪ symbols are kept as normal text, and lowercase words followed by a colon (for example “Note:”) are left alone. Check the result in the cue list — Undo brings everything back if something was removed that you wanted to keep.
FAQ
What is the difference between SDH and closed captions?
Both describe sounds and identify speakers. Closed captions are a broadcast format turned on by the viewer; SDH is the same idea delivered as a subtitle track, common on Blu-ray and streaming services.
Will this remove song lyrics?
No. Only the ♪ symbols are removed; the lyrics stay. Delete lyric lines by hand in the editor if you do not want them.
Does it remove speaker names in mixed case?
Only upper-case labels such as JOHN: are removed, because mixed-case words before a colon are often normal dialogue.
