Remove SDH from SRT
SDH subtitles describe sounds and name speakers for viewers who can't hear the audio. Turn them into regular subtitles: sound descriptions, speaker labels and music symbols go, the dialogue stays.

What counts as SDH
SDH (subtitles for the deaf and hard of hearing) add what a hearing viewer gets from the audio: sound effects like [door slams] or [UPBEAT MUSIC], reactions like (laughs), the speaker's name when they're off screen (JOHN:), and ♪ around song lyrics.
Streaming downloads often only come with an SDH track. Removing the extra text gives you plain dialogue subtitles, which are easier to read and to translate.
Speaker names are only removed when they're in capitals before a colon at the start of a line, like "SARAH:" or "- MAN 2:", so a normal sentence with a colon isn't touched. When a two-speaker subtitle is left with one line, its dialogue dash is removed too.

(Reactions)

Frequently
Asked Questions
What does SDH mean on subtitles?

No, only the ♪ symbols around them. Song lyrics are part of what's said or sung.
Some speaker names in lower case weren't removed.
To avoid deleting real dialogue, only names in capitals are treated as labels. Remove the rest by hand.
