No nasty surprises
Music under the voice, two people talking over each other and a big echoey room are the three things that hurt accuracy most.

Before you ask
Audio → SRT, answered
01Will it work on a music track?＋
It listens for speech, so an instrumental gives it nothing to work with. Songs with vocals are hit and miss — lyrics are not what it was built for.
02Does every word get its own caption?＋
No — it groups speech into phrases people can actually read at a glance. For word-by-word captions on screen, use the editor.
03Will my editor take this file?＋
Almost certainly. SRT is the most widely accepted subtitle format there is.
