Answer 2

Answer :

d) The timestamp [inaudible 00:01:50] will be used to mark something that you can’t hear in the audio file.

Cambridge English Dictionary defines 'timestamp' as 'a record in printed or digital form that shows the time at which something happened or was done.'

A timestamp should be timed within two seconds of the speaker's first utterance. In the transcript, the "hh:mm:ss" of the beginning of the inaudible speech should be replaced with the timestamp [inaudible hh:mm:ss].
