From Stenography to Recorded Tape
Launch library · evergreen read

Before reliable recording technology existed, interviewers relied on shorthand and memory to capture a conversation, a method considerably more prone to error and compression than a full audio record, however skilled the individual stenographer happened to be. Errors crept in easily, however skilled the individual stenographer happened to be at the task.
The arrival of portable recording technology changed the craft substantially, allowing interviewers to focus fully on the conversation itself rather than dividing attention between listening and the demanding, simultaneous task of writing everything down accurately as it happened. That freedom changed the quality of attention an interviewer could bring to the actual conversation.
This shift also raised the bar for accuracy: a recorded interview can be checked and re-checked, holding both interviewer and subject to a standard of precision that a stenographic record, however carefully taken, could never fully guarantee. Reliable recording remains, even now, one of the quieter but most consequential advances in the craft's history.
