How is playback time calculated?
We divide original total audio minutes by your multiplier (e.g. 120 mins / 1.5x = 80 mins), providing exact time saved down to the second.
What narrator pace is used?
Our manuscript estimator defaults to the ACX industry standard of 150 words per minute (9,000 words per finished hour).
