With a playback speed calculator, you can calculate the time it’ll take to watch or listen to an audio/video file at a specific speed.
For example, if you have a 2 hour 30 minute 5 second file and you want to watch it at 1.25x speed, the calculator will show you that it’ll take around 2 hours to finish, saving you 30 minutes.
If you increase the speed to 1.5x, you’ll save 50 minutes and finish the file in 1 hour 40 minutes 30 seconds. This way, you can plan your time efficiently!
