Audiobook Speed Calculator

Calculate your audiobook length within the given playback speed

Have you ever wished to finish your audiobook a little faster? Whether you are a student trying to accomplish your daily tasks or a business professional struggling with time constraints, increasing the playback speed of audiobooks can save you time. 

Here comes a tool that assists you in finding listening time at various speeds – the Audiobook speed calculator. It can play a minor role in making your life a little easier. You can choose the playback speed that fits your schedule to complete a particular audiobook.

What is an audiobook speed calculator?

The Audiobook speed calculator is an excellent online tool that enables you to adjust the playback speed of an audiobook according to your desired time. You have to provide the total length of the audiobook and playback speed. The tool then calculates the time in which you can cover the whole topic and the time that will be saved. 

Math Formula to Calculate Audiobook Speed

The formula for calculating the total time of an audiobook at a given playback speed is:

Audiobook Listening Time= Audiobook Length / Playback Speed

Total time in seconds = [(Hours * 3600) + (Minutes * 60) + Seconds] / Playback Speed

Total time=  Original time in seconds / Playback speed

How much time will it take to listen to the 3-hour audiobook at 1.25 speed?

Original time in seconds for a 3-hour audiobook = 3×3600 = 10,800 seconds.

Audiobook Speed Calculator
  • If you choose a playback speed of 1.25x:
  • Total time = 10800 / 1.25
  • Total time = 8640 seconds
  • This would be equivalent to 2 hours 40 minutes.
