Most audiobook platforms offer the option to adjust the speed at which the content is played, allowing listeners to increase or decrease the pace according to their preferences. The standard speed for audiobooks is usually around 1x, which means the content is played at its original recorded speed. However, many platforms also offer the option to increase the speed to 1.25x, 1.5x, 2x, or even higher, as well as decrease the speed to 0.75x or 0.5x for slower listening.
On some occasions, if I am listening to a factual history book, I like to rewind and listen back to specific details. The calculator divides the original content length by the new playback speed to show how long it will take at the adjusted speed. For example, a 2-hour video at 1.5x speed will now take 1 hour and 20 minutes. When you input the audiobook length, you will typically provide it in hours, minutes, and seconds. Use the recommended playback speed settings on your audiobook player or app.

When we train our brains to listen at rapid speeds, we become accustomed to the new volume of information. There is so much access to playback speed control available to us. Our senses become inundated and adjust to the new stimulus so that our brains crave more and more constant input. A fast-paced thriller might be enjoyable at 1.5x speed, while a complex textbook might require slowing down to 0.8x. Tools like the audiobook calculator speed help you find the sweet spot. Sometimes, if I haven't listened to an audiobook for a few days, I like to rewind and playback in order to recap and get back into the flow of the book.
