Frequently Asked Questions (FAQs)

Q1: How do I calculate playback speed manually?

Simply divide the original duration by the playback speed. For example, a 10-hour audiobook played at 1.5x speed is calculated as 10 hours ÷ 1.5, which equals 6.667 hours. That's 6 hours and 40 minutes.

Q2: Will I miss important content if I listen faster?

Not necessarily. Most people find they can comfortably adjust by increasing speed gradually (e.g., starting at 1.25x and moving to 1.5x). Studies have shown that comprehension remains high for most people at speeds up to 2x, as the brain can process speech much faster than it is typically spoken.

Q3: What’s the best speed for audiobooks?

The sweet spot for most audiobook listeners is between 1.25x and 1.5x. This range typically maintains the narrator's tone and intent while saving significant time. Faster speeds, like 1.75x or 2x, are often better suited for non-fiction, lectures, or material you are already familiar with.

Q4: How do I plan a movie marathon with a faster speed?

Our Movie Marathon Time Calculator is perfect for this. You can add the runtimes of multiple films, set your playback speed (e.g., 1.25x), and it will tell you the total time needed for your marathon, helping you plan breaks and finish times accurately.
