PlaybackCalc

This app helps you make the most of your listening time by calculating exactly how long it will take to finish any audio file when you adjust the playback speed — and just how much time you’ll save in the process.

Whether you’re listening to a 12-hour audiobook, a 45-minute podcast, or a lengthy lecture, changing the playback speed can drastically cut down the time it takes to finish. But what does that really mean in minutes and hours saved?

Are you an audiobook lover, podcast enthusiast, or just someone who enjoys consuming audio content on the go? It’s great for students speeding through lectures, professionals powering through training sessions, or bookworms flying through their reading list.
