At 1.5x, this audiobook takes 6h 40m.

  • At 1.5x you reclaim 3h 20m compared to listening at normal speed, a 33% reduction in total time.
  • Research on accelerated speech shows comprehension stays high for most listeners at 1.5x to 1.75x - this is the sweet spot most regular audiobook listeners settle on.
  • Listening 1h per day, you will finish in about 6.7 days (roughly 1 week).
  • If you listen to one book per month at 1x, switching to 1.5x at the same daily budget lets you fit roughly 6 extra books per year.

Next stepExperiment with going 0.25x faster than your current setting - most listeners adapt within a few sessions.
