“I listened to audiobooks at 1.5x speed for years. I had tried 1.75x, but found it a bit too fast for comfort. Recently, I tried going up 0.1x every couple books, and now 1.9x is perfectly usable. This is a substantial benefit!” John Carmack
Would be interesting if the site offered more playback speeds between 1x and 2x. Could be helpful when doing “quick” reviews for note taking.
