Depends on which player I am using, VLC almost invariably at 1.33 times, which does not make audio sound too bad. With Totem real time, simply as I am using an older version and upgrading is planned for later, and on my audio player 1.25 times, so that I can have better concentration. the Youtube web player almost invariably 1.5 times or 2 times, as that does help with much of the material.
