Microsoft announced a line of updates to Sway, its mobile- and web-friendly app for making sleek presentations.
You can now add audio recordings to Sway.but only in the web version. And only to the browsers that support audio recording. Although almost every popular browser (including Microsoft Edge) has audio recording ability. So, that shouldn’t be an issue.
If you’re an Office 365 subscriber, you can enable autoplay for Sways; they’ll advance at a set interval, so you can sit back and just look at the content moving along in front of you. You can tell Sway to loop the presentation continuously if you’d like.
Furthermore, company is also adding view counts to Sway which will allow authors to see how many times their sways have been viewed by users in the My Sways page.
