Hey Squarespace users! I have a site that helps music students and we have a lot of play-along tracks for the books. Does anyone know of a Squarespace plug in or platform I can use on my Squarespace site that will allow students to slow-down the audio to whatever speed they need without changing pitch? I currently have several tracks that are full speed, 80% speed, 60% speed, etc. but it’d be so nice for students to have total control on their end to do whatever speed they need it to be. Any help would be greatly appreciated thanks!
