Single Audio track across a whole project Dec 01, 2021 By Jane Cooke Hi, All... I want to use a single audio track across multiple slides in Storyline. I've looked through the discussions and saw one about copying from one slide to all selected slides. That did NOT work for me. Is there a way to have a single audio track play over multiple slides? I've tried snipping the track into the durations for each slide and it comes across very choppy. Help! Thank you!
