I am building a listening course and wanted to check two things:
1. is it possible to accompany an audio file inserted into a slide with the usual controls, especially a seek/progress bar (not to confuse with the slide progress bar), I know it is possible with video, but I can't figure out how to do it with audio. I reall need an audio seek bar because the recordings are quite long.
2. the audio file is quite long, I have compressed it to the point of audible quality loss (requires de-essing now), however, is it possible not to have to reinsert the same audio into a new slide for another set of questions based on it - these audio duplicates make the file huge and I know it will cause problems with access and downloading on the learner side. I'd prefer multiple slides referring to the same instance of the audio file (hope I am clear)
