Authoring Tools - Upload PPT/Doc/Pdf ,Add audio to individual pages

Hello Friends,

Can we have the following Authoring tools done:

Create a section where Trainers can upload their Ppt/Doc/Pdf online to the portal and  which gets converted into different frames/slides ( page wise) which the Trainer can then select a particular slide/frame and add Audio to that. After adding audio, publish it as a Course ( elearning ) which plays with the audio attached to the slide shown.

Option to scroll forward or backwards.

It should also allow inserting VIDEO link either from Youtube or from our desktop.

Regards

Mahesh
