Permit Uploads in a Variety of Formats

Recommendation from ​atterer

• The system should allow uploads in a variety of formats, but create the downloads in a canonical format WRT archive type, archive layout, line endings, location/format of prompts file etc.

hum ... as long as they are uncompressed or lossless compressed. I wanted to keep thing simple at first.

• Maybe allow people to upload their saved audacity project. This would make uploads very easy. I'm not sure how difficult it is to decode audacity's xx_data format.

Audacity saves their audio in their own "au" format, I am not sure if Audacity has a command line tool to permit conversions to other formats, or if it is only possible from the GUI. I actually tried to modify Audacity so that users would download an Audacity project file containing label tracks corresponding to the prompts they needed to record, and then click 'control-record' (or something like that) so that the new track wold appear immediately after the prompt track. I was out of my league in attempting to do so - I am sure that with enough time I could probably figure it out (and enough reading of manuals), but I have not had a chance to get back to it.
