At the Masterclass New Technology we should people how to upload files to the Internet Archive via a web browser using windows. It is quite a clunky process.

Much easier is to use the CcPublisher

ccPublisher is a tool that does two things: it will help you tag your audio and video files with information about your license and it allows you to upload Creative Commons-licensed audio and video works to the Internet Archive for free hosting. You also have the option of publishing the licensed and tagged audio works on your own site.

I made a movie of using the tool to ccpublisher_mac1.mov upload a mp3 Quicktime file 3.3 MB stored on the Internet Archive
