File Size

VPL has this guide that includes information about compressed data and lossless/lossy files (which cover multiple format types but especially relevant for audio files) https://www.vpl.ca/guide/inspiration-lab-general-technology-skills/file-size

In terms of guides for HOW to reduce file size of a/v materials, I'm also not finding much in the way of guides that aren't just blog posts (which seems weird to me, so I'll need to do some more digging) - Not sure how people feel about using Vimeo as a source, but their video compression post actually seems pretty straight forward and will hopefully be a somewhat stable link? https://vimeo.com/blog/post/how-to-compress-a-video/#how-to-compress-a-video-in-ios-and-on-macs

A lot of the other search results I get are direct links to file compressors, but I don't usually like to directly link to software that UBC doesn't work with
