What's the impact on the file size?

Forgive me, as I'm not a heavy Voice Memos user, but I'm a bit confused by problem statement.

Voice Memos seem to be ordered chronologically, and named after the location where they were taken (unless manually named), which seems decent unless you star getting a ton.

From the Voice Memos app I can share them to Messages, Mail, etc. Is the issue that you wanted to be able to select a voice memo to share from within Messages, instead of the other way around? Or is this more for posting audio only to social networks that only support video, and having a waveform instead of a random video of something else?

this is really fair comment. I'm one of those iOS users who's life exists in the camera roll/photos app. Screenshots photos pictures of text all live in my camera roll ready for when I need to send or review or save later. What made no sense to me was that I can't dump my audio files into Photos. I really tried to avoid going into files on iOS because it's so cumbersome. so now literally my problem is solved and hopefully someone else is too that I can just quickly save to my photos and send or review from there when I need. To be fair the visualisation is kind of just a way of not having a blank pictured audio file saved to photos.
