Random question, not important for most people but is there a proper, *designated* way to get WhatsApp to post a message as audio vs document?
If I want to send it as audio to someone so they only have to click the message once, not twice, I send it to myself which appears as document, then from the share sheet, find the person/group I want it to go to, then it goes as audio. This seems long-winded.
From WhatsApp app every audio file is a document, but since both types of message types exist, there has to be a better way.

@FreakyFwoof What filetypes are you using? This is a bit out of my area but I believe it will attempt to treat messages it detects as audio as an audio message; a document is the fallback type for files it doesn't know what to do with. For example I've sent the occasional application and it showed up as a document. Have you tried asking support?

Well here's what I know.
From WhatsApp windows app, *any* audio file appears as document if I CTRL+C CTRL+V it into the app from explorer, or whether I attach it from the attach dialog.
If you send a wave file from let's say, logic to iPhone over airdrop, two things will happen.
1. File gets transcoded using some of the very worse audio codecs known to humans anywhere, sounds like 96 Kbps mp3 from 1998.
2. that same file is 0 seconds long according to the person you send it to, but it still plays.
You can run some tests with me if at all interested. I do a ton of audio on WhatsApp because I'm me, and well you know...

Send it an mp3 file though, no transcoding happens thankfully, as it's already a lossy format, so WhatsApp doesn't eat it for breakfast.
