Can I send a file to Whatsapp from a weblink?

Is it possible to create something like a "Send to my Whatsapp"-Button on a webpage?

I want to share an Audio-file which users should be able to download via Whatsapp in the most convenient way ... they shouldn't need to type their phone number in a field or something like that ... a single click button would be best!

(Sorry, if that question is trivial or was already answered here ... I am no programmer and I won't do it myself ... so I just want to know, if that's possible in general)

Many thanks in advance
