So this is a sequence for an iPhone - I have used Voice Memo because you did - but it could equally be another recording App.
For completeness i have included the recordimg step 
Find Voice Memos App and record something
The Voice Memos App is in the Utilities folder…
I recorded a file by pressing the record button - I changed the name to Dyma fi

Go to Soundcloud and Load Your Recording
From the Home Page, click the upward arrow in the top right corner…
.
…and choose your file which usually appears in recents (if not press browse to find it)…
.
.
…at this point it loads (and there maybe a short delay before it is visible via the steps below…)
Copy Link From Soundcloud To Forum
From your home page choose 'Library’by pressing the image of the books at the bottom of the screen…
.
..click on your profile…(Silhouette)
.
..click on your personal profile link…
.
..your file will appear in the list on this screen… click on the 3 dots next to it…
.
..and choose share.,
.
.
…and select copy link…
.
.
…go to the forum (reply to a post or create a new one so that editor is open) and press paste…
.
.
…a link will be visible…save your post…
.
.
.
The Soundcloud image will become visible and you will be able to click on it, to play it - as you can with this one below..
