Combining .WAV files

[RTW]

Hi everyone,

I'm a bit premature here as I don't have much built yet. My team is creating an API to Google's TTS services that will allow us to record messages based on scripts. Basically, the plan is the user will use PowerApps to create a SharePoint list entry that contains the script of what is to be said. Then, they will use PowerAutomate to make an HTTP request to Google to create the actual .WAV file which will be saved as an attachment. While the API isn't ready yet, I already know the output and how to convert it to a .WAV file.

The issue is that we have a few cases where we need one recording that switches between languages. The way the API will have to function is we will need to make separate requests for each language and end up with one file per language. Is there a way in PowerAutomate I can have these files automatically combine to form one file without the user having to go into any other applications? I did a bit of cursory googling and I can't seem to find anything.

Any help would be appreciated! Even if its a "No, this can't be done."
