Hi experts,

I used an Attachment Control and uploaded an .wav file, then set onAddFile property of the attachment control with below formula (I'd like to convert the audio to base64 encode by JSON function). Then I set a text label with "Text(filejson)". I expected to get a base64 encode, but I got the appres: returned showing as below, any idea?

I tried to solve. But i also faced the same.
I think we don't have solution for that.
You can use document library instead of that to store all types of attachments there.

Thanks for your investigation!
But what do you mean "use document library instead of that to store all types of attachments"? Actually, I want to implement a function to call speech to text service in Power Apps, so I need to capture an audio of .wav or .ogg format in canvas, then trigger a flow to convert to text. Is there any other way to implement this?
