What’s the correct way to send an audio file from a HISE plugin to a backend server?

@David-Healey Okay, How do you mean? I don't see how I can do that because unless the backend server is also running on a users device, it can't access the file using its system path and my backend server is hosted on vercel

@daniel_101 Aha ok, when you said backend I didn't realise you meant a remote system. What about using cURL to upload the file to your server?

You can probably convert the audio file to Base64 and send that way. Only for small files though.

@David-Healey Thanks david, Using cURL sounds nice. Can I use cURL within HISE while in production?
I am currently using the Server.callWithPOST function but I can only send the file in a string format (in base64) or as a multipart/form-data format.

@dannytaurus Thanks Danny, Yes sending it as a base64 string seemed to the best approach and I've tried using the "File.loadAsBase64()" function to do that but the function on HISE did not return a valid base64 string, As I explained in a previous post and as of the latest update, isn't part of the "File" API anymore.
I would be very grateful if there is any other way to convert a file to base64 in HISE.

@daniel_101 Yes I think curl should work across platforms, but older versions of Windows might be missing it. I can't remember the details there.

The function is File.loadAsBase64String(); It's still in the API.

Yes the File.loadAsBase64String() function used to exist on HISE but I did not seem to return a valid base64 string. And as of the HISE version I installed today, the File.loadAsBase64String(); no longer exists. Here's a screenshot picture from the HISE API interface:

HISE version I installed today

Built from the develop branch?

To be honest, I do not know much about how the HISE github repo is structured, but I do not think its from the develop branch, because I downloaded from the Download Installer page on the HISE website. url: https://github.com/christophhart/HISE/releases
