Hello everybody!

I use **Evolution API for WhatsApp** and the audio message is received as in the attached image, Data Base64.

In N8N there is a Convert a File module for audio, but how can we do it here at Make to send this audio to OpenAI for transcription?

Because it was Make, I imagined it would be much simpler and… easier.

I appreciate the help.

Hi,

Welcome to the Make Community!

I’m not sure if I understand your needs correctly.

Whisper works with MP4 files:

So there is no need to convert the file.

And to decode Base64:

Have a great day!
