Passing large audio file to another application

Hi, I’m looking for a solution to a specific issue and wonder if anyone has any ideas. I’m recording a conversation using one of the free audio recorder plugins, which works very well except for the fact that my resulting files are often larger than Bubble’s 5MB limit (the latest one, for example, is a one-hour conversation, which is 65MB).

I don’t actually want to save this audio file - what I want to do is pass it automatically to Assembly.AI for transcription (using the feature that identifies the different speakers, so it needs the audio file rather than being live) and then to save the resulting text. Does anyone know how I can do this? Thank you!
