Long Recording Memory Issue

[LeonG68]

I’m trying to record meetings (1 hour and 30 minutes) using a desktop app with electron.js and node.js. We are recording a clip, saving it to a file, and then transcribing it with whisper.cpp.

The issue we have is that when the clip is too long:

1- Node.js fs (FileSystem) Module can't handle to write a big Buffer to save into file (crashes)

2- MediaRecorder class saves on Memory which causes memory being full and causing crashes.

We are thinking that for both issues, we need to stream the data of recorder realtime to the file to be saved. Or have it live transcribed like issue #185.

What are your thoughts on how to tackle this problem.
