How can I record an audio and save it in a base64 to send through the websocket

[devRafaelMago]

I'm creating a chat system and I need a function to record and receive audios, this communication is done through a websocket, but the mediaRecorder records it in local files, how can I set it to record in QByte or another way that I can convert it to base64 or send it anyway.

CaptureSession{
audioInput: AudioInput {
id: audioInput
}
recorder: MediaRecorder {
id: recorder
}
}
