I have a Fifine K669B USB mic, a laptop (Ubuntu as OS) and an Anker Soundcore 2 Bluetooth Speaker, that also has a 3.5mm audio jack.
Is there a software or a way through an inexpensive hardware, using which I can amplify the microphone output in real time using the speaker?
The idea is to have a small scale megaphone kind of system for a small scale performance. I am a student, so I would like to spend as less as possible.
