I am a student who wants to try Arduino in high school. I'm still lacking the basics, so I have a lot of questions Using Arduino and rf communication module, I would like to code so that I can send voice data at once using one Arduino board as a transmitter and several Arduino boards as a receiver. When I looked it up on the Internet, there was no case of transmitting voice data using the rf communication module. I wonder if voice data can be transmitted if I change the voice file format and code it differently If this doesn't work, I'm curious about one-to-many communication using Bluetooth or other one-to-many communication examples, examples, processes, etc I left a post before, but it was hard to refer to it because you sent me a blog link. I'm going to do an experiment on the Doppler effect, so what I want is to connect several Arduino boards in a row and receive voice data in turn, so the voice passes quickly???Slowly? I want to make an effectively. I ask for the answers of the true experts and I would like to express my sincere gratitude to those who answered.

First, what you want. If we only investigate the problem of voice data transmission itself... In the first place, the RF module is focused on turning something on and off and will need an AM/FM module to do what you want? At first glance, I think we can start with Implementation of Walkie Talkie. Don't think about voice "data," but why don't you approach the problem with the concept of voice "signal." In the first place, voice data is one of the most demanding areas.
By the way, I'd like to introduce you to the proper attitude of asking good questions rather than Arduino and other engineering knowledge.
