WebRTC technology is often associated with video calls, live streams, or conference apps, but it can be used for much more. It’s a real-time communication tool that can be used for things like playing online games, co-watching videos, and even playing music together.
Thanks to Ant Media Server’s ultra-low latency streaming solution, we can live in a world that is even more connected. Let’s talk about playing instruments together in real-time and the DuetMaster application.
What is Duet Master?
DuetMaster is an online space where you can play the piano with other people. You can make duets with your friends or other DuetMaster users.
With its support for the MIDI protocol, you can simply plug in your digital keyboard and start learning to play the piano – no complicated configurations required.
How does it works?
DuetMaster uses several libraries under the hood. With the help of these library’s, DuetMaster users can play the piano using the virtual keyboard or plug in instruments that support MIDI Protocol.
To track keystrokes, DuetMaster uses Ant Media Server’s WebRTC Data Channel for real-time communication
Tone.js is a synthesizer and DuetMaster uses it to generate audio signals.
