## Resource

Lucas and Luna explore how Discord moved from a standard WebRTC stack to a custom UDP transport layer, achieving sub-50ms latency and near-zero packet loss during peak gaming events like Call of Duty launches. They break down the engineering decisions behind Discord's transition from a hobbyist chat app to the backbone of 200 million monthly active users, focusing on the trade-offs between reliability and speed. The episode dives into how Discord's team handled jitter buffers, forward error correction, and the shift from Google's libjingle to their own 'Krisp' noise suppression. A concrete look at real-time communication at scale. #Discord #VoiceEngine #WebRTC #Sub50msLatency #ZeroPacketLoss #UDPMux #KrispNoiseSuppression #CallOfDutyLaunch #200MillionUsers #RealtimeCommunication #Scalability #EngineeringCulture #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CTOPodcast #TechnicalLeadership #Architecture Keep every episode free: buymeacoffee.com/fexingo
