Challenges we ran into

Latency Management:
Ensuring minimal latency across different devices was a significant challenge. Variations in network conditions and device capabilities could lead to delays in playback, affecting the user experience. We had to implement strategies to measure and adapt to latency in real-time.

Distributed Peer Connection:
Handling distributed peer connections, especially across varied network setups, was a challenging aspect of the project. We managed network differences by continuously emitting timestamps from each peer to the backend using Socket.IO. The backend processed these timestamps and broadcasted them back to all clients, ensuring synchronization despite differences in network latency and conditions. By monitoring and adjusting for these variations, we ensured seamless connections between peers, maintaining playback sync.

Synchronization of Playback:
Keeping the music playback in sync across all connected devices was a critical challenge. We needed to develop a method to monitor playback states, adjust for any discrepancies, and ensure that all devices were playing at the same time, even if one device experienced a temporary lag.

De-sync Handling:
When de-sync events occurred, whether due to network interruptions or user actions, implementing a reliable recovery mechanism was crucial. We had to create a strategy for quickly resyncing devices to avoid disruptions in the listening experience.
