What is resilio-sync-audio-service.exe?
resilio-sync-audio-service.exe is a background component of Resilio Sync that monitors, indexes, and synchronizes your audio folders across devices using peer‑to‑peer file transfer. It runs quietly in the background to keep local audio libraries in sync, enabling seamless cross‑device playback and offline access without cloud servers.
This service uses a lightweight daemon that communicates with the Resilio Sync core over local IPC and network peers, coordinating metadata, block transfers, and folder synchronization while observing ignore rules and selective sync settings.
Quick Fact: Resilio Sync’s audio service leverages peer-to-peer syncing to keep music collections consistent across devices without central servers.
