What is viber-audio-service.exe?
viber-audio-service is the background component of the Viber desktop app that handles all audio routing, microphone capture, headset and speaker output, and integration with Windows audio APIs to support calls and voice messages.
It runs as a separate process that uses Windows audio APIs (WASAPI/DirectSound) to route mic and speaker data between Viber and the OS, isolating audio tasks from the main UI for stability.
Quick Fact: Viber’s audio service helps minimize latency and improve call quality by dedicating audio threads separate from the UI.
