Signal Audio Service
signal-audio-service.exe is safe. It's part of the Signal Desktop app and handles audio routing for voice calls and voice messages in the background.
signal-audio-service.exe is the Windows executable for Signal Desktop's audio subsystem. It manages microphone input, speaker output, and audio routing for calls, voice messages, and background audio tasks. It runs as a background service to ensure audio consistency.
This component runs as a background process under the Signal Desktop application, using interprocess communication (IPC) with the main UI process to control audio devices, handle microphone capture, and route VoIP audio through the OS audio stack.
Quick Fact: Signal uses a dedicated audio service to separate real-time voice processing from the main UI, helping maintain call quality even when the window is minimized.
