What is canon-audio-service.exe?
canon-audio-service.exe is the Canon Audio Service executable that coordinates Canon audio drivers, devices, and software utilities. It helps route audio between Windows apps and Canon hardware (headphones, mics, USB DACs), handle device hot-plug events, and support sample-rate negotiation.
It runs as a Windows service or background process that initializes Canon audio drivers via WASAPI/DirectSound, negotiates sample rates, and manages audio streams. It typically runs as a background service to ensure low-latency, stable playback and mic input.
Quick Fact: Canon's audio service starts with Windows or on device connection to provide seamless routing and consistent latency across supported Canon hardware.
