Important: Keep Arctan running while using calls or dialers. If Arctan is closed, your calling app may not receive the processed microphone audio.

5. Configure Windows Sound Settings

Open the classic Windows Sound control panel. You can search for Sound settings, then open more sound settings or advanced sound options to reach the Playback, Recording, Sounds, and Communications tabs.

Step 1: Set your real speaker as the default playback device

On the Playback tab, select the speaker or headset that you actually listen through and set it as the Default Device.

Then open Properties for that device, go to Advanced, and clear these options when available:

  • Allow applications to take exclusive control of this device
  • Allow hardware acceleration of audio with this device
  • Enable audio enhancements

Step 2: Verify Arctan Microphone is the default recording device

When Arctan is active, the app automatically sets Arctan Microphone as the Windows default recording device. Users do not need to configure this manually.

On the Recording tab, you can verify that Arctan Microphone is shown as the Default Device.
