At any time while you are using Voxal you may wish to mute your microphone. You can do this quickly by clicking the Mute button on the main toolbar. Once this button is clicked, Voxal will not play any microphone audio to any of your applications. If you are currently on a VOIP/Skype call then the person you are talking to will no longer be able to hear you.
You may find that you want to revert back to using your normal voice while using Voxal. To do this click the Bypass button on the main toolbar. Doing so will instruct Voxal to still pass the microphone audio to the application you are using (eg. Skype), but it will no longer apply any effects to it.
