Video injections are often in higher quality audio and are easier to use, so make sure to check if you can use those first. This is a software solution, which means it demands more from your computer and the result can vary. Many different options for software are available. Select the input or 'virtual microphone' in WebinarGeek after mixing the sound. This is often done with external equipment, but you can also virtually mix the audio, without needing any additional equipment, by using software.
