There are several really good tutorials on Voicemeter on YouTube. I do believe there's even a tutorial on using Skype with voicemeter. Also, if you download Voicemeter or their other amazing products. please make a small donation to the developer, as this will help keep their site up and enable them to further develop products like voicemeter. Clearly they make it an effort to keep their products inexpensive to the end user.
