Vectir is an audio visual (AV) management application that lets you remotely control popular media or MP3 players such as Winamp, iTunes and Windows Media Player. It can also control other features of your operating system such as moving the mouse pointer, adjusting the master sound volume and shutting down your computer. It works with USB infrared receiver devices such as the USBUIRT and Tira2. These devices pickup signals from most infrared (IR) remote controls and send them to your computer.
