Virtual Audio Streaming adds a virtual sound card on your system and becomes an enhancement/wrapper of your real sound card. Virtual Audio Streaming lets you Broadcast/Record/Connect all kinds of sounds, no matter whether the sound is from the local audio file, microphone, sound application, online music or online chatting/meeting voice. For example, you can use Virtual Audio Streaming to record Skype meetings, with peoples and your voice mixed together or separated, and then broadcast the conversations to msn messenger or ustream.tv. Please be noted that the software is just like a virtual audio cable and all the sounds are transferred with its internal loopback tunnel, so there is NO any audio quality loss. Virtual Audio Streaming also fixes the 'No Stereo Mix' sound card issue of Vista/Win7. Also, you can use Virtual Audio Streaming together with our virtual webcam software(Magic Camera) to stream both videos & audios. If you are finding a XP/Vista/Windows 7 audio changing tool, Virtual Audio Streaming is also suitable for you. It adds itself in windows system tray and let you select system default playback devices with one click on its popup menu.
