One of the most popular applications for bluetooth are dongles for using with mobiles for handsfree calling. The other wireless audio applications include cordless phones using 2.4 / 5.8 GHz wireless or DECT, wireless Skype phones, WiFi speakers etc. These are all audio applications needing limited number (1-2) of audio channels.

Some audio applications need a lot more channels like an audio conferencing system for 16 people or a PA system covering a school or an audio system for playing background music in commercial buildings. Such applications need wireless technology which can reliably deliver multiple audio channels while ensuring low latency and adequate bandwidth, so that you do not hear clicks, noise or pops, and just hear great sound!

VirtualWire is a leader in wireless mesh technology and can help in building solutions for such applications.
