The Webinato audio system has been optimized for communication via the Internet so that latency and the required bandwidth remain low. As such, all microphones (including those integrated into webcams) designed for computer communication are supported. Webinato uses a specific audio format at 16 khz, which provides clear voice communication (phones use 8 khz for example). 

It is not recommended to play music through your microphone. Instead you should use the Audio Player tool which can stream high quality mp3s or play from a selection of Internet radios. Click here to learn more about Audio Player
