I am currently developing Virtual Classroom with whiteboard,video/audio conferencing. How can I capture microphone using HTML5,Javascript. How can i create base64 encoded string from microphone ? I already capture video image from tag and draw on canvas and received base64 encoded string and broadcast to all students and its works. is any similar way for audio tag also ? i would like to broadcast teacher microphone voice to whole class using socket.io. I found number of tutorial but every body explain about video not audio :( . I am using Chrome -v 21 and able to use webkit. Thanks in advance
