The Wideband Voice Recording Applets SDK allows recording the voice with audio bandwidth limited to 7500Hz from web site, to compress it to 16kbps and to send to the web server via HTTP. To playback the recorded voice from the server the embedded voice streaming player or a separate player as a voice-streaming applet can be used. The voice recording and voice streaming applets are developed in Java 1.1. So, the client does not need to install a big size Java 1.3 plug-in. Both recording and playback applets have a JavaScript interface. So, the developer can customize the JavaScript code correspondingly to scenario and style of the web site.
