The MP3 audio recording applet SDK is designed to create MP3 audio recorder on the web site. It allows to record the audio in MP3 format from the web site and upload audio file to the web server via HTTP. Also, it is possible to save recorded audio file on the client computer and open it from there. To playback the recorded MP3 audio from the server the recording applet works in the streaming mode.
