The conaito VoiceMail SDK is designed for web developers and allows to record and send voice messages from web sites to any existing e-mail client software, even to free web based e-mail like Hotmail and Yahoo. The recipient receives the usual e-mail message with link to Mp3 audio file. Recipients can listen the Mp3 file by any existing Mp3 player. Mp3 players are installed almost on the each computer, so, no problem with playback!

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.

The conaito VoiceMail SDK uses native methods to sound capture, LAME MP3 encoding/ decoding and playback in the DLL, which will be installed on the computer when user uses the applet for the first time. The recording applet is already digitally signed.

The conaito VoiceMail SDK is compatible with Windows 98/NT/2000/ME/XP/2003/Vista, MacOS X and with Microsoft Internet Explorer 4.0 and up, Netscape 7, FireFox, Mozilla, Opera browsers. On the Mac with Safari and Opera.

conaito VoiceMail functionality

The idea of voice mail is very simple. Web voice mail application creates the text and voice messages and send them to web server via HTTP by POST method. On the server side the server scripts create usual e-mail message body with text message and with link to Mp3 file (voice message). Mp3 file is stored on the server. Server script passes the e-mail message body to Mail Transfer Agent, which send it to recepient. Recepient receives the e-mail message with text and link to Mp3 file and downloads and/or play Mp3 file.

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.

To voice message recording the Mp3 audio recording applet is used. The functionality of recording applet is following:

1. Audio is captured from sound card. The sampling frequencies are 8000Hz, 11025Hz,     16000Hz, 22050Hz, 24000 Hz, 32000Hz, 44100Hz and 48000hz.
2. LAME Mp3 audio encoding/decoding.
3. Playback of the recorded Mp3 file for sound quality and content evaluation.
4. Uploading of Mp3 file to web server via HTTP. The server scripts (PHP, ASP or ASP.NET) is     used to receive Mp3 file on the server. Also, it is possible to save/open/delete audio file     on the client computer.
5. Send VoiceMail with Link to the recorded Mp3 voice message. Also, is it possible to     playback of the Mp3 files from the web server in the streaming mode.

The demo version will allow only 20 seconds of recording only.

The Mp3 audio recording applet is developed in Java 1.1. So, the applet works with Microsoft Java 1.1 (i.e. Recording applet works on the target browsers with default browser JVM installation) and with Java plug-in 1.4-1.6. The recording applet uses native methods for sound capture and LAME Mp3 encoding/decoding. They are developed in C++ and implemented as DLL (jaudioMp3Win.tar and jaudioMp3Mac.tar). The DLL will be installed on the client computer if the applet is being used for the first time. The recording applet is digitally signed. For digitally signing the comodo certificate is used.
