The key component in the whole system is a digital audio converter and mixer. This device has an excellent performance: Audio 10×10 at 24-bit/96kHz or 6×6 at 24-bit/192kHz. There are 10 analog audio input channels and 10 digital audio output channels all mixed together and delivered through a FireWire cable to a computer. The quality is just perfect. The cost of this device is minimal. (FAO has 6 working languages and the floor)
Any computer with a standard sound card and most importantly with a FireWire slot, can do the recording.
Using laptops may be the best solution because this makes the system very flexible and mobile, thus enabling us to serve meetings anywhere;
The application records the digital signal in all possible formats and quality levels. It contains built-in compressors (MP3 and GSM) and filters of all kind. Then the software allows you to individually treat each channel and store files in preferred location; it can automatically deliver registered files over to network drives, FTPs or send them via e-mail. Sound files can be of practically any length, depending on your needs (we created 20 min files for transcribers and 60 min for archiving). On top of everything, the recording can be set to start automatically only at a certain sound level and the whole system can also operated remotely via Internet. The software also creates a database with all the elements of each recording produced, which makes it easy to analyze the results and identify eventual problems.
Again the cost of the application was minimal compared to the output it provides.
The database created by the software is converted in xml and made compliant with RSS format. mp3 and xml files can be posted on an external server, thus are available on the web.
