How to use the software?

In order to use the software, download the archive and save it to a folder on your hard drive.
The software contains a command line Nero AAC Codec without a graphical user interface. The applications must be retrieved either from the command prompt, batch file, or from the "Run" command in Microsoft® Windows™ start menu.

The encoder requires .WAV files in PCM wave format as input and provides .MP4 in MPEG-4/3GPP file format as output, as well as quality and bitrate values as parameters. The decoder requires input in MPEG-4/3GPP file format and provides PCM wave files as output.

For more detailed information about the basic and advanced options of the codec, refer to the readme.txt file provided in the archive.
