Why use MPEG-4?
MPEG-4 is an ISO standard supported by a wide range of companies. This means that an MPEG-4 file can be played by many different players, not only on personal computers, but also on cell phones, PDAs, and television set-top boxes. This is a step forward from a proprietary environment, where you deliver content using different compressors and multiple formats–such as Real, Windows Media, and QuickTime–just to serve your Mac and Windows customers. MPEG-4 audio uses the Advanced Audio Codec (AAC). This codec provides better quality than mp3 audio at any given bitrate. At higher bitrates, AAC supports multichannel surround-sound audio.
