What does bitrate mean?
The bitrate of a broadcast is the average number of bits of data contained within one second of audio.
For example, a typical mp3 bitrate is 64 kilobits per second. The more bits of information, the higher the bitrate; and the higher the bitrate, the better the broadcast will sound. For audio files, a bitrate of 128 kilobits per second or higher typically yields CD-quality sound. mp3PRO encoding allows for the same quality at only 64 kilobits per second.
