If we need define what Audio Bitrate is, we should understand what bitrate is first. In digital multimedia, bit rate often refers to the number of bits used per unit of playback time to represent a continuous medium such as audio or video after source coding (data compression). The encoding bit rate of a multimedia file is the size of a multimedia file in bytes divided by the playback time of the recording (in seconds), multiplied by eight. In an MP3 player, it is the rate of compression used to encode the file in the audio aspect. The higher the rate is, the better the quality of sound is. However this also increases the file size. However, the sound quality will only be as good as the original recording when increasing the bitrate.
MP3 Format:1. 32 kbit/s - MW (AM) quality
Other Audio Formats:1. 800 bit/s - minimum necessary for recognizable speech
