what is bitrate
the bitrate is the rate, usually measured per second, that bits are streamed to play the file. a 192kbps file pushes 192k bits per second at playback. the higher the bitrate, the more information is reproduced and so generally the higher quality the sound (or video).
The document is archived and information here might be outdated. The Bitrate attribute is a file-level attribute containing the bit rate of the file in bits per second. g_wszWMBitrate. WMT_TYPE_DWORD. This is a coded attribute. This attribute cannot be duplicated at the file level.
