{{wikipedia|MP3#Bit rate|Bit rate}}

The '''Bit rate''' or '''bitrate''' of media measures the bits used to store the data per second (kilobits per second, kbit/s or kbps). It is formally defined as the product of (bits per sample) × (samples per second).

Some common bit rates for [[mp3]] files are 128 kbit/s (standard), 192 kbit/s (medium quality), 256 kbit/s (high quality) and 320 kbit/s (highest quality).<br>
A low bit rate (below about 128 kbps) makes for poor audio quality.
