Huh. So Corbax made a similar page in 2013 that I couldn't find from the search. I like the brevity there, applying that here.

A '''bit rate''' is a measure of bits transferred per unit of time.
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).


As it pertains to music, bit rates are measures of the samples in an electronic music rendition. The ''de facto'' unit is kilobit per second or kbit/s. Common bit rates with [[mp3]] files include 128 kbit/s (standard), 192 kbit/s (medium quality), 256 kbit/s (high quality) and 320 kbit/s (highest quality). A high bit rate does not necessarily make the sound better but a low bit rate (e.g. 32 kbit/s) sounds bad.

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).
A low bit rate (below about 128 kbps) makes for poor audio quality.
