The bit Rate reflects the quantity of data processed or transmitted within a specific time. Data is measured as bits, while the duration will be expressed in seconds which results in bits per second. If you are dealing with a large Bit Rate, this unit can be expressed in the form of kilobit (kbps) megabit (mbps) gigabit (gbps), and the list goes on.
When it comes to how much Bit Rate is used in video or audio files, it is often a factor that affects how good the sound is in both instances. In general, the greater the Bit Rate higher, the better quality of the audio. A file's Bitrate can also impact the size of the video or audio file. The majority of the time, files that are of higher quality, with a better Bit Rate, have a bigger file size than those of low quality, which means a smaller Bit Rate.
