Bit rate Definition - What is a Bit rate?
The "bitrate" refers to how many bits (unit for measuring storage space) per second a piece of audio takes up. One byte is equal to eight bits. Therefore, a piece of audio with a 192Kbps bitrate uses 24 Kilobytes of storage space per second of audio. The higher the bit rate of a piece of audio, the lower the compression. The less compression that is used to digitize a piece of audio, the higher quality the resulting digital file will be.
