bit rate
the number of bits per second that can be transmitted along a digital network. the higher the bit rate the better the quality of the sound.
bit depth
bit depth is the number of bits of information in each sample, if there is a higher it rate this means there will be a better quality on the sound, bit rate can range from 2-bit and 32-bit
