Explanation:
Detailed explanation-1: -Bit depth. Bit depth refers to the number of bits used to record each sample. As is the case with images, the higher the bit depth, the more accurately a sound can be recorded, but the larger the file size. Typical bit depths are 16 bit and 24 bit.
Detailed explanation-2: -When a sound is recorded for storage on a digital device, the sound wave is sampled at regular intervals and the height of the wave is stored as a number. The number of times per second that the wave is measured is called the sampling frequency and is measured in Hertz.
