What is sampling?

In music, sampling is taking a portion, or sample of a recording. It does this with sampling and the sample rate is the amount of time it does it in a second, in millions. The higher the quality of a track, the higher the sample rate and the larger the file size. This effects the time it takes to download because the file is bigger. The sound rate samples in hertz, like clock speed, the better the sound.

What is bit rate?

In computing, bit rate is the number of bits that are conveyed or processed every second. It refers to the amount of bits used to store the different levels of sound at each sampling interval. The higher the bit rate, the higher the quality of the track and the larger the file size. this also effects the time it takes to download because the file size is bigger. The more bitsm the greater range of levels that you can distinguish.

How can audio be represented in binary?

Sound is stored in the computerby taking samples of the sound wave at regular intervals and converting them into binary numbers (using an analogue to digital converter). The computer can then re-create the sound through reversing the process.
