A sound wave i plotted on a graph and sample points are plotted on parts of the wave depending on how close the points are together depends on how close the audio is to the original sound however this increases the size of the audio track all the sample points together is a data stream which we can then convert into binary when doing minus numbers in binary we use 7 bit the 8th bit is used to represent if the number is positive or negative
