2.1.4 Data Representation

removes the sounds in the frequency ranges that we can’t so easily hear or that least affect the perceived playback quality

leaves out repeated data and instead makes a note of how many times it is repeated

number of times per minute that the sound wave is measured. The higher the sample rate the more accurately the wave is represented.

number of times per second that the sound wave is measured. The lower the sample rate the more accurately the wave is represented.

number of times per second that the sound wave is measured. The high the sample rate the more accurately the wave is represented.

wave gap between measurements of a sound wave being taken.

time gap between measurements of a sound being taken.

time gap between measurements of a sound wave being taken.

number of bits used to store the value of each wave. The higher the number of bits the more accurately the value is
stored.

number of waves used to store the value of each sample. The higher the number of bits the more accurately the
value is stored.

number of bits used to store the value of each sample. The higher the number of bits the more accurately the value
is stored.

the number of bits used.

the number of instructions used.
