There are three sampling frequencies most often used in multimedia are 44.1 kHz, 22.05 kHz and 11.025 kHz, 5.1025 kHz.
– The higher the sampling rate, the more the measurements are taken (better quality).
– The lower the sampling rate, the lesser the measurements are taken (low quality).
• The number of bits used to describe the amplitude of sound wave when sampled, determines the sample size (resolution),e.g.
8 bits (256 different values)
16 bits (65536 different values)
A higher resolution will give higher quality but will require more memory (or disk storage
