QUANTIZING (QUANTIZATION NOISE) occurs when a sound is digitized (sampled). The amplitude of the sample is restricted to only integer values within a limited range. For example, an 8-bit sample assigns an integer value between 0 – 255 to represent the amplitude of each of the samples. Quantization gives the reconstructed waveform a staircase shape, compared with the original sound’s smooth, continuous waveform shape. As the sampling resolution goes down, the amount of noise due to quantization increases. With 16-bit samples, the amount of quantization error is barely audible.
