QDU - Quantization Distortion Unit

A particular quantization process will generate quantization noise that affects the quality of the process. Each quantization process is given a Quantization Distortion unit value to indicate the amount of quantization noise generated. PCM (Pulse Code Modulation) generates 1 quantization distortion unit (1qdu).
