What is Digital Audio Processing Techniques about?
Digital audio can be represented by sampling an analog audio signal at regular intervals and quantizing the amplitude of each sample. The Nyquist theorem states that the sampling rate must be at least twice the highest frequency of the original signal to avoid aliasing. Dithering and noise shaping are techniques used to reduce quantization error when digitizing audio. μ-law encoding applies a nonlinear quantization function to allocate more quantization levels to low amplitudes, mimicking human auditory per
