Only coding parameters of sound generation model • LPC is an example where parameters are a1, a2, …ak , e(n) • Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency and amplitude is present, then other tones or noise of similar frequency cannot be heard by the human ear • the louder tone (masker) makes the softer tone The Masking Threshold is used by the audio encoder to determine the maximum allowable quantization noise at each frequency to minimize noise perceptibility: remove parts of signal that we cannot perceive
