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
