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-Only coding parameters of sound generation model
