# Theory behind Linear Predictive Coding (LPC)

• What is the theory behind LPC?
• Why are(were) certain implementations of LPC said to be more tolerant of transmission or encoding errors quantization than other compressed voice encoding schemes?

• Can LPC methods also be used for smoothing or short term "prediction" similar to the use of Kalman filter methods?

• Under what conditions or constraints is the use of LPC valid?
• "Why is(was) LPC said to be more tolerant of transmission or encoding errors than some other compressed voice encoding schemes?" Who said that? I don't know LPC very well, but I thought it had to do with reducing redundancy, which would have the opposite effect. May 23 '12 at 1:41
• This question is misleading as it is on false premise. Please close and rectify this. May 23 '12 at 12:59
• There are multiple questions and premises here. Which one(s) do you think need repairing? May 23 '12 at 13:22
• The statement Why are(were) certain implementations of LPC said to be more tolerant of transmission or encoding errors quantization than other compressed voice encoding schemes? is rather false. Can you cite any reference that specifically tells what is better over other? May 25 '12 at 5:14
• That's actually my question. I heard this somewhere, but don't know why this might have been stated. May 25 '12 at 5:43
