==Applications==
LPC is the most widely used method in [[speech coding]] and [[speech synthesis]].<ref>{{cite journal |last1=Gupta |first1=Shipra |title=Application of MFCC in Text Independent Speaker Recognition |journal=International Journal of Advanced Research in Computer Science and Software Engineering |date=May 2016 |volume=6 |issue=5 |pages=805–810 (806) |s2cid=212485331 |issn=2277-128X |url=https://pdfs.semanticscholar.org/2aa9/c2971342e8b0b1a0714938f39c406f258477.pdf |archive-url=https://web.archive.org/web/20191018231621/https://pdfs.semanticscholar.org/2aa9/c2971342e8b0b1a0714938f39c406f258477.pdf |url-status=dead |archive-date=2019-10-18 |access-date=18 October 2019}}</ref> It is generally used for speech analysis and resynthesis. It is used as a form of voice compression by phone companies, such as in the [[GSM]] standard, for example. It is also used for [[COMSEC|secure]] wireless, where voice must be [[digitize]]d, [[encryption|encrypted]] and sent over a narrow voice channel; an early example of this is the US government's [[Navajo I]].

LPC synthesis can be used to construct [[vocoder]]s where musical instruments are used as an excitation signal to the time-varying filter estimated from a singer's speech. This is somewhat popular in  [[electronic music]].
[[Paul Lansky]] made the well-known computer music piece [[notjustmoreidlechatter]] using linear predictive coding.<ref>{{cite web | archive-url=https://web.archive.org/web/20171224031037/http://paul.mycpanel.princeton.edu/liner_notes/morethanidlechatter.html |url=http://paul.mycpanel.princeton.edu/liner_notes/morethanidlechatter.html | accessdate=2024-06-02 | archive-date=2017-12-24 | title = More Than Idle Chatter | first = Paul | last = Lansky }}</ref>
A 10th-order LPC was used in the popular 1980s [[Speak & Spell (game)|Speak & Spell]] educational toy.

LPC predictors are used in [[Shorten (file format)|Shorten]], [[MPEG-4 ALS]], [[FLAC]], [[SILK]] [[audio codec]], and other [[lossless compression|lossless]] audio codecs.

LPC has received some attention as a tool for use in the tonal analysis of violins and other stringed musical instruments.<ref name=tai>{{cite journal|last=Tai|first=Hwan-Ching|author2=Chung, Dai-Ting |title=Stradivari Violins Exhibit Formant Frequencies Resembling Vowels Produced by Females|journal=Savart Journal|date=June 14, 2012|volume=1|issue=2|url=http://savartjournal.org/index.php/sj/article/view/16/pdf}}</ref>
