In digital signal processing, linear prediction is often called linear predictive coding ( LPC ) and can thus be viewed as a subset of filter theory.

In order to accomplish this he wrote what is nowadays known as a virtual machine, which he called the LPMud driver, that ran the C-like LPC programming language used to create the game world.

Linear predictive coding ( LPC ) is a tool used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model.

LPC starts with the assumption that a speech signal is produced by a buzzer at the end of a tube ( voiced sounds ), with occasional added hissing and popping sounds ( sibilants and plosive sounds ).

LPC is frequently used for transmitting spectral envelope information, and as such it has to be tolerant of transmission errors.

LPC is generally used for speech analysis and resynthesis.

APC is related to linear predictive coding ( LPC ) in that both use adaptive predictors.

For example, LPMud tries to avoid the stability risks by abstracting the system into a virtual machine which is protected from mistakes made in objects written in the game's LPC programming language.

LPA is the first North American ' little people ' organization, with the Little People of Canada ( LPC ) incorporating in Canada in 1984.

The Nightmare Mudlib is a set of LPC programming language frameworks created by George Reese for building multi-user role playing games using the MudOS LPMud driver.

LPC ( short for Lars Pensjö C ) is an object-oriented programming language derived from C and developed originally by Lars Pensjö to facilitate MUD building on LPMuds.

Almost everything in LPC is an object.

However, LPC does not precisely use the concept of a class ( MudOS has something called a class, but it is really a struct ).

In LPC, it is not possible to syntactically declare class-only or instance-only methods and attributes ; all functions and variables may be accessed identically in blueprints and in clones.

Because LPC is generally used to code MUDs, ' rooms ' are often created as objects that store information describing a particular scene along with exits that point to other room objects.

This is the most common usage of LPC.

MudOS is a major family of LPMud server software, implementing its own variant of the LPC programming language.

Lars Pensjö of Sweden is the original author of the LPMud MUD engine and the LPC programming language, and is one of the founders of Genesis LPMud, notable for their part in the history of MMORPGs as well as the Pike programming language.

The Lima Mudlib is an LPC framework for building multi-user role playing games.

The Discworld mudlib is an LPC framework, or mudlib, originally written for the Discworld MUD.

Genesis was created as the first implementation of the LPC language, in which the developer ( commonly known as a wizard within the MUD ) is able to create objects by using a language similar to the C programming language.

The weighting filter W ( z ) is typically derived from the LPC filter by the use of bandwidth expansion:

However, one of the ways that IMC2 differs significantly from I3 is that it does not use so called mudmode connections, making it much easier to implement IMC2 on muds not written in LPC.

Helminiak is a Fellow of the American Association of Pastoral Counselors and is licensed as a Professional Counselor ( LPC ) in the state of Georgia.

Also known as liquor carbonis detergens ( LCD ), and liquor picis carbonis ( Latin: coal tar solution ) ( LPC ), it can be used in medicated shampoo, soap and ointment, as a treatment for dandruff and psoriasis, as well as being used to kill and repel head lice.

Other types of lossy compressors, such as the linear predictive coding ( LPC ) used with speech, are source-based coders.

* LPC – ( Light / Lamp Post Cache ) used in the description on where a cache may be hidden.

* SL – ( Skirt Lifter ) refers to the metal or plastic skirt at the base of a lightpole, and used in reference to LPC caches ( see LPC ).

LPC synthesis can be used to construct vocoders where musical instruments are used as excitation signal to the time-varying filter estimated from a singer's speech.

A 10th-order LPC was used in the popular 1980's Speak & Spell educational toy.

LPC predictors are used in Shorten, MPEG-4 ALS, FLAC, and other lossless audio codecs.

The TMS5100 used a 10th-order linear predictive coding ( LPC ) model and the electronic DSP logic.

* For messages longer than 256 bytes a shared memory section must be used to transfer data, which the ( A ) LPC service maps between the sending and receiving processes.

The programme can be seen as the equivalent of the Legal Practice Course ( LPC ) or the Bar Professional Training Course ( BPTC ) in England and Wales, which focuses heavily on practical issues, unlike a first degree in law.

The Win32 subsystem uses ( A ) LPC heavily for communication between client and the subsystem server ( CSRSS ).

In 1974 the first realtime two-way LPC packet speech communication was accomplished over the ARPANET at 3500 bit / s between Culler-Harrison and Lincoln Laboratories.

Integrates four USB ports, one ATA-66 UDMA controller, one Infrared communication port, one AC ' 97 controller, one SMBUS controller, one LPC port, as well as GPIO, Power Management, and legacy functional blocks.

The Local Procedure Call ( LPC, often also referred to as Lightweight Procedure Call or Local Inter-Process Communication ) is an internal, undocumented inter-process communication facility provided by the Microsoft Windows NT kernel for lightweight IPC between processes on the same computer.

As of Windows Vista, LPC has been rewritten as Advanced Local Procedure Call ( ALPC ) in order to provide a high-speed scalable communication mechanism required to efficiently implement User-Mode Driver Framework, whose user-mode parts require an efficient communication channel with UMDF's components in the executive.

The implementation of remote OLE and DCOM in many cases uses ( A ) LPC for local communication as well.

In 1976 the first LPC conference took place over the ARPANET using the Network Voice Protocol, between Culler-Harrison, ISI, SRI, and LL at 3500 bit / s.

( A ) LPC supports the following three modes of message exchange between the server and client:
