He or she is present in the recording studio or at the location recording and works directly with the artist and engineer. The producer makes creative and aesthetic decisions that realize both
249-443: A solution for each instance. Instances are questions that we can ask, and solutions are desired answers to these questions. Theoretical computer science seeks to understand which computational problems can be solved by using a computer ( computability theory ) and how efficiently ( computational complexity theory ). Traditionally, it is said that a problem can be solved by using a computer if we can design an algorithm that produces
332-423: A broad project, the creation of a popular music recording may be split across three specialists: the executive producer , who oversees business partnerships and financing; the vocal producer or vocal arranger, who aids vocal performance via expert critique and coaching of vocal technique, and the record producer or music producer, who, often called simply the producer, directs the overall creative process of recording
415-474: A common goal for their work. The terms " concurrent computing ", " parallel computing ", and "distributed computing" have much overlap, and no clear distinction exists between them. The same system may be characterized both as "parallel" and "distributed"; the processors in a typical distributed system run concurrently in parallel. Parallel computing may be seen as a particularly tightly coupled form of distributed computing, and distributed computing may be seen as
498-520: A correct solution for any given instance. Such an algorithm can be implemented as a computer program that runs on a general-purpose computer: the program reads a problem instance from input , performs some computation, and produces the solution as output . Formalisms such as random-access machines or universal Turing machines can be used as abstract models of a sequential general-purpose computer executing such an algorithm. The field of concurrent and distributed computing studies similar questions in
581-471: A cylinder. By the 1930s, a gramophone etched it laterally across a disc. Constrained in tonal range, whether bass or treble, and in dynamic range , records made a grand, concert piano sound like a small, upright piano, and maximal duration was four and a half minutes. Selections and performance were often altered accordingly, and playing this disc—the wax master—destroyed it. The finality often caused anxiety that restrained performance to prevent error. In

The class NC can be defined equally well by using the PRAM formalism or Boolean circuits—PRAM machines can simulate Boolean circuits efficiently and vice versa. In the analysis of distributed algorithms, more attention is usually paid on communication operations than computational steps. Perhaps
747-621: A demo content DVD. On December 8, 2011, it was announced that the boxed version of Logic Studio suite would be discontinued. Instead, Logic Pro and Mainstage would be sold separately on the Mac App Store . Soundtrack Pro was discontinued as part of the move. The Apple Loops Utility software is a small companion utility to Soundtrack Pro , GarageBand , Logic Express , and Logic Pro , all made by Apple Inc. Apple Loops Utility allows users to create loops of audio that can be time-stretched . Audio files converted to "Apple Loops" via

The second version, MainStage 2, was released on July 23, 2009, along with updated releases of many of the other applications in the Logic Studio package. Soundtrack Pro is a music composing and audio editing application made by Apple Inc. , which includes a collection of just over 5000 royalty free professional instrument loops and sound effects. The program also allows multitrack projects to be exported directly with Compressor settings. WaveBurner can be used for assembling, mastering, and burning audio CDs . Audio CDs created with WaveBurner can be played back on any audio CD player, and can be used as premasters to produce CDs in large numbers for possible distribution. WaveBurner has several notable features: According to Apple, one needs to meet

During the decade, A&R executives increasingly directed songs' sonic signatures, although many still simply teamed singers with musicians, while yet others exercised virtually no creative influence. The term record producer in its current meaning—the creative director of song production—appearing in a 1953 issue of Billboard magazine, became widespread in

Nevertheless, it is possible to roughly classify concurrent systems as "parallel" or "distributed" using the following criteria: The figure on the right illustrates the difference between distributed and parallel systems. Figure (a) is a schematic view of a typical distributed system; the system is represented as a network topology in which each node

While there is no single definition of a distributed system, the following defining properties are commonly used as: A distributed system may have a common goal, such as solving a large computational problem; the user then perceives the collection of autonomous processors as
1162-516: A musical element while playing a previously recorded record, Les Paul developed a recording technique called "sound on sound". By this, the final recording could be built piece by piece and tailored, effecting an editing process. In one case, Paul produced a song via 500 recorded discs. But, besides the tedium of this process, it serially degraded the sound quality of previously recorded elements, rerecorded as ambient sound. Yet in 1948, Paul adopted tape recording, enabling true multitrack recording by
1245-542: A new technique, " overdubbing ". To enable overdubbing, Paul revised the tape recorder itself by adding a second playback head, and terming it the preview head . Joining the preexisting recording head, erase head, and playback head, the preview head allows the artist to hear the extant recording over headphones playing it in synchrony, "in sync", with the present performance being recorded alone on an isolated track. This isolation of multiple tracks enables countless mixing possibilities. Producers began recording initially only
1328-424: A problem is divided into many tasks, each of which is solved by one or more computers, which communicate with each other via message passing. The word distributed in terms such as "distributed system", "distributed programming", and " distributed algorithm " originally referred to computer networks where individual computers were physically distributed within some geographical area. The terms are nowadays used in
1411-654: A schematic architecture allowing for live environment relay. This enables distributed computing functions both within and beyond the parameters of a networked database. Reasons for using distributed systems and distributed computing may include: Examples of distributed systems and applications of distributed computing include the following: According to Reactive Manifesto, reactive distributed systems are responsive, resilient, elastic and message-driven. Subsequently, Reactive systems are more flexible, loosely-coupled and scalable. To make your systems reactive, you are advised to implement Reactive Principles. Reactive Principles are
1494-405: A sequential general-purpose computer? The discussion below focuses on the case of multiple computers, although many of the issues are the same for concurrent processes running on a single computer. Three viewpoints are commonly used: In the case of distributed algorithms, computational problems are typically related to graphs. Often the graph that describes the structure of the computer network
1577-457: A set of principles and patterns which help to make your cloud native application as well as edge native applications more reactive. Many tasks that we would like to automate by using a computer are of question–answer type: we would like to ask a question and the computer should produce an answer. In theoretical computer science , such tasks are called computational problems . Formally, a computational problem consists of instances together with

Actually, it says neither "A&R man" nor even "A&R", an initialism perhaps coined by Billboard magazine in 1946, and entering wide use in the late 1940s. In the 1920s and 1930s, A&R executives, like Ben Selvin at Columbia Records , Nathaniel Shilkret at Victor Records, and Bob Haring at Brunswick Records became
1743-695: A token ring network in which the token has been lost. Coordinator election algorithms are designed to be economical in terms of total bytes transmitted, and time. The algorithm suggested by Gallager, Humblet, and Spira for general undirected graphs has had a strong impact on the design of distributed algorithms in general, and won the Dijkstra Prize for an influential paper in distributed computing. Many other algorithms were suggested for different kinds of network graphs , such as undirected rings, unidirectional rings, complete graphs, grids, directed Euler graphs, and others. A general method that decouples

Alternatively, each computer may have its own user with individual needs, and the purpose of the distributed system is to coordinate the use of shared resources or provide communication services to the users. Other typical properties of distributed systems include the following: Here are common architectural patterns used for distributed computing: Distributed systems are groups of networked computers which share

Ultimately, the reasons are multiple and not fully clear, although prominently proposed factors include types of sexism and scarcity of female role models in the profession. Women producers known for producing records not their own include Sonia Pottinger, Sylvia Robinson and Carla Olson. In January 2018, a research team led by Stacy L. Smith, founder and director of

Different fields might take the following approaches: While the field of parallel algorithms has a different focus than the field of distributed algorithms, there is much interaction between the two fields. For example, the Cole–Vishkin algorithm for graph coloring
2075-416: Is a computer and each line connecting the nodes is a communication link. Figure (b) shows the same distributed system in more detail: each computer has its own local memory, and information can be exchanged only by passing messages from one node to another by using the available communication links. Figure (c) shows a parallel system in which each processor has a direct access to a shared memory. The situation

Many distributed algorithms are known with the running time much smaller than D rounds, and understanding which problems can be solved by such algorithms is one of the central research questions of the field. Typically an algorithm which solves a problem in polylogarithmic time in the network size is considered efficient in this model. Another commonly used measure
2324-581: Is further complicated by the traditional uses of the terms parallel and distributed algorithm that do not quite match the above definitions of parallel and distributed systems (see below for more detailed discussion). Nevertheless, as a rule of thumb, high-performance parallel computation in a shared-memory multiprocessor uses parallel algorithms while the coordination of a large-scale distributed system uses distributed algorithms. The use of concurrent processes which communicate through message-passing has its roots in operating system architectures studied in

In digital recording, however, a recent advancement, 32-bit float , enables DAWs to undo clipping. Still, some criticize digital instruments and workflows for excess automation, allegedly impairing creative or sonic control. In any case, as production technology has drastically changed, so have
2490-478: Is necessary to interconnect processes running on those CPUs with some sort of communication system . Whether these CPUs share resources or not determines a first distinction between three types of architecture: Distributed programming typically falls into one of several basic architectures: client–server , three-tier , n -tier , or peer-to-peer ; or categories: loose coupling , or tight coupling . Another basic aspect of distributed computing architecture

It is distinct from the role of an executive producer , who is mostly involved in the recording project on an administrative level, and from the audio engineer who operates the recording technology. Varying by project, the producer may or may not choose all of the artists. If employing only synthesized or sampled instrumentation,

Distributed processing The components of a distributed system communicate and coordinate their actions by passing messages to one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming
2739-492: Is the method of communicating and coordinating work among concurrent processes. Through various message passing protocols, processes may communicate directly with one another, typically in a main/sub relationship. Alternatively, a "database-centric" architecture can enable distributed computing to be done without any form of direct inter-process communication , by utilizing a shared database . Database-centric architecture in particular provides relational processing analytics in
2822-410: Is the number of synchronous communication rounds required to complete the task. This complexity measure is closely related to the diameter of the network. Let D be the diameter of the network. On the one hand, any computable problem can be solved trivially in a synchronous distributed system in approximately 2 D communication rounds: simply gather all information in one location ( D rounds), solve
2905-511: Is the total number of bits transmitted in the network (cf. communication complexity ). The features of this concept are typically captured with the CONGEST(B) model, which is similarly defined as the LOCAL model, but where single messages can only contain B bits.

Also that month, Billboard magazine queried, "Where are all the female music producers?" Upon the Annenberg Inclusion Initiative's second annual report, released in February 2019, its department at USC reported, "2018 saw an outcry from artists, executives and other music industry professionals over

Examples of distributed systems vary from SOA-based systems to microservices to massively multiplayer online games to peer-to-peer applications . Distributed systems cost significantly more than monolithic architectures, primarily due to increased needs for additional hardware, servers, gateways, firewalls, new subnets, proxies, and so on.

Across the 1960s, popular music increasingly switched from acoustic instruments, like piano, upright bass , acoustic guitar , and brass instruments , to electronic instruments, like electric guitars , keyboards , and synthesizers , employing instrument amplifiers and speakers. These could mimic acoustic instruments or create utterly new sounds. Soon, by combining

For example, if each node has unique and comparable identities, then the nodes can compare their identities, and decide that the node with the highest identity is the coordinator. The definition of this problem is often attributed to LeLann, who formalized it as a method to create a new token in
3569-462: The 1940s, during World War II, the Germans refined audio recording onto magnetic tape—uncapping recording duration and allowing immediate playback, rerecording, and editing—a technology that premised emergence of record producers in their current roles. Early in the recording industry, a record was attained by simply having all of the artists perform together live in one take. In 1945, by recording

Advances in recording technology, especially the 1940s advent of tape recording —which Les Paul promptly innovated further to develop multitrack recording —and the 1950s rise of electronic instruments, turned record production into a specialty. In popular music, then, producers like George Martin , Phil Spector and Brian Eno led its evolution into its present use of elaborate techniques and unrealistic sounds, creating songs impossible to originate live. After

A&R managers might still be creative directors, like William "Mickey" Stevenson , hired by Berry Gordy , at the Motown record label. In 1947, the American market gained audio recording onto magnetic tape. At the record industry's 1880s dawn, rather, recording was done by phonograph , etching the sonic waveform vertically into

ARPANET , one of the predecessors of the Internet , was introduced in the late 1960s, and ARPANET e-mail was invented in the early 1970s. E-mail became the most successful application of ARPANET, and it is probably the earliest example of a large-scale distributed application . In addition to ARPANET (and its successor,

By now, DAWs, or digital audio workstations , like Logic Pro , Pro Tools and Studio One , turn an ordinary computer into a production console, whereby a solitary novice can become a skilled producer in a thrifty home studio. In the 2010s, efforts began to increase the prevalence of producers and engineers who are women, heavily outnumbered by men and prominently accoladed only in classical music. As

Multiple files can be tagged at the same time, a process known as batch tagging. Apple Loops Utility can read both AIFF and WAV file formats , but it will convert the latter to AIFF when saved with tagging information. Compressor is a video and audio media compression and encoding application for use with Final Cut Studio and Logic Studio on Mac OS X . It can be used with Qmaster for clustering . Compressor

Yet especially influential was the Beach Boys, whose band leader Brian Wilson took over from his father Murry within a couple of years after the band's commercial breakthrough. By 1964, Wilson had taken Spector's techniques to unseen sophistication. Wilson alone produced all Beach Boys recordings between 1963 and 1967. Using multiple studios and multiple attempts of instrumental and vocal tracks, Wilson selected

If the network is fast enough (i.e. gigabit Ethernet ) this can work in near-real time, depending on buffer settings and CPU loads. This allows users to combine the power of several Mac computers to process Logic Pro’s built-in software instruments and plug-ins, and 3rd party processing plug-ins. MainStage's primary purpose

However, there are also problems where the system is required not to stop, including the dining philosophers problem and other similar mutual exclusion problems. In these problems, the distributed system is supposed to continuously coordinate the use of shared resources so that no conflicts or deadlocks occur. There are also fundamental challenges that are unique to distributed computing, for example those related to fault-tolerance . Examples of related problems include consensus problems , Byzantine fault tolerance , and self-stabilisation . Much research

During each communication round , all nodes in parallel (1) receive the latest messages from their neighbours, (2) perform arbitrary local computation, and (3) send new messages to their neighbors. In such systems, a central complexity measure
6308-431: The song in its final mix. The producer's roles can include gathering ideas, composing music, choosing session musicians , proposing changes to song arrangements, coaching the performers, controlling sessions, supervising the audio mixing , and, in some cases, supervising the audio mastering . A producer may give creative control to the artists themselves, taking a supervisory or advisory role instead. As to qualifying for
6391-432: The task is begun, all network nodes are either unaware which node will serve as the "coordinator" (or leader) of the task, or unable to communicate with the current coordinator. After a coordinator election algorithm has been run, however, each node throughout the network recognizes a particular, unique node as the task coordinator. The network nodes communicate among themselves in order to decide which of them will get into
6474-419: The technical engineering of the recording, and coordinating the production team and process. The producer's involvement in a musical project can vary in depth and scope. Sometimes in popular genres the producer may create the recording's entire sound and structure. However, in classical music recording, for example, the producer serves as more of a liaison between the conductor and the engineering team. The role
6557-481: The vast majority have been men. Early in the 2010s, asked for insights that she herself had gleaned as a woman who has specialized successfully in the industry, Wendy Page remarked, "The difficulties are usually very short-lived. Once people realize that you can do your job, sexism tends to lower its ugly head." Still, when tasked to explain her profession's sex disparity, Page partly reasoned that record labels, dominated by men, have been, she said, "mistrustful of giving
6640-658: Was an early female record producer, having produced both of her Ivor Novello award-winning songs. Across the decades, many female artists have produced their own music. For instance, artists Kate Bush , Madonna , Mariah Carey , Janet Jackson , Beyoncé (even that of Destiny's Child and the Carters ), Lana Del Rey , Taylor Swift , and Lorde have produced or coproduced and Ariana Grande who produces and arranges her vocals as well as being an audio engineer. Still among specialists, despite some prominent women, including Missy Elliott in hip hop and Sylvia Massy in rock,
6723-540: Was first held in Ottawa in 1985 as the International Workshop on Distributed Algorithms on Graphs. Various hardware and software architectures are used for distributed computing. At a lower level, it is necessary to interconnect multiple CPUs with some sort of network, regardless of whether that network is printed onto a circuit board or made up of loosely coupled devices and cables. At a higher level, it
6806-455: Was her fifth. Yet in nonclassical, no woman has won Producer of the Year , awarded since 1975 and only one even nominated for a record not her own, Linda Perry. After Lauren Christy 's 2004 nomination, Linda Perry 's 2019 nomination was the next for a woman. On why no woman had ever won it, Perry commented, "I just don't think there are that many women interested." In the U.K., Lynsey de Paul
6889-423: Was originally presented as a parallel algorithm, but the same technique can also be used directly as a distributed algorithm. Moreover, a parallel algorithm can be implemented either in a parallel system (using shared memory) or in a distributed system (using message passing). The traditional boundary between parallel and distributed algorithms (choose a suitable network vs. run in any given network) does not lie in
