Logic Express
Logic Express was a "light" version of Logic Pro, a MIDI sequencer and digital audio workstation software application maintained by Apple that runs on the Mac OS X platform. It was announced on January 15, 2004, for release in March 2004. Logic Pro and Express shared most functionality and the same interface. Logic Express was limited to two-channel stereo mixdown, while Logic Pro can handle multichannel surround sound; Logic Express also lacked support for TDM/DAE systems, high-end control surfaces and Distributed Audio Processing. Both could handle up to 255 audio tracks, depending on system performance ( CPU, hard disk throughput and seek time). Logic Express 8 came with 36 software instruments and 73 effect plug-ins, including almost all of those in the Logic Pro Package. Those that it didn't include are Sculpture, a physical modelling synthesiser; the "vintage" instruments (the EVB3 tonewheel organ, the EVD6 Clavinet and the EVP88 Electric Piano), however a cut-down version ...

Audio Control Surface
In the domain of digital audio, a control surface is a human interface device (HID) which allows the user to control a digital audio workstation or other digital audio application. Generally, a control surface will contain one or more controls that can be assigned to parameters in the software, allowing tactile control of the software. As digital audio software is complex and can play any number of functions in the audio chain, control surfaces can be used to control many aspects of music production, including virtual instruments, samplers, signal processors, mixers, DJ software, and music sequencers. Since control surfaces are designed to perform different functions, they vary widely in size, shape and number and type of controls. A basic control surface for mixing resembles a traditional analogue mixing console, featuring faders, knobs (rotary encoders), and buttons that can be assigned to parameters in the software. Other control surfaces are designed to give a musician control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Core Audio
Core Audio is a low-level API for dealing with sound in Apple's macOS and iOS operating systems. It includes an implementation of the cross-platform OpenAL. Apple's Core Audio documentation states that "in creating this new architecture on Mac OS X, Apple's objective in the audio space has been twofold. The primary goal is to deliver a high-quality, superior audio experience for Macintosh users. The second objective reflects a shift in emphasis from developers having to establish their own audio and MIDI protocols in their applications to Apple moving ahead to assume responsibility for these services on the Macintosh platform." History It was introduced in Mac OS X 10.0 (Cheetah). See also * Audio Units * PulseAudio PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, various BSD distributions such as FreeBSD and OpenBSD, macOS, as well as Illumos distributions and the Solaris operat ... Re ...

Audio Units
Audio Units (AU) are a system-level plug-in architecture provided by Core Audio in Apple's macOS and iOS operating systems. Audio Units are a set of application programming interface (API) services provided by the operating system to generate, process, receive, or otherwise manipulate streams of audio in near-real-time with minimal latency. It may be thought of as Apple's architectural equivalent to another popular plug-in format, Steinberg's Virtual Studio Technology (VST). Because of the many similarities between Audio Units and VST, several commercial and free wrapping technologies are available (e.gSymbiosisand FXpansionbr>VST-AU Adapter. Celemony Software and PreSonus have also developed the Audio Random Access (ARA) extension, which works for both AU and VST, allowing greater integration between the plug-ins and DAW software. Use Audio Units allows sound file audio time stretching and pitch scaling (e.g., timestretch), sample rate conversion, and streaming over a Loca ...

Logic Control
Logic Control is a control surface originally designed by Emagic in cooperation with Mackie. History Logic Control was designed by Emagic as a dedicated control surface for their Logic digital audio workstation software. It was manufactured by Mackie, but distributed by Emagic. About 6 months later, Mackie introduced a physically identical product called "Mackie Control" which included support for most major DAW applications, but not Logic. The Emagic Logic Control was still available and would only work with Logic. Later, Mackie Control's firmware was revised to include compatibility with Logic, combining together Mackie Control, Logic Control and Human User Interface (HUI) into a single protocol. As a result, the name was changed to "Mackie Control Universal" (MCU). Out of the box, MCU included Lexan overlays with different button legends to support control of other DAWs such as Pro Tools and Cubase. Description Logic Control (and now MCU) allows control of almost all Logic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Musician John Mayer assisted with its demonstration. It is par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seek Time
Higher performance in hard disk drives comes from devices which have better performance characteristics. These performance characteristics can be grouped into two categories: access time and data transfer time (or rate). Access time The ''access time'' or ''response time'' of a rotating drive is a measure of the time it takes before the drive can actually transfer data. The factors that control this time on a rotating drive are mostly related to the mechanical nature of the rotating disks and moving heads. It is composed of a few independently measurable elements that are added together to get a single value when evaluating the performance of a storage device. The access time can vary significantly, so it is typically provided by manufacturers or measured in benchmarks as an average. The key components that are typically added together to obtain the access time are: * Seek time * Rotational latency * Command processing time * Settle time Seek time With rotating drives, the ...

Throughput
Network throughput (or just throughput, when in context) refers to the rate of message delivery over a communication channel, such as Ethernet or packet radio, in a communication network. The data that these messages contain may be delivered over physical or logical links, or through network nodes. Throughput is usually measured in bits per second (bit/s or bps), and sometimes in data packets per second (p/s or pps) or data packets per time slot. The system throughput or aggregate throughput is the sum of the data rates that are delivered to all terminals in a network. Throughput is essentially synonymous to digital bandwidth consumption; it can be determined numerically by applying the queueing theory, where the load in packets per time unit is denoted as the arrival rate (), and the drop in packets per unit time is denoted as the departure rate (). The throughput of a communication system may be affected by various factors, including the limitations of the underlying analog ...

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely on ...

Surround Sound
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three ''screen channels'' of sound that played from three loudspeakers (left, center, and right) located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction (at ground level) around the listener. The technique enhances the perception of sound spatialization by exploiting sound localization: a listener's ability to identify the location or origin of a detected sound in direction and distance. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers. Surround sound typically has a listener location ( sweet sp ...
