Vinyl Emulation
A close-up of a time-coded vinyl record Vinyl emulation allows a DJ to physically manipulate the playback of digital audio files on a computer using turntables as an interface, thus preserving the hands-on control and feel of DJing with vinyl. This has the added advantage of using turntables to play back audio recordings not available in phonograph form. This method allows DJs to scratch, beatmatch, and perform other turntablism that would be impossible with a conventional keyboard-and-mouse computer interface or less tactile DJ controllers. A ''digital vinyl system'' (DVS) may include a special time-coded vinyl record or be purely software. Characteristics Vinyl emulation normally uses special vinyl records which are played on conventional turntables. The vinyl is a recording of analog audio signals often referred to as timecode. The turntables' audio output - the timecode recording - is routed into an analog-to-digital converter, or ADC. This ADC may be a multi-channel ...

Disk Jockey
A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience. Types of DJs include radio DJs (who host programs on music radio stations), club DJs (who work at nightclubs or music festivals), mobile DJs (who are hired to work at public and private events such as weddings, parties, or festivals), and turntablists (who use record players, usually turntables, to manipulate sounds on phonograph records). Originally, the "disc" in "disc jockey" referred to shellac and later vinyl records, but nowadays DJ is used as an all-encompassing term to also describe persons who mix music from other recording media such as cassettes, CDs or digital audio files on a CDJ, controller, or even a laptop. DJs may adopt the title "DJ" in front of their real names, adopted pseudonyms, or stage names. DJs commonly use audio equipment that can play at least two sources of recorded music simultaneously. This enables them to blend tracks together to cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beatmatching
Beatmatching or pitch cue is a DJ technique of pitch shifting or time stretching an upcoming track to match its tempo to that of the currently playing track, and to adjust them such that the beats (and, usually, the bars) are synchronized—e.g. the kicks and snares in two house records hit at the same time when both records are played simultaneously. Beatmatching is a component of beatmixing which employs beatmatching combined with equalization, attention to phrasing and track selection in an attempt to make a single mix that flows together and has a good structure. Beatmatching is a core technique for DJing electronic dance music, and it is standard practice in clubs to keep a constant beat throughout the night, even if DJs change in the middle. Technique The beatmatching technique consists of the following steps: # While a record is playing, start a second record playing, but only monitored through headphones, not being fed to the main PA system. Use gain (or ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screenshot
A screenshot (also known as screen capture or screen grab) is an analog or digital image that shows the contents of a computer display. A screenshot is created by a (film) camera shooting the screen or the operating system An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for ... or software running on the device powering the display. Screenshot techniques Digital techniques The first screenshots were created with the first interactive computers around 1960. Through the 1980s, computer operating systems did not universally have built-in functionality for capturing screenshots. Sometimes text-only screens could be dumped to a text file, but the result would only capture the content of the screen, not the appearance, nor were graphics screens preservable this way. Some systems had a BS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic Mixing
Harmonic mixing or key mixing (also referred to as mixing in key) is a DJ technique of matching the musical key of tracks in a DJ mix to avoid dissonance and create harmonious mixes or mashups. Tracks may be matched if they are in the same key, if their keys are relative, or if their keys are in a subdominant or dominant relationship with one another. The Camelot wheel is based on the circle of fifths and can be used for harmonic mixing. Modern DJ software (such as VirtualDJ, Serato, and Rekordbox) can use algorithms to determine a track's key. Mixed In Key is specialized software designed for more accurate key detection and is compatible with some other DJ software. Other methods to determine key include the use of AI or looking up tracks in an online database.https://www.musicradar.com/news/getsongkeycom-gives-you-essential-music-theory-information-about-more-than-6-million-songs Some DJ software and hardware can also pitch shift a track to change its key to one tha ...

Open Sound System
The Open Sound System (OSS) is an interface for making and capturing sound in Unix and Unix-like operating systems. It is based on standard Unix devices system calls (i.e. POSIX read, write, ioctl, etc.). The term also sometimes refers to the software in a Unix kernel that provides the OSS interface; it can be thought of as a device driver (or a collection of device drivers) for sound controller hardware. The goal of OSS is to allow the writing of sound-based applications that are agnostic of the underlying sound hardware. OSS was created by Hannu Savolainen and is distributed under four license options, three of which are free software licences, thus making OSS free software. API The API is designed to use the traditional Unix framework of open(), read(), write(), and ioctl(), via device files. For instance, the default device for sound input and output is /dev/dsp. Examples using the shell: cat /dev/random > /dev/dsp # plays white noise through the speaker c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DirectSound
DirectSound is a deprecated software component of the Microsoft DirectX library for the Windows operating system, superseded by XAudio2. It provides a low-latency interface to sound card drivers written for Windows 95 through Windows XP and can handle the mixing and recording of multiple audio streams. DirectSound was originally written for Microsoft by John Miles. Besides providing the essential service of passing audio data to the sound card, DirectSound provides other essential capabilities such as recording and mixing sound, adding effects to sound (e.g., reverb, echo, or flange), using hardware accelerated buffers (if the sound card supports hardware acceleration) in Windows 95 through XP, and positioning sounds in 3D space. DirectSound also provides a means to capture sounds from a microphone or other input and controlling capture effects during audio capture. After many years of development, today DirectSound is a mature API, and supplies many other useful capabilities, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WASAPI
Windows Vista (formerly codenamed Windows "Longhorn") has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system. In addition to the new user interface, security capabilities, and developer technologies, several major components of the core operating system were redesigned, most notably the audio, print, display, and networking subsystems; while the results of this work will be visible to software developers, end-users will only see what appear to be evolutionary changes in the user interface. As part of the redesign of the networking architecture, IPv6 has been incorporated into the operating system, and a number of performance improvements have been introduced, such as TCP window scale option, TCP window scaling. Prior versions of Windows typically needed third-party wireless networking software to work properly; this is no longer the case with Windows Vista, as it includes comprehensive wireless networking ...

Audio Stream Input/Output
Audio Stream Input/Output (ASIO) is a computer audio interface driver protocol for digital audio specified by Steinberg, providing high data throughput, synchronization, and low latency between a software application and a computer's audio interface or sound card. ASIO was initially released in 1997 in order to enable streaming of one or more audio streams from an (multi-input/output) audio interface to a software and vice versa with minimal latency and sample accurate synchronization of the audio streams. It allows the audio streams to use any sample rate and supports bit resolutions of 16, 24, 32 bit integer and 32 or 64 bit floating point. The release of ASIO 2.0 in 1999 brought further enhancements such as ASIO Direct Monitoring, where an audio signal is monitored directly from the audio interface with basically zero latency, and ASIO Positioning Protocol, used to sample accurately synchronize a computer to other digital machines such as ADAT recorder or also othe ...

Sound Card
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term ''sound card'' is also applied to external audio interfaces used for professional audio applications. Sound functionality can also be integrated into the motherboard, using components similar to those found on plug-in cards. The integrated sound system is often still referred to as a ''sound card''. Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector; previously they used a S/PDIF connection to the motherboard or sound card. Typical uses of sound cards or sound card functionality include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection. Sound cards are also used for computer-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Module File
Module file (MOD music, tracker music) is a family of music file formats originating from the MOD file format on Amiga systems used in the late 1980s. Those who produce these files (using the software called music trackers) and listen to them form the worldwide MOD scene, a part of the demoscene subculture. The mass interchange of "MOD music" or "tracker music" (music stored in module files created with trackers) evolved from early FIDO networks. Many websites host large numbers of these files, the most comprehensive of them being the Mod Archive. Nowadays, most module files, including ones in compressed form, are supported by most popular media players such as VLC, Foobar2000, Exaile and many others (mainly due to inclusion of common playback libraries such as libmodplug for gstreamer). Structure Module files store digitally recorded samples and several "patterns" or "pages" of music data in a form similar to that of a spreadsheet. These patterns contain note number ...

Advanced Audio Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was developed by Dolby, AT&T, Fraunhofer and Sony, originally as part of the MPEG-2 specification but later improved under MPEG-4.ISO (2006ISO/IEC 13818-7:2006 – Information technology — Generic coding of moving pictures and associated audio information — Part 7: Advanced Audio Coding (AAC), Retrieved on 2009-08-06ISO (2006, Retrieved on 2009-08-06 AAC was designed to be the successor of the MP3 format (MPEG-2 Audio Layer III) and generally achieves higher sound quality than MP3 at the same bit rate. AAC encoded audio files are typically packaged in an MP4 container most commonly using the filename extension .m4a. The basic profile of AAC (both MPEG-4 and MPEG-2) is called AAC-LC (''Low Complexity''). It is widely supported in the industry and has been adopted as the default or standard audio format on products including Apple's iTunes Store, Nintendo's Wii, DSi and ...
