LV2
LV2 (LADSPA Version 2) is a set of royalty-free open standards for plug-in (computing), plug-ins and matching host applications. It includes support for the audio synthesis, synthesis and digital signal processing, processing of digital audio and CV/gate, CV, events such as MIDI and Open Sound Control, OSC, and provides a free alternative to audio plug-in standards such as Virtual Studio Technology (VST) and Audio Units (AU). LV2 succeeds the more limited Linux Audio Developer's Simple Plugin API (LADSPA) standard and replaces the Disposable Soft Synth Interface (DSSI) plugin infrastructure ("LADSPA for instruments"), adding abilities such as MIDI capability, custom UIs, and a system allowing extensibility of the initial standard. Over twelve hundred plugins are now available in LV2 format. Notable plugins include Calf Studio Gear. Software that can host LV2 plugin "bundles" includes Ardour (software), ArdourIngen [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calf Studio Gear
Calf Studio Gear, often referred to as Calf Plugins, is a set of open source LV2 plugins for the Linux platform. The suite intends to be a complete set of plugins for audio mixing, virtual instruments and mastering. As of version 0.90.0 there are 47 plugins in the suite. History Calf Studio Gear development started in late 2007 when the LV2 plugin standard was in its infancy. Calf Studio Gear was one of the first projects to bring graphical audio plugins to Linux. The first versions up to 0.0.19 included support for LADSPA and DSSI as well which was dropped in December 2011. The project was initiated by Krzysztof Foltman. In 2009 Markus Schmidt became interested in development of the plugin suite due to his frustration with proprietary software. He has been a driving force behind the plugins ever since and has been responsible for the overall design of Calf Studio Gear, as well as being the brains behind the DSP of many of its plugins. Included plugins Calf Studio Gea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Qtractor was simply the hobby project of one developer. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Studio Technology
Virtual Studio Technology (VST) is an audio plug-in software interface that integrates software synthesizers and effects units into digital audio workstations. VST and similar technologies use digital signal processing to simulate traditional recording studio hardware in software. Thousands of plugins exist, both commercial and freeware, and many audio applications support VST under license from its creator, Steinberg. Overview VST plugins generally run within a digital audio workstation (DAW), to provide additional functionality, though a few standalone plugin hosts exist that support VST. Most VST plugins are either instruments (VSTi) or effects (VSTfx), although other categories exist—for example spectrum analyzers and various meters. VST plugins usually provide a custom graphical user interface that displays controls similar to physical switches and knobs on audio hardware. Some (often older) plugins rely on the host application for their user interface. VST instrume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audio Plug-in
An audio plug-in, in computer software, is a plug-in that can add or enhance audio-related functionality in a computer program. Such functionality may include digital signal processing or sound synthesis. Audio plug-ins usually provide their own user interface, which often contains GUI widgets that can be used to control and visualise the plug-in's audio parameters. Types There are three broad classes of audio plug-in: those which transform existing audio samples, those which generate new audio samples through sound synthesis and those which analyze existing audio samples. Although all plug-in types can technically perform audio analysis, only specific formats provide a mechanism for analysis data to be returned to the host. Instances The program used to dynamically load audio plug-ins is called a plug-in host. Example hosts include Bidule, Gig Performer, Mainstage, REAPER and Sonic Visualiser. Plug-ins can also be used to host other plug-ins. Communication between host ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FFmpeg
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects and standards compliance (SMPTE, ITU). FFmpeg also includes other tools: ffplay, a simple media player and ffprobe, a command-line tool to display media information. Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a Gstreamer-like filtergraph.

Turtle (syntax)
In computing, Terse RDF Triple Language (Turtle) is a syntax and file format for expressing data in the Resource Description Framework (RDF) data model. Turtle syntax is similar to that of SPARQL, an RDF query language. It is a common data format for storing RDF data, along with N-Triples, JSON-LD and RDF/XML. RDF represents information using semantic triples, which comprise a subject, predicate, and object. Each item in the triple is expressed as a Web URI. Turtle provides a way to group three URIs to make a triple, and provides ways to abbreviate such information, for example by factoring out common portions of URIs. For example, information about Huckleberry Finn could be expressed as: <http://example.org/person/Mark_Twain> <http://example.org/relation/author> <http://example.org/books/Huckleberry_Finn> . History Turtle was defined by Dave Beckett as a subset of Tim Berners-Lee and Dan Connolly's Notation3 (N3) language, and a superset of the minimal N- ...

Linux Audio Developer's Simple Plugin API
LADSPA is an acronym for Linux Audio Developer's Simple Plugin API. It is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under LGPL-2.1-or-later. It was originally designed for Linux through consensus on the Linux Audio Developers Mailing List, but works on a variety of other platforms. It is used in many free audio software projects and there is a wide range of LADSPA plug-ins available. LADSPA exists primarily as a header file written in the programming language C. There are many audio plugin standards and most major modern software synthesizers and sound editors support a variety. The best known standard is probably Steinberg's Virtual Studio Technology. LADSPA is unusual in that it attempts to provide only the "Greatest Common Divisor" of other standards. This means that its scope is limited, but it is simple and plugins written using it are easy to embed in many other programs. The standard ha ...

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 ove ...

Disposable Soft Synth Interface
Disposable Soft Synth Interface (DSSI) is a virtual instrument ( software synthesizer) plugin architecture for use by music sequencer applications. It was designed for applications running under Linux, although there is nothing specific to Linux in the interface itself. It is distributed under the terms of a combination of LGPL-2.1-or-later and some BSD licenses, all of which are free software licences. Features DSSI is sometimes described as ''Linux Audio Developer's Simple Plugin API'' ( LADSPA) for instruments. LADSPA is an audio effects plugin architecture for filters, reverbs and other sound processing software tools, whereas DSSI was designed specifically for instrument plugins that generate sound from note events. DSSI extends LADSPA by adding note event delivery, but it also adds predefined program selections and a method for plugins to provide their own user interfaces, both of which may also be used by effects plugins. This is partly because DSSI was intended to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
