Audio Random Access (commonly abbreviated to ARA) is an extension for audio plug-in interfaces, such as AU, VST and RTAS, allowing them to exchange a greater amount of audio information with digital audio workstation (DAW) software. It was developed in a collaboration between Celemony Software and PreSonus.
ARA increases the amount of communication possible between DAW software and a plug-in, allowing them to exchange important information, such as audio data, tempo, pitch, and rhythm, for an entire song, rather than just at the moment of playback.
This increased amount of information exchange, and availability of data from other points in time, removes the need for audio material to be transferred to & from the plug-in, allowing that plug-in to be used as a more closely integrated part of the DAW's overall interface. [1]
ARA was developed as a joint effort between Celemony Software and PreSonus, driven by the desire to increase the level of integration between Celemony's Melodyne plug-in and the DAWs using it. [2] It was first published in October 2011 and released as part of PreSonus' Studio One DAW (version 2) and Melodyne (Editor, Assistant and Essential versions 1.3). [2]
Version 2 of ARA was announced during the NAMM Show in January 2018, introducing new features such as the simultaneous editing of multiple tracks, transfer of chord track information, and undo synchronization with the DAW. [3] [4] DAWs which use ARA version 2 are not automatically backwards compatible with plug-ins using version 1. [5] The first DAWs to support ARA version 2 were Logic Pro X (version 10.4, released in January 2018) [6] and Studio One (version 4, released in May 2018). [7]
To allow software manufacturers to support ARA, a Software Development Kit has been published by Celemony. [8] [9]

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.
A digital audio workstation is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.
Programming is a form of music production and performance using electronic devices and computer software, such as sequencers and workstations or hardware synthesizers, sampler and sequencers, to generate sounds of musical instruments. These musical sounds are created through the use of music coding languages. There are many music coding languages of varying complexity. Music programming is also frequently used in modern pop and rock music from various regions of the world, and sometimes in jazz and contemporary classical music. It gained popularity in the 1950s and has been emerging ever since.
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).
Acid Pro is a professional digital audio workstation (DAW) software program currently developed by Magix Software. It was originally called Acid pH1 and published by Sonic Foundry, later by Sony Creative Software as Acid Pro, and since spring 2018 by Magix as both Acid Pro and a simplified version, Acid Music Studio. Acid Pro 11 supports 64-bit architectures, and has MIDI, ASIO, VST, VST3, DirectX Audio, and 5.1 surround sound support.
Logic Pro is a proprietary digital audio workstation (DAW) and MIDI sequencer software application for the macOS platform developed by Apple Inc. It was originally created in the early 1990s as Notator Logic, or Logic, by German software developer C-Lab which later went by Emagic. Apple acquired Emagic in 2002 and renamed Logic to Logic Pro. It was the second most popular DAW – after Ableton Live – according to a survey conducted in 2015.
Sound Forge is a digital audio editing suite by Magix Software GmbH, which is aimed at the professional and semi-professional markets. There are two versions of Sound Forge: Sound Forge Pro 12 released in April 2018 and Sound Forge Audio Studio 13 released in January 2019. Both are well known digital audio editors and offer recording, audio editing, audio mastering and processing.
Pitch correction is an electronic effects unit or audio software that changes the intonation of an audio signal so that all pitches will be notes from the equally tempered system. Pitch correction devices do this without affecting other aspects of its sound. Pitch correction first detects the pitch of an audio signal, then calculates the desired change and modifies the audio signal accordingly. The widest use of pitch corrector devices is in Western popular music on vocal lines.
REAPER is a digital audio workstation and MIDI sequencer application created by Cockos. The current version is available for Microsoft Windows and macOS, as well as for Linux. REAPER acts as a host to most industry-standard plug-in formats and can import all commonly used media formats, including video. REAPER and its included plug-ins are available in 32-bit and 64-bit format.
Human User Interface Protocol is a proprietary MIDI communications protocol for interfacing between a hardware audio control surface and digital audio workstation (DAW) software. It was first created by Mackie and Digidesign in 1997 for use with Pro Tools, and is now part of the Mackie Control Universal (MCU) protocol.
In computer music and professional audio creation, a DirectX plugin is a software processing component that can be loaded as a plugin into host applications to allow real-time processing, audio effects, mixing audio or act as virtual synthesizers. DirectX plugins allow the replacement of traditional recording studio hardware and rack units used in professional studios with software-based counterparts that can be connected together in a modular way. This allows host manufacturers to focus on the conviviality and efficiency of their products while specialized manufacturers can focus on the digital signal processing aspect. For example, there are plugins for effects boxes, such as reverbs and delays, effects pedals, like guitar distortion, flange and chorus, and for mixing and mastering processors such as compressors, limiters, exciters, sub bass enhancers, stereo imagers and many more.
Notion, previously stylized as NOTION, is a computer software program for music composition and performance, created by NOTION Music of Greensboro, North Carolina. NOTION Music was acquired by PreSonus in 2013 which in turn was acquired by Fender Musical Instruments in 2021. Notion 6 is available on Microsoft Windows and macOS, and Notion Mobile is available for Windows, macOS, iOS, Android and Fire OS.
Celemony Software GmbH is a German musical software company that specializes in digital audio pitch correction software. It produces Melodyne, a popular audio pitch modification tool similar to Auto-Tune, although the program itself is a manual tuning software.
MAGIX Samplitude/ Sequoia is a computer program made by MAGIX for recording, editing, mixing, mastering and outputting audio. The first version was released in 1992 for the Amiga and three years later for Microsoft Windows. The latest versions of the software are Samplitude Pro X5, Samplitude Pro X5 Suite and Sequoia 16. Samplitude is an example of a digital audio workstation (DAW).
