Type Audio Plug-In Interface Extension

Audio Random Access (commonly abbreviated to ARA) is an extension for audio plug-in interfaces, such as AU, VST and RTAS. It is developed jointly by Celemony Software and PreSonus.[1]

ARA increases the amount of communication possible between digital audio workstation (DAW) software and a plug-in, allowing them to exchange key information, such as audio data, tempo, pitch, and rhythm, for an entire song, rather than just at the moment of playback. This removes the need for audio material to be transferred to & from the plug-in and allows that plug-in to be used as a more closely integrated part of the DAW's overall interface.[1]

History

ARA was developed as a joint effort between Celemony Software and PreSonus. It was first published in October 2011 and released as part of the Studio One DAW (version 2) and Melodyne Editor, Assistant and Essential (versions 1.3).[2]

Version 2 of ARA was announced during NAMM in January 2018, introducing new features such as 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 backwards compatible with plug-ins using version 1.[5] The first DAWs to support ARA version 2 were Logic Pro (version 10.4)[6] and Studio One (version 4)[7].

ARA Implementation

To allow software manufacturers to support ARA, a Software Development Kit has been published by Celemony.[8][9]
