Many see ARA2 as a game-changer, a revolutionary breakthrough in audio production. Support for ARA2 has become a highly desired feature in many DAWs, especially for users working with vocals, speech, sound design, and audio post-production.
Today, youโll learn what ARA2 is in audio production and why itโs so important in todayโs audio standards.
Letโs get started!
What is ARA2 in Audio Production?
Audio Random Access (ARA) is a plugin extension that provides real-time data sharing and faster communication between a digital audio workstation (DAW) and plugins than traditional formats like VST, AU, or AAX. ARA lets plugins instantly access complete audio files along with tempo, pitch and rhythm information, removing the need for manual audio transfers to make editing workflows easier.
The history of ARA began with the introduction of the first version in 2011. It was developed in collaboration with Celemony and PreSonus and is designed to speed up audio editing workflows, especially for pitch correction, noise reduction, and other precise audio adjustments, performed in real time and non-destructively.
PreSonus Studio One (now Fender Studio Pro) was among the first DAWs to support ARA plugins, and Melodyne was among the first ARA plugins. ARA revolutionized how we produce music and edit audio, and many major DAWs now support it.
Later, in 2018, ARA2 was announced, introducing a more comprehensive exchange of information between DAW and plugins, including chord tracking, simultaneous multi-track editing, and improved plugin-DAW synchronization and integration.
Today, ARA2 plugins are a standard in post-production workflows, particularly for editing vocals, pitch correction, time correction, and spectral editing.
How ARA2 Works
With ARA2, your plugins are not limited to real-time playback or bouncing tracks. An ARA2 plugin can analyze multiple tracks faster and process information on pitch, timing, tempo, and rhythm of an entire track immediately, which allows for faster and more precise editing, especially for pitch and time corrections, without the need to play in real time or bounce stems.
For many traditional plugins, audio had to be captured while the plugin played the track, and then you could begin editing. ARA2 eliminates unnecessary steps, allowing you to access all information in the tracks immediately.
ARA2 plugins are more tightly integrated with your DAW, making their controls feel like part of the DAWโs interface. However, this deep integration also means that each DAW handles ARA2 plugins differently.
Why is ARA2 Important?
ARA2 elevates audio-editing efficiency, enabling you to edit and process audio tracks in seconds rather than minutes. It interacts with and accesses audio data from multiple tracks in the DAW timeline rather than track by track, reducing extra steps and speeding up the editing process, improving efficiency and creative flexibility.
By having instant access to large amounts of data, including pitch, rhythm, chord, tempo, etc., for the whole project, instead of by track or by section, you're ready to manipulate audio for alignments, pitch correction, and noise reduction.
The main benefits include real-time processing, non-destructive editing, and greater efficiency, as you donโt need to wait for the plugin to collect all the information.
Which DAWs Support ARA2?
As more ARA2 plugins are developed, ARA2 support has become a necessity for every major DAW. In the following list, youโll find ARA2-compatible DAWs.
Samplitude
First on our list is Samplitude, a Windows-only DAW with unique features such as object-based workflow and Hybrid Audio Engine. It offers expanded ARA2 support, making ARA2 plugins compatible with Samplitudeโs docking system and exclusive freeze, and enabling them to be applied to multiple tracks and objects.
Studio One (now Fender Studio Pro)
Studio One, now rebranded as Fender Studio Pro, was one of the first DAWs to support ARA plugins. Studio One is a multi-platform DAW that offers a modern interface, intuitive workflows, and Fenderโs amps and effects.
Logic Pro
Logic Pro is a Mac-only DAW with ARA2 support. However, ARA2 is less integrated than with other DAWs, as a few ARA plugins run natively on M chips and require running Logic in Rosetta. Logic Proโs highlights include AI session players, an impressive sound library, virtual instruments, and effects, all in a sleek interface.
Pro Tools
Pro Tools is the industry standard DAW for recording, editing, and mixing audio projects. Itโs known for its steep learning curve, but it offers powerful tools for music creation and learning. Pro Tools workflow ensures you are learning the industry-standard DAW used in many professional studios. It features professional third-party software, effects, and ARA2 support.
Cubase
Cubase is a flexible DAW that can suit any music genre. It features a rich library of VST instruments, sounds, and plugins to produce music out of the box. It has ARA2 support to streamline your post-production process and offers several versions to suit different budgets and skill levels.
Reaper
Reaper is a lightweight, customizable DAW that has gained more followers in recent years due to its affordable price, which can be attractive to beginners. It offers professional features that rival those of other industry-standard DAWs on the list, such as multi-track and MIDI recording and editing, mixing and mastering tools, and support for third-party plugins, including ARA2.
Mixcraft
Acousticaโs Mixcraft is a beginner-friendly Windows DAW featuring third-party plugin support, ARA2 compatibility, a loop library, sample libraries, a vast library of effects and virtual instruments, MIDI editing, and AI stem separation. It is praised for its approachability and ease of learning.
Cakewalk Sonar
Cakewalk Sonar, which comes from the acclaimed Cakewalk by BandLab, is a Windows DAW with innovations, including AI assist, the Award-Winning Skylight interface, high-performance engine, a solid library with instruments and effects, and ARA2 support.
ARA2 enables seamless integration between DAWs and plugins that typically require real-time audio playback to capture audio data.
A traditional plugin works as follows: you load the plugin in a trackโs channel, then wait for it to collect the required information or play the track; often, you need to bounce before you can begin using the plugin.
With ARA2, you load the plugin and start using it with all audio information (the full track or clip) available instantly. No waiting for collecting audio data or additional steps.
Popular ARA2 Plugins:
Celemony Melodyne
Synchro Arts VocAlign and Revoice Pro
Steinbergโs SpectraLayers
Sound Radix Auto-Align
Final Words
In summary, ARA stands for Audio Random Access, a plugin extension that bridges a plugin and a DAW, enabling seamless, deep audio data exchange. It eliminates unnecessary steps in traditional plugins and greatly accelerates audio post-production workflows.
