Audio Random Access (ARA2) support

Support for Audio Random Access v2, which is an extension for audio plug-ins allowing them to exchange a greater amount of audio information. This is necessary for the integrated use of many audio tools like Melodyne, Spectralayers, and Synchro Arts’ Vocalign and and Revoice Pro.

What problem(s) would this feature resolve?

Communication of DAW state to the plugin; including offline audio transfer, undo/redo, instant update when you move/cut/edit some audio.

How does this feature fit in Bitwig as a product?

Implementation in Bitwig would follow what today is an open specification impleemnted by many DAWs. ARA2 compatible plugins have their own UI and their functionality/processing is written back to the track in real time.

Celemony released the ARA SDK under an open source license on May 2021. This allows companies like Bitwig to implement the support to the ARA specification 2.0 without licensing costs.

Is there already an alternative way to achieve this on Bitwig?


Could it be implemented using Bitwig components or APIs, without Bitwig team’s support?


Could it be provided by a VST or something else reasonably integrated with Bitwig?


Are there other products that offer this feature?

Cakewalk by Bandlab, Studio 1, Acid Pro, Reaper, Logic Pro, Cubase, Nuendo, Pro Tools (2022.9).

You might want to add Acoustica | Digital Audio Editor to the list.

Acoustica 7 is the perfect solution for audio editing, podcast creation, mastering and audio restoration

This needs to happen. It’s not a smooth workflow needing to re transfer audio to melodyne if you need to make an edit in the arrangement or you want to mute a clip etc.
