Celemony Software has announced “ARA Audio Random Access” – an extension for existing audio plug-in interfaces designed to expand the communication between plug-in and DAW, affording the plug-in musical access to the audio data.

Developed by Celemony in collaboration with Presonus, ARA presently connects the Presonus DAW Studio One 2, shipping this fall, with the current Versions 1.3 of Melodyne. Other manufacturers and products will follow.


Here is what Celemony explains:

"The plug-in interfaces used today – such as VST, AU and RTAS – still work essentially the way analog mixers did in the past: a plug-in only receives audio data from the DAW track at the moment of playback, and therefore knows nothing about the entire track – and nothing either, therefore, of the musical context. For reverb, echo and EQ, this view through a real-time keyhole may be good enough, but not for plug-ins like Melodyne that need an overview of the entire clip for the analysis of the musical context and the editing of notes, rhythms and tempo. Previously, a time-consuming transfer of the audio file to the plug-in was required, but with ARA things are now far simpler:


As an extension of the existing plug-in interfaces, ARA opens an additional channel of communication through which the DAW and plug-in can exchange information about the audio file, tempo, pitch, rhythm and much more, which is designed to allow them to work more closely. The plug-in is closer to what is happening in the DAW; the DAW, for its part, is able to integrate the plug-in as though it were part of the DAW.


An example of the new workflow with ARA is the interaction between Presonus Studio One 2 and Melodyne. With ARA, Melodyne is integrated into Studio One and serves there as an alternative to the normal waveform editor: audio segments are opened directly in Melodyne and follow automatically when moved and copied as well as changed in tempo or time signature. Studio One, for its part, uses Melodyne for time stretching and to derive information about the musical content, i.e. for Audio-to-MIDI via drag-and-drop and for the evaluation of Melodyne’s tempo recognition."
