The Audio Random Access (ARA for short) interface allows plug-ins and DAWS to integrate much more thoroughly with each other. ARA allows plug-ins to:


  • Have direct access to the DAW's audio data. This means that a plug-in can read audio at rates much faster than real-time.
  • Read the names of the audio regions. Plug-ins will be able to display the correct name of each region, making it much easier for users to associate audio in a plug-in to the audio in the DAW.
  • Read the timing information of each region of audio directly. Plug-ins will automatically know the starting time of each region within a track


From version 5.97 of Reaper, there is a new, more versatile way of processing audio in Revoice Pro. Revoice Pro supports the new ARA 2 standard that allows a better and much faster exchange of information between DAWS and plug-ins.


When working with Revoice Pro and Reaper, ARA has the following advantages:


  • Immediate transfer of audio between the DAW and Revoice Pro.
  • Keeps the names and timings of all linked audio items. 
  • Revoice Pro remains synchronised with all the linked audio items. For example,  if you change the starting time  of an audio item in Reaper, the corresponding audio region in Revoice Pro will move to the new starting time.
  • Linking the output of any process in Revoice Pro to an audio item  allows immediate replay in Reaper of Revoice Pro's processing.
  • Load and saving of projects allows subsequent editing of previous work.
