ARA (Audio Random Access) is an API created by Celemony and PreSonus to enable a new class of audio plug-ins that are not used in realtime effect slots, but instead are tied into the arrangement of the DAW.
It is designed for plug-ins such as Melodyne which intrinsically need to evaluate the audio material in its entirety, not sliced into small realtime buffers. In addition to providing random access to the audio samples, ARA enables bi-directional communication about musical properties such as tempo maps, time and key signatures, or chord progressions of both the original audio material and the playback context.
Rather than doing a detailed dive into the API, the talk will focus on several core concepts of ARA that have a profound impact on the design of your code. It strives to give you a better idea about both the features and workflows that users will expect from ARA products, and the costs and liabilities involved. It will enable you to make an educated decision about whether or not ARA is the right tool for your product, and get you started with the right mindset should you go for it.
If you’re interested in this talk, please also note the follow-up session at 4:20 which will demonstrate how ARA is integrated into JUCE.
