What is the best way to route audio tracks out of Live and into another application during playback/performance?
Hi all. I'm trying to route 8 tracks of audio out of Live and into another application so I can process the audio data in realtime and create visualizations. For now I am trying to do this on the same computer, but ideally I'd like to have the option to send some of the audio samples in the buffer of each track out over a local area network as say, UDP packets.
I'm a pro/advanced user and write my own software so I'm not looking for the basics - I'm hoping other advanced users out there could shed some light on this.
If I could, I would send the 8 tracks I'm trying to process to 8 matching Sends (in Live) and keep the original 8 tracks going out to the master (and out to the speakers) and then route the Sends to a virtual audio cable type driver to be received in my application that will visualize the audio data.
My main problem thus far is that I can't access more than one sound device at a time which prevents the above solution from happening. If I use a virtual audio cable driver to route the tracks into an external application it works, but since it's virtual I can't actually send it t the speakers any more. I could potentially play back and mix the audio in my custom application but I have some mastering/finalizing chains on the master track in Live that I can't reproduce outside of Live.
I realize that under Mac OS (I could potentially go with either Windows or Mac OS depending what offers the best solution) you can create a virtual audio device comprised of several audio devices together masking as single device, which in theory would achieve the goal, but on the Ableton site it advises against this for performance for reasons of audio stream sync and stability (and yes this is intended for performance).
The other possibility I thought of would be to have two physical computers both with an outboard 8 in/8 out audio interface (one for audio running Live, and one for visualization running my custom graphics software) - and literally send the tracks out 8 hardware outputs on the Live machine and through physical cables into the 8 hardware inputs on the second computer. This isn't ideal because of the amount of equipment and cost involved.
The only other path I haven't explored, and honestly don't know much about, is Max for Live. Is it possible to get access to the samples in the audio buffers/streams of tracks in Live? And if so could I somehow liberate them and send them out to either A) another audio device (such as a virtual audio cable driver - and into my graphics app) or B) send the data as network packets? Does anyone have any experience with this? I understand I could use Max for Live to do visualizations most likely, but I am writing custom visualization software and my goal is to route it to my software and not dive into Max (at least at this juncture).
Has anyone tried anything like or does anyone have some creative thinking that I haven't thought of yet? Any help would be tremendously appreciated. Thanks!
