Apart from working with the Linux/jack/ladsa and other digital signal processing tools, I've looked at cloud processing in general (I'm EE after all) but also specifically for music applications, starting a bit bottom up.
So, I've made use here of a free (actually free, though there's a need to connect a billing account) AWS "ec2" Linux node. That's Linux based on Red Hat Enterprise Linux, kernel (like on you Android phone/pad/TV) 4.14+, essentially running on a single (virtual) thread of a 2.5GHz Xeon processor in the Amazon server farm.
Because that single thread processor running this pro Linux is on for 24/7 a month for free, has significant internet access (don't pull out more than 16GigaByte/Mo though, or you'll have to pay) I thought I'd run some of my studio processing audio basics on it, to see what gives...
If you want to try, it's quite possible to execute the same install and make commands I did, thought it requires some work to get the basic jack processing tools running, by lack of a dedicated (real time) audio AMI, but like I said, this facility is free for anyone to try, I could give a short summary of making these tools on your own amazon cloud node as well, these jack/ladspa tools are going to cose a lot less than the available free storage space.
So I worked on getting jack (the main real time streaming virtual networked audio server tool) compiled and running on a "virtual" audio domain, meaning no actual soundcard in/out (obviously), and compiled among others the "jack-rack" tool, which allows a rack full of potentially multi-channel audio processing steps, based on any subset of the long standing LADPSA plugin sets of tools:
Now, I'm in the process of making audio file player and recorder for wav/flac/mp3 for this setup, and maybe I'll get my (web) server scripts from the mothballs to do something publicly automated with this all.
Any rate I'm going to do a simple and short video on this example, maybe someone has a request what type of processing I should look at ?
