It's now official, I'm going to New Zealand for work, so I'm going to be away for a couple of weeks. It's probably going to be very difficult to work on the software during those two weeks.
However, I'd like to make some progress, so instead of improving the SoundProcessor, and publish a new video, I will start to write the new project. I intend to publish the project by the end of the month. The software is now stable enough, even if there's still the sound processor to improve.
Apart from that, I ran the software on my Raspberry Pi 2 with Ubuntu MATE 15.10, it works pretty well. So far, it has been running on my laptop under Debian (Jessie, and Sid), Xubuntu (15.04, and 15.10), and on the Raspberry Pi 2 under Raspbian (Wheezy, and Jessie), and Ubuntu MATE (15.10). I think it's important to make sure that the software runs okay with different operating systems. So far, so good!
