In this episode about Open Source Acoustic Modelling we will look at how to make a simple Julia model of one of the simplest systems in acoustics, a rectangular room with rigid walls, assuming adiabatic wave propagation. Even if this system is among the simplest in acoustics, it is actually already very complicated. As such, we will focus only on the modes, one part of the problem, without attempting impulse response simulation or other fancy things like that, for now.
See this page for all the episodes in order of publication.

As part of my profession as an acoustician, I often make use of Open Source software. It might surprising to few that the Open Source ecosystem is actually filled with very good packages for this task. As a result, I decided to try to publish a little series of tutorials about the topic, and this would be its first post.
So let’s first have a look ad the most important numerical simulation programs and technical computing languages that can be used to simulate acoustics. There are many programs out of there, but I mainly made use of ElmerFEM. ElmerFEM will be the focus of the series then, and we will look at how to set up Ubuntu 18.04 to be our workstation!

So, I have been using a Focusrite Scarlett 2i4 for quite some time. I have now changed to another cheaper interface, and I though it was a good occasion to draw my conclusions on what I think about the Scarlett.
Overall, my opinions are mixed. There are good pros about this device, but also few significant cons.
Although the product I am reviewing is not current anymore (there is a new generation out there now) I think it might still be useful to have a look into this, as it can give some insight about what kind of products and functionality we can expect from Focusrite.

For new Linux users audio can be a shock. Many newbies that ask for support on forums have a perfectly working system, but are prompted to think otherwise by the not-really-straightforward way audio on Linux works. This post is an attempt to summarize and clarify how Linux audio works on a standard modern Linux installation.
So, let’s dig in!

It has been a while since the latest Ubuntu Studio 16.04 has been released. I couldn’t resist to make a live pen-drive with it and boot it on my Apollo. I also wanted to see how it performs with respect my Arch Linux. This is not going to be, however, a full review (like for ArchBang). The reason is that I did not install the system. I think that the only way to fairly compare OSes is to install them on the same hardware. I lack, sadly, a test computer. My Apollo is all I got and I must stay productive with it…
Anyway, lets have just a quick look at the features and let’s see if we can figure out what Ubuntu Studio 16.04 has to offer!

In the Linux ecosystem there are literally hundreds of distributions. According to DistroWatch, we have 277 actively developed distributions (the actual number is likely lager). Only few of them are “pro audio” distributions, but there is still plenty to choose from for people interested in doing music on Linux. During these last 10 years I have been hopping from a distribution to another. As such, I think it might be useful for you if I reveal which one is the Best Linux Audio Distro ever existed!

Many resources can be found online to guide through the process of proper Pro Audio Linux configuration. However, very often they are obscure, especially for beginners. I will then collect the most useful resources in this page so that they can be retrieved easily (and I don’t forget about their existence). I will categorize the resources based upon how much they are distro-specific.

A very simple way to probe the Linux ecosystem is by having a look at DistroWatch.com. If we go to the Search Distributions page and select “Multimedia” as Distribution category we will find only 10 active distributions. However, only few of them are developed with “pro audio first” in mind. Also, not all the distributions of this kind are on DistroWatch. For this reason, I will list here the distros I bumped into along these years. I did not try all of them (yet) but I will give my impressions for the ones I tried.

So, I did some test of my new Entroware Apollo and got some nice results. Running on GNOME 3, realtime kernel and nothing much more (not even by boosting CPUs) the system performances are already very good, although none of the stability definitions have been respected.
But let’s go with order.

I recently purchased an Apollo 1000 from Entroware, a young British company specialized in Linux computers. I had it with Ubuntu 15.04, not really my favorite Linux distro, but I needed a working Linux environment quickly to replace my old Presario CQ61, that seemed close to death (still alive and well though…). Only in the last days I have been able to install Arch Linux and do some audio configuration. The results are quite promising!
