In the previous posts about latency (Part 1 and Part 2) we informally talked about latency and its perception. We mostly made “rule of thumb” reasoning in order to arrive to some reasonable conclusion about latency, its perception and good latency thresholds.
In this post we will look instead at a scientific paper published on the topic: The Effects of Latency on Live Sound Monitoring by Michael Lester and Jon Boley. Perception of sound is a very counter-intuitive and complex phenomenon, it will be nice to see how our rule of thumb compares to a more appropriate scientific study of the matter. It is not uncommon, especially in this field, to see results completely different from what it was expected due to simple reasoning…
So let’s not loose any more time and let’s dig in!
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.
The most followed posts in this blog were the ones reviewing the Entroware Apollo laptop I purchased. The reason is that it is hard to find detailed information about Entroware models. I have been using the Apollo-1000 model for a little over a year. It is the only computer I have, so I use it everyday. I though that a report of how this laptop behaves after a year would conclude the review, giving to interested people a feeling of how this computer ages. So, here I am giving to you my impressions.
Yeah, this blog should be about audio related stuff. However, I think I will concede myself to ramble about some other topics I am interested in. In many times of my life I have been left wandering what is intelligence. It is that kind of question nobody really has an answer to. Many definitions of intelligence can be given really. Not long ago I stumbled across this article. I read it with deep interest and curiosity. To my surprise, I found that the article, although aiming to discredit the idea of the brain as a computer, reinforced a lot that idea in my mind.
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!
There has been some interested comment on my previous posts (here and here) about the Entroware Apollo. Recently I got a Mac Book Air from the company I work with. As such I though a comparison with a laptop with similar design would be useful for people considering to buy an Entroware. So let’s dig in the comparison!
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.
