Latency: Myths and Facts. Part 3: A look at a quantitative study.

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!

Did you vote for the last whatever election and you are proud of it? Most likely you just back-stabbed democracy (whatever you ended up voting for)

What wait? Wasn’t this blog about Linux/Audio stuff? Why this politics based topic? And how an earth the emblem of democracy, the act of voting, can be in any way not-democratic?

Well, for the first questions, as previously in the past, I feel sometimes that I want to write about something else.

As for the last question…

The Linux Audio Anatomy

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!

Rambling about stuff: intelligence and computers

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.

But let’s try to put some order into this ramble.

A look at Ubuntu Studio 16.04

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!

The Best Linux Audio Distro!

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!

Entroware Apollo VS Mac Book Air

ArchMac
Screenshots of the machines. Damn Fedora’s wallpapers are pretty!

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!

Audio Linux OSes Reviews: ArchBang Linux

ArchBang Linux Logo.

I have been using ArchBang Linux for a while now, almost 3 years. So, I am able to give my impressions of its audio capabilities and workflow. This is my first review, so I have not developed a scheme yet (a part for some definitions)… but I think it will form by itself the more I go on. So, let’s dig into ArchBang!

Audio stability of a computer system

Well, suppose we have a computer of any kind, a sound card and an operating system installed and ready to go. Nice, we think we are ready to make music then! However, this may not always be the case. In fact, the system (in the following I will refer to system as the union of a computer, with a sound card, and an operating system configured for audio) may not be able to perform stably enough from the audio point of view. In simple words stability is the capability of the system to run over a prolonged period of time without encountering issues. Imagine we are trying to record a song. To be able to do that not only the system will have to respect our requirements on latency (if any) and sampling variables, but it will have to do it for a long time span, hopefully way longer than the time over which we need good audio performances, so that sample errors, losses, pops, clicks, xruns and crashes don’t ruin everything, wasting our time. We may intuitively define the audio stability (just stability in the following) of a system as the capability to perform audio tasks without encountering issues over time. For sure, we prefer a system as stable as it can get.

But how to define audio stability?

Contents in preparation

Ok, so… this blog will be slowly filled with something. This something will be some brainstorming stuff from science/audio/music topics. However, I am planning to go off-topic if something is interesting for me. More in deep, I’d like to publish content about acoustics, electronics and open source, all linked to music. I also wish to publish reviews of Linux distros and software, focusing on the audio capabilities and workflow. I would like to cover also hidden non-Linux operative systems I found interesting, as well as hardware reviews. I am planning to post electronics tips and maybe tutorials… there is something in the back of my head… I just have to find time and inspiration!

Still testing stuff in the meanwhile… here the three dimensional wave equation… just to test the \LaTeX interpreter…

\nabla^{2}p=\frac{1}{c^{2}}\frac{\partial^{2}p}{\partial t^{2}}
