Space Beards (Jakub Sawczuk) Mac OS
Back in 2015, I wrote a lengthy article regarding my technique to recording excellent training content. Over the past five years, I have learned quite a few new things about audio, which I wanted to share here.
In addition, Opstad led the development of Apple's FontSync utility, a feature in the Mac OS 9.x operating system for controlling font attributes such as kerning and spacing. Opstad holds six patents in type technology. In 2004, he joined Agfa Monotype. See what Samar Srivastava (amphiicreatives) has discovered on Pinterest, the world's biggest collection of ideas.

Audio Recording Setup
Before we get too far ahead, I wanted to start by sharing some details about my audio recording setup. Here’s what it looks like visually.
Microphone Positioning
The position of your microphone makes a huge difference in your recording quality. A good microphone will not make up for a poorly-placed microphone.
- Make sure the microphone is pointing towards your mouth. Cardioid microphones have a “front” and “sides,” so you’ll want to make sure you’re talking “into” the front of the microphone.
- Reduce distance between your mouth and the microphone. When I’m recording video training for software developers, I typically keep the microphone less than 4 inches away. This will vary depending on your specific setup, but less is generally better.
- Avoid placing the microphone directly in front of your mouth. If you talk directly into the microphone, you risk generating “pops” from harsh “t” and “p” sounds. For example, consider the word “paper” where each of the two “p” consonants generate a lot of wind. You can reduce the impact of pops by using a pop filter. My personal preference has been to eliminate a pop filter. They takes up space and force extra distance between you and the microphone.
- Speak above, or to the side of the microphone. It might sound like this conflicts with point #1, but it doesn’t. You want the microphone to point towards your mouth, however that doesn’t mean you should speak directly into it. Speaking over, or to the side, will help to avoid pops.
If you are a man with a lengthy beard, such as mine, you might find that your beard gets stuck in the microphone occasionally. Unfortunately, I don’t have a great solution for this. You could try using a foam cover on the microphone, although I like to minimize accessories. I should probably spend some time experimenting with positioning the microphone to the side, instead of below my head.
Volume Levels
Aside from choosing a good microphone, you’ll want to control your recording level. Reverberation (echo) from your environment is a common audio recording flaw. To solve for this, you’ll generally want to keep your audio recording levels low. This helps prevent the microphone from picking up unwanted noise. You can always raise the volume level in your video editing software later on.
For my specific environment, I keep the gain on the Blue Icicle’s physical knob at about 70%. Because it’s an analog control, I can’t say precisely where the setting is at. In Windows 10, I set the recording volume for the Blue Icicle input between 40-50%. In OBS, I reduce the gain on the Blue Icicle input about 2 – 3 decibels.
Recording Software Plugins
One of the biggest boosts to my audio quality came from using Open Broadcaster Studio (OBS) to record my content.
Space Beards (jakub Sawczuk) Mac Os Free
Previously I had been using Camtasia to record my screen, webcam, and microphone as separate streams. This separation gave me a lot of power to modify the content in post-production editing. Unfortunately, Camtasia lacks a plug-in architecture that allows you to inject middleware into your audio-video pipeline.
Now that I’ve switched over to using OBS, I can use the built-in plugins and third-party plugins. I recently published an article that talks about using the free ReaFir plugin from Cockos, to reduce unwanted background noises.
Here’s a screenshot of what my audio pipeline looks like. The filters with the eye greyed / crossed out are disabled. This is a convenient feature in OBS, to be able to enable / disable filters without actually removing their settings.
Let’s talk about each of the filters in a bit more depth.
Noise Gate
This is one of the most important filters to use in your audio pipeline. Noise gates work by silencing all audio that falls below a particular decibel level. When you’re not talking, you don’t want the ambient noise of your environment to be captured by the microphone. The noise gate solves this for you.
While default settings may work out for you, you should tweak the Open Threshold and Close Threshold. Basically, the noise gate will stay closed until the decibel level reaches the Open Threshold. The noise gate will continue to stay open until sound goes below the Close Threshold. You should always keep the Close Threshold several decibels below the Open Threshold.

Compressor
The compressor is more of a safety net than anything else. My understanding of how it works, is that if your input audio exceeds the Threshold setting, then the Compressor will kick in and suppress the loudest frequencies.
Your biggest takeaway here is that using a compressor will help prevent audio clipping. Audio clipping happens when your input audio exceeds 0 decibels, and you get a static-like sound. If you have a tendency to shout or get excited about certain topics, then a compressor will save your audio.
In general, you should keep the Threshold setting of the compressor on the higher side. You most likely don’t want the compressor to kick in unnecessarily.
Noise Suppression
Another one of the built-in OBS plugins is simply called “Noise Suppression.” While its name is self-explanatory, it also has a simple configuration. There’s only one setting to worry about: Suppression Level.
If you set the Suppression Level setting to a nominal value, such as -5 to -8 db, you can eliminate much of the background line noise that’s present in your environment.
What Should YOU Do?
Okay, that’s enough talk about my setup. Let’s talk about you now.
What challenges are you facing with audio (and video) recording quality? Leave a comment and let me know what I can help with! I’d love to hear your thoughts on the techniques I’ve outlined above. If your audio quality improve through using these plugins, leave a comment and let me know what worked for you!
Earlier this week Akshat took some time out to chat with open source user and talented designer Ian ‘Izo’ Cylkowski about his work, his tools, and his thoughts on designing in open source.
If the name sounds familiar then it should. Ian is an active designer within the open source community – for example, he created the logo for the semantic app launch tool ‘Synapse’ and has been working with the Novacut team on creating a brand identity for the project.
Izo’s work has also been featured here on OMG! Ubuntu! numerous times. This ranges from us drooling over his wonderfully rich Natty wallpaper and achingly beautiful ‘Ubuntu Tablet Designs,’ to us helping spread word of his work with Dan Rabbit on creating a compressive guide detailing the capabilities of the Murrine theme engine.
So, tell us something about yourself.
The name’s Ian Cylkowski aka “Izo”. I’m 28, British, love simplicity and typography and have a rad beard. I run designbyIZO which is the home of my blog and design portfolio. I’m also an avid fan of FOSS and the Ubuntu operating system as well.
When and how did you become interested in FOSS and Ubuntu?
About four years ago, I think. A friend of mine introduced me to Ubuntu on another forum I was on (he was called “Cookieninja, I believe). I was also extremely interested in computers and tech anyway, and had been venting my frustrations at a Windows XP system I was running that was slowly dying a painful and ugly death. He pointed me to a Linux operating system called “Ubuntu” (at the time, version 6.06 “Dapper Drake” had just been released).
Initially, I was rather weary, as my only knowledge of Linux was that a terminal was often required (I’ve never been a coder/programmer, all that black space terrifies me). He assured me that it was a lot simpler.
So, with practically nothing to lose, I downloaded the ISO, burnt it, booted it, installed it, fell in love with it and have been, bar a few forays with other distros, a consistent user of Ubuntu ever since.
Do you entirely use free software for your all design work?
Almost. In a typical logo and identity design project, for example, a lot of the development of the logo, typography and other design elements are done entirely in Inkscape, which, in some ways, I find much better than Adobe’s Illustrator (though Illustrator is still an excellent piece of software).
I will also break out GIMP when some form of web-safe image editing is required and use Scribus to design my documents, identity guidelines, brief questionnaires and more. It’s only when I absolutely must have Pantone colour system requirements that I then need to switch to either Windows or a Mac to load up Photoshop/Illustrator.
What are your biggest hurdles that stop you from going free software full time?
Mostly, colour management and that means having the software for things like the Spyder monitor calibrator, better colour management in GIMP (although I understand GIMP is currently struggling in terms of development as fundamental aspects of it are being rebuilt); GIMP, as it is, is pretty poor for IRL print-ready conditions.
Inkscape is pretty good for handling CMYK colour models but lacks better PDF exporting options, and Scribus is even better, but we really need to see in-built support for the Pantone CMS and the easy exporting of multiple strains of PDF formats.
To be honest, I’d love to see the day when the likes of GIMP, Inkscape and Scribus are all unified and integrated into one great FOSS graphic design suite, that would be bodacious, but whether this will happen or not is another question. Plus, Scribus really needs to get ported to GTK.
What motivates you to contribute to FOSS projects?
FOSS is very, very important and it has dramatically changed how software is developed, distributed and used in the last decade alone. It signified a powerful change of power from the companies developing the software to developers and users.
Nowadays, anyone is free to download a Linux-based OS, install it, modify it, share it, distribute it and more. This means the pace of development in the FOSS is staggeringly quick. Someone can download a piece of software, check out its source code and submit patches and improvements in a matter of minutes. In the corporate world, such a pace of development is hindered by checks, policy checks, and the wait for many nods of approval from various management positions.
So it’s easy to see how FOSS has changed the game and I think it’s very important that people now have the extremely viable option of running software on their computer that they are then completely free to modify and distribute without fear of retribution and legal punishment for massive global conglomerates… because sometimes just a single person can create something incredible that many millions of people can enjoy. FOSS has become a global community endeavour, sharing, reciprocating, collaborating… it’s a beautiful thing to see.
And, in my mind, one of FOSS’ greatest success stories has been Ubuntu.
When you took up the task of designing a brand identity for Novacut, what expectations did you have?
Well, before one of my blog commentators alerted me to the fact that Novacut required a complete visual identity system, I honestly had never heard of the project; though I think that’s largely down to me not really following the development of video editors.
As I got in touch the project leader, Jason DeRose, and his team, I began to realise that these guys meant business and were extremely ambitious with their goals and desires for Novacut.
It’s been extremely refreshing to see such a coordinated drive and determination in the project. Plus, the guys in Novacut place a strong priority on quality design; this is something I don’t often see in the FOSS world. There are many hundreds and thousands of incredible FOSS apps, but I can’t honestly say a lot of them are beautiful to look at and use. So it was nice to see the Novacut guys wanting to change this.
It has, so far, been an enlightened experience working for them.
What would you like to tell to the designers that are new to Free Software world/don’t know about it?
Largely, be patient, exciting stuff is appearing over the horizon.
GIMP is in the process of being rebuilt with GEGL as the foundation, so that images edited in GIMP can finally move beyond the 8-bit world. Inkscape is getting better all the time. Scribus is immensely powerful.
If you need a graphic design tool for Linux, ask around, there will be someone out there who has been using awesome graphic design apps for Linux that you had no idea existed.
When you first switched to Ubuntu, what were your biggest frustrations with the tools available at that time? Do you think they have progressed a lot since then?
When I first started using Ubuntu, a couple of exciting things were happening, one of which was desktop compositing. Compiz was in heavy development, which forked into Beryl and then the two merged again as Compiz Fusion. Being able to manipulate windows and menus with flashy animations and incredible effects was terribly exciting, especially considering that some of the effects you could do with Compiz were just not possible with the likes of Mac OS X or Windows (see the Cube Desktop Switch effect as just one example).
Of course, compositing required the use of 3D-enabled hardware acceleration drivers for your graphics card and they were very much in their infancy. I remember installing, with success, an nVidia graphics driver on my Dapper installation, installing and enabling Compiz, falling in love all over again and then being driven to despair when a kernel upgrade totally broke Xorg and my display. That was frustrating. Enabling MP3 playback, at that time, was also rather tricky, especially considering that their appeared to be hundreds of different ways to do it.
So yeah, it wasn’t an easy ride back then but the changes since have been incredible. MP3 playback can be enabled during the installation by clicking on a checkbox. A default Ubuntu new install, now, will seek out your graphics hardware and recommend 3D-enabled drivers for your discretion. Installation of these is painless. So these two elements in the Linux world has dramatically improved. And now, of course, we’re seeing open-source 3D-enabled drivers for the likes of ATi and nVidia, which has enabled the new GNOME3 and Shell desktop environment, as well as KDE4.x, to enable compositing by default.
Is there someone in design in free software world that you admire?
There are a few. Jakub Steiner, who is an incredible icon designer for GNOME and SuSE, was instrumental in how GNOME Shell now looks, and also has mad insane skills in web development and 3D modelling and animations.
There’s also Sean Wilson aka “half-left” on DeviantART, who’s taken on theming GNOME 3 and the new GNOME Shell by the horns ever since pre-beta. Dude has some rad skills.
I also love the work of Harno, who’s only 18 and already has incredible Inkscape and icon design skills; he was also instrumental in the identity design of Novacut.
What do you want to tell our wannabe-designer readers?
Learn the basics, I can’t stress that enough.
Jumping onto a cracked copy of Photoshop and applying some blending options on some text doesn’t make you a designer. Start reading. Find some books from the great design masters of the past. Read about typography and learn to distinguish your titles from your stress lines. Read about grid systems and how they’re immensely important in the essential structuring of information and legibility. Read about design masters from the past. Read about design movements. Read about design history. Keep things simple. Look up Dieter Rams’ Ten Principles of Good Design.
Be not concerned with learning how to create specific design objects but instead come to understand the design process, which is much more important.
Ask questions. Question questions. Question answers. Learn what the design rules are, because there’s centuries of design experience that discovered awesome design rules before you. Then break the rules. As long as it looks good. Keep things simple. Keep. Things. Simple.
Get excited about colours. See how past design can be applied to new design in the realms of the web. Try to identity typefaces in every day life. Try to make the world, in your own way, nicer to look at and easier to use.
Which open source projects do you think have good design and an intuitive interface?
In no specific order, just off the top of my head: Google’s Chromium is an excellent redesign of the web browser interface, their implementation of closing tabs, as an example, is inspired; Banshee looks nice and the recent inclusion of offering little avatars for the artist list is definitely an improvement; Amarok, I think, is beautiful; the new Ubuntu One Control Panel is a vast improvement; Ubuntu’s new shell, Unity, is stunning as is GNOME’s new shell, GNOME Shell (for the record, I think both have their good and bad points, and I can see where one should borrow ideas from the other, I need to make that into a post soon); the KDE4.x desktop environment is also totally stunning. It’s an exciting time for design in the FOSS world.
Which projects you have contributed to?
I was once asked quite some time ago by Seif Lotfy of Zeitgeist to design a new logo for the Zeitgeist Project, which I did and then submitted it to the rest of the team. I think that one kind of dwindled away though, there didn’t appear to be any real need for a new logo. Mr. Lotfy also asked me to design the logo and icon for the Synapse smart launcher, which is now currently in use.
Of course, there’s the on-going work I’m producing for Novacut, and in the near future I may be working on the new logo and identity design for the Luz Live Visual Studio app, which looks pretty neat.
I’ve also contributed various wallpapers to Ubuntu and have produced some rather popular GTK and PekWM (a lightweight window manager) themes in the past.
What are some tips for a successful migration from Photoshop/other proprietary tools to GIMP etc.?
Patience, largely. You’ll need to get used to a different interface and, consequently, a different workflow. You’ll have to get used to different filter names in GIMP, for example, as well as generally different names for tools that may have used lots in the Creative Suite.
At this point, the internet is your friend so ask around, do a little Googling, plus Ubuntu has a magnificent community, someone will be able to help you.
With thanks to Ian.
