The Evolution of Audio

There was a time once where it was the standard to record a track with nothing but hardware. From an engineer’s perspective, the band would come in plugin. The engineer would then mic up the vocalist, guitarist, bassist and drummer based on the style demonstrated by the band. These tracks would then be routed though a massive console and outboard effects would be patched in via a patch-bay. The signal would then be routed to a tape machine for record and playback. If there were any errors, the band would have to do the take again. In those days recordings were great not only because the band was great but also due to the fact that they had to practice more in order to get the perfect take.

Fast forward to now and we have DAW software. The workflow for the most part continues on the same path as before with the exception of TAPE and plugins. The signal is routed to the console and from the console to the DAW software. From the DAW software the output channels are routed back to the console in order to enable playback. It is now up to the engineer to decide whether to record to tape or not. Many opt to do so as they claim that the tape enhances the sound.

In reality, all that is necessary to record a band are great microphones, A low latency audio interface with great preamps, with enough inputs/outputs and a reasonably powerful laptop. That is all that is needed. There have been many arguments over hardware vs. plugins that try to emulate that “analog” sound. But let us take this a step back without being over zealous in mentioning any names. In today’s age we have superior audio with a resolution of up to 192 kbps and 24 bit. We never had any where near that resolution with tape. Now that man have accomplished this massive feat, plugin manufactures are now placing the illusion that great mixes cannot be made without these “classic” hardware models. This is simply not true.

In simple terms: a compressor is a compressor, an eq is an eq, and distortion is distortion.

A compressor is designed with only one thing in mind, and that is to reduce dynamic range.

An equalizer was designed to accentuate favorable frequencies to better sculpt the audio spectrum. Anything else is distortion, which in many cases can prove to be unfavorable and yet quite favorable in some instances. Alexander Lindo has experienced many different pieces of hardware and software used to emulate the corresponding hardware and he can confidently say that the differences are greatly exaggerated. A knowledgeable engineer can get a usable sound out of most compressors. Having said that the SSL 4000 Buss compressor and the 1176 are two excellent compressors. The 1176’s super fast microsecond attack time distorts the incoming signal, giving it a perceived “liveliness”. The SSL 4000 Buss compressor add life and consistency to a mix through the use of distortion as-well.


A Take on Cheap Bluetooth Headphones

AL MPOW 059.jpg

Bluetooth headphones are the future of portable audio and one would be foolish to ignore their presence considering the wealth of high quality options available. However that is not what Alexander Lindo will be discussing in this article, instead, he will discuss his thoughts on the MPOW 059 Over-Ear bluetooth headphones (aka MPOW review). They are currently the best-seller on Amazon in their respective category.

Now, as a certified audio professional who mainly listens to and composes rock music, Alexander can safely say that at this price point you are not going to get Sennheiser, Bose or Beats audio quality out-of-the-box (quite the opposite in fact). However, for the price these are useable headphones that are more than capable of providing decent audio quality (once the right adjustments are made). The MPOW 059 (also called the MPOW M3) requires a bit of frequency gain reduction between 60-250Hz to reduce boom and a boost at around 16kHz to establish clarity. Once you’ve done that you’ll have a more balanced sound from these headphones.

The bluetooth volume controls, and battery status bar indicators of these headphones are natively supported on Android (but not on macOS.) In other words when you adjust the volume on your headphones it will directly adjust the volume control on your Android device. On the Mac the headphone’s volume is independent of macOS. Play/Pause and Skip buttons work natively on both platforms.

There are no latency issues when watching video. Lips move in sync with audio.

The MPOW 059 supports the SBC audio codec exclusively, which means no AAC or AptX is present. It would have been great to see support for AAC seeing as it is a superior codec to SBC but nonetheless sound quality is reasonable.

macOS users will need to download the “Hardware IO Tools for Xcode” from Apple’s developer page in order to get the “Bluetooth Explorer” application. This application will allow you to increase the bitpool value from its default value of 40 to 53. This will dramatically improve the audio quality of these headphones and any other bluetooth headphones that rely solely on the SBC codec. For those who want specifics: a bit pool value of 53 is equal to a bitrate of 325 kbps. SBC at 325 kbps is the equivalent of MP3 at 256 kbps. When the you’ve downloaded “Hardware IO Tools for Xcode” and have opened the Bluetooth Explorer app you will see the app’s name in your menubar. Go to “Tools > Audio Options” or “Command + Shift + A”. This will bring up the window for you to edit the SBC audio settings. Under “SBC Codec Options” Set all bitpool values to 53 and close the window. This will ensure that the audio quality remains optimal. Close the window and re-connect your Bluetooth headphones.

Build quality seems reasonable, hinges are reinforced with metal. Only time will demonstrate the endurance of these headphones but superficially speaking the headphones appear to be quite sturdy. The ear-cups and headband are made of a soft synthetic leather which provides initial comfort but they are a bit shallow in depth and can place a bit of pressure on the ears when the headset is worn for an extended period of time. Battery life is reasonable. Accessories include a micro-usb cable for charging and a 3.5 mm audio cable which is handy for more critical listening and for events in which the battery has lost its charge. The velvet-like pouch is a great inclusion and provides protection against dust and scratches. These headphones are definitely worth the price and Alexander doubts you’ll find better at this price point.

Logic 10.3.2


AL LPX 10.3.2Apple fixed the GUI bug present in some of its Retina-Optimized instruments and plugins in LPX 10.3.2. For those who took notice, some of the stock Logic Pro X instruments and plugins produced an annoying graphical bug in regards to the number entry field when placed on any scale factor other than 100%.

Some of the plugins affected by this issue included: Retro Synth (in the screenshot above), Vintage B3, Vintage Clav, Vintage Electric Piano, Drum Kit Designer, Compressor, Channel EQ, Linear Phase EQ.

In the past: The blue halo that appears around the number entry field was distorted and out of place. That issue has now been resolved. The blue halo that appears around number entry field now complies with the scale factor of the plugin. Rock on Apple!

Upgraded to Sierra

LPX & Waves on macOS Sierra – Inst

Alexander Lindo upgraded to Sierra and he is glad that he did. In his words: The OS feels much faster and lighter than El Capitan and the new optimized storage features are certainly a welcome addition.” Logic Pro X appears to be working much better than it was on El Capitan and best of all, and he is no longer having audio drop outs / distortion when using applications such as iTunes.

After copying over all his useful content (such as music, photos, videos etc.) from a backup, his first step after installing a new OS was to create a backup. For this, he used Time Machine. The backup went through just fine with the exception of “iCloud Drive” which took a while to download content during the backup process. Once all iCloud content was downloaded, the backup process was complete.

Alexander opened up Logic Pro X and tested it without any 3rd party plugins installed. The DAW was as fast as its ever been since the OS X Mountain Lion; certainly a plus in his book. The next step was to install 3rd party plugins. Many companies in this area have warned users not upgrade to Sierra yet. Of course that did not stop Alexander as he tends to keep 3rd party plugin dependency at minimum. He opened up Waves Central and installed a local backup of his plugins after which he authorized. At first it did not authorize but this may have been due to the unstable internet connection at the time. After trying again it worked.

Alexander opened up Logic Pro and his Waves plugins were fully operational. He even recorded, mixed and mastered a song. Performance wise the improvements are certainly visible.

Plugins from Plugin Alliance do not work officially yet as told by the manufacturer however, he has found a temporary solution that will work until the problem has been officially fixed. See below:

  1. First copy the auvaltool file from the /usr/bin folder from your El Capitan install on to a USB Stick.

  2. Restart your Sierra install and hold down Command + R until you see the Apple logo and loading bar.

  3. Once in recovery mode, Open Terminal from the Utilities menu and type csrutil disable

  4. This will disable System Integrity Protection, which will enable you to replace the auvaltool on Sierra with the one you copied from El Capitan. Be sure to keep System Integrity Protection disabled while you use the previous auvaltool otherwise the it will not work anymore.

  5. Once a fix is officially released, simply replace the auvaltool you copied from El Capitan with the one installed by Sierra.

  6. Reboot your Mac and hold down Command + R until you see the Apple logo and loading bar.

  7. Once in recovery mode, Open Terminal from the Utilities menu and type csrutil enable in order to re-enable System Integrity Protection.

After following steps 1-4 you may need to configure file permissions. Do the following:

cd /usr/bin

sudo chown 0:0 auvaltool

sudo xattr -c auvaltool

sudo chmod 755 auvaltool

Disclaimer: Please note that this temporary fix is not endorsed by Plugin Alliance and you must use at your own risk. Plugin Alliance say that they are working on an official fix. SIP must be disabled in order for this workaround to work and should be re-enabled as soon as an official fix is released by Plugin Alliance. Disabling SIP (System Integrity Protection) poses a security risk and should only be disabled when it is absolutely necessary.

Alexander Lindo’s EP entitled “Progression” has been released recently and is available for purchase on iTunes, Amazon MP3 and Google Play. BUY IT NOW!

Update: Plugins by Plugin Alliance now officially support Sierra.

Studio Tips – Episode #1


Music is an art-form. It builds, strengthens and enhances the human life. It is built with the purpose of delivering a message. It is therefore extremely important to ensure that (as artists, producers, and engineers) our message is delivered in the most accurate way possible. In the “Studio Tips” series I discuss methods on how to enhance the experience and delivery of “the song”. Enjoy!


Ensure your environment is optimal as an uncomfortable environment will leave you with a poor performance. Surround yourself with people who love you for who you are, what you do, both as an artist and as a person. Do not be quick to “take what you get”, as you always have options. Never let anyone make you think that you don’t have options. If you are unhappy with the situation it is bound to show.


If your intention is to record, make sure that you have adequately practiced the material before hand. Magic can and may happen in the studio but it is always best to prepare. If you are a singer ensure that you are hydrated, as failure to do so may leave you with some dry sounding vocals. If you are a guitarist ensure that your guitar is properly tuned and that you have at least 2 extra set of strings available. Other than failure to prepare it can be equally disconcerting when the performer is unable to record a take due to technical difficulties. If you are the producer/engineer set up your project with plugins that introduce the least amount of latency / CPU usage during tracking / recording.

The Message

Vocals / Lyrics are the most important part of every song (that contains vocals). They tell the story, and you want them to shine to the best of their ability. Be sure that your engineer is providing you with a space carved out just for you. Listen to the mix. If you cannot hear yourself clearly when the music is playing, you will be shouting above the mix and this is never recommended. The same goes for performing live. If you cannot hear yourself, you will not perform correctly. It is therefore extremely important to get the balance right, before you open up.

Upgrade Icons on Ubuntu


You may have installed new applications, however those new applications come with not so new icons. They may provide you with ugly low resolution icons. Or you may have installed a beautiful icon theme like Numix-Circle and may be wondering why some of your icons have not changed. Never fair, you do not have to suffer with the presence of these low resolution icons, as the solution is simpler than you might think.

First look for the Application.

This is the AVI Demux application icon. Alexander obtained this variant of the application from as it was more up-to-date than the one present within the official repositories. As you can see, this application has decided to stick its low resolution icon instead of using the one present in the Numix-Circle icon suite.


In order to solve this problem we must first understand the basics of how Ubuntu handles applications and their icons.

Ubuntu stores the Unity Dash shortcut configuration files in /usr/share/applications 

All configuration files in this directory feature a .desktop extension to indicate that it is an application launcher configuration file.

And all icons referenced by those configuration files are normally stored in the /usr/share/icons directory.

You will need to gain root access to edit the configuration files. This is Ubuntu’s way of protecting you from yourself, so to speak. A lot of things could go wrong if you were to be the root user 24/7 for this very reason you are not a “root” user.

First open a Terminal window (Ctrl + Alt + T) and type sudo nautilus
This will open a Nautilus window with root privileges.
Go to usr/share/applications

The following window will appear:


As you can see, the Avidemux icons “appear” to be present in this folder. This is not the case as these are simply just shortcuts referring to the actual icons located in usr/share/icons

Let us go there and investigate.


You can see that the icon Alexander Lindo has highlighted is avidemux.svg. It is there but it is not appearing in the launcher or the dash. This simply means that the application’s shortcut configuration file is not referencing the icon from the Numix-Circle icon suite but is actually sourcing its icon from another directory (either from within the usr/share/icons folder or sometimes in it’s own folder).

An example of this is the Xdiagnose application. It sources its icon from /usr/share/xdiagnose/icons/microscope.svg 

This means that, no matter what icon theme you use it will completely ignore it.This can be resoloved using the same method mentioned in this tutorial.

Close all your open windows and then close your terminal window.
Open a terminal window and type sudo gedit
This will open up the text editor with root privileges, enabling to edit configuration files editable only by the root user.
Hit the “Open” button and navigate to usr/share/applications

Click avidemux2.6-qt.desktop and click Open

The following window will appear:

Look at the Icon field. You can see it says: avidemux2.6-qt
Change this to avidemux and hit Save.
Or, alternatively, If you would like to have a backup in case you mess up just comment out the Icon=avidemux2.6-qt with a # so it will look like #Icon=avidemux2.6-qt
The field will become blue indicating that it is inactive.
Now you can hit Enter and type: Icon=avidemux in the next line.


Hit Save, close all windows, log out and log back in and you’re done.
