Living with the Zoom H24 24-channel digital recorder · Monday March 5, 2018 by colin newell
Recently one of my colleagues at the University of Victoria loaned me one of his studio tools that he was thinking of parting with – The Zoom H24 24-channel digital portable recorder.
Now for the record, way back when I first started recording multi-track style I was using a cassette tape based TASCAM 244 – 4 tracks of audio on a cassette… and that was mono tracks. Granted, the Beatles recorded some amazing music on recorders not much bigger than that… but I am not them.
Anyway. Armed with a couple of good microphones, headphones, a guitar, ukulele and a bass guitar I came up with a bunch of sample demos (warts and all…) way faster than I could have on my PC based audio work-station. Here is one. Trust me: Listen on headphones or ear buds!
Gear: APEX Floating plate microphone and Shure SM81 condensor microphone.
Cort acoustic guitar, Kala Ukulele, Godin bass – and three vocals provided by yours truly.
The Zoom H24 digital recorder is jam packed with features and to be honest, I likely utilized less than 5% of its capabilities. For instance, the R24 offers eight inputs on combo connectors that can accept either XLR or ¼” balanced or unbalanced cables.

All inputs can handle mic/line/instrument level signals, and Input 1 can also handle low impedance signals from passive electric guitars and basses.
I took advantage of the phantom power (+24 or +48 volts) which can be applied to up to six inputs, allowing the use of professional grade condenser and floating plate microphones. I use Chinese made APEX cardioid patterned plate microphones at around 1/10th the price of a German made Neumann U-87 (which sounds utterly dreamy with the right voice!) and for my voice, it’s just fine. I use the SM81 for picking up some of the features of my acoustic guitars but plugging directly into the R24 works just as well.
The Zoom H24 can record 8 tracks at the same time and works really well if you are a band that wants good isolation for fine tuning after a recording session. I found that I could easily eat up 8 tracks with just a couple of guitars or a ukulele and some vocal harmonies. Another great feature is the ability to bounce, swap or transfer tracks around with the press of a button. Example: I have my microphones plugged into inputs 2 and 3. When I get the take that I am happy with, I “bounce” those tracks over to Channels 4 and 5 and carry on (having now left tracks 2 and 3 to record on again.)
The Zoom H24 has velocity sensitive drum pads and built in rhythms – and I never got anywhere near them. There are hundreds of effects for most electric stringed instruments and a wide variety of mastering algorithms for mix-downs that I could literally fill a page commenting on. Bottom line: If you are a singer or guitar player or podcaster who wants to produce broadcast ready materials or demo’s worthy of a listen with the pro’s, this could be the right tool for you.
In the following “sample” I used a single APEX microphone to record one lead vocal, two harmonies, 3 tracks of guitar picking or strumming, an electric bass track and a ukulele – there is at least one jarring rhythmic error in this track but you get the general idea. Singing and playing aside, it is pretty amazing what you can do quickly.
The manual is fairly helpful but you do need some background in the concepts of recording and mixing – and there are a few useful YouTube videos for getting started.
Starbucks on the recruitment drive · Wednesday October 30, 2013 by colin newell
Starbucks is dedicated to hiring 10,000 veterans and military spouses in the next five years.
Organized in part by Starbucks board member and former Defense Secretary Robert Gates, the Seattle coffee giant said it hopes to “enlist” the unique communication, leadership and problem-solving skills most veterans and their families already have.
Quoting a recent L.A. Times article, “The hiring effort, which would affect Starbucks’ U.S. stores, is also a reaction to the “exorbitantly high unemployment rate that military families and veterans face,” Starbucks Executive Community development officer Blair Taylor explained.
Starbucks will set up recruiting processes “specifically targeted at veterans,” he said. The chain is “just starting to track military hires,” he said.
Other major U.S. businesses, like Walmart, have recently made efforts to pull employees from the nation’s defense forces.
Starbucks will open five community stores at U.S. military bases over the next five years… much like Tim’s does in some of its Canadian bases abroad.
Fascinating stuff in light of the some of the many challenges veterans and their families face as they return to civilian life. Hats off to Starbucks.
Updates, this that and those other things... · Monday July 29, 2013 by colin newell
Nothing like staying awake several hours in the night worried about the fact that two of your main websites are dysfunctional after a suggested system update.
In this case, a software update was made to my main coffee website and my main telecom/radio website.
The radio website has a huge technical library on board with a modest subscription service…
meaning I get some coins when someone wants to browse the growing library.
And that makes sense – In many years, my tech library gets upwards of 60,000 document downloads.
That is bandwidth that I have to pay for.
Since instituting a fee subscription service (and a request for donations to keep the service running), the response has been very favorable.
Meaning if you need something, all you need do is ask.
Because everyone is generous… for the most part.
And what of the guitar? I am currently testing out an amazing “black box” for a company that I cannot currently name – it is actually a vocal processor that does natural sounding harmonizing, pitch correction, commercial grade effects rack, phantom power for commercial microphones and lots more. At some point, if I get permission I will review it – and you will get to hear me sing… in many different ways.
Yea. Look forward to that!

Living in a wireless world - safe yes or no · Wednesday November 14, 2012 by colin newell
Wifi – Safe: Yes or no?
In an era of great technological advance, the question always arises – how good are these advances, conveniences and marvels of technology for us… in general? You know, our health… mental and physical.
I, for one, am typing this blog entry on a Macbook Pro connected through a secure wireless network – and I know my router pretty well… I customized the settings – I have the power level at “medium” – most people are not aware that they can tweak their routers in a myriad of ways – and for me, setting the router output power to a level that works within your work space makes sense in a variety of ways; 1.) It is more secure if you keep your range within the confines of your home and 2.) It adds the minimum of wireless energy to existing orchestra or medley of wireless signals in your living space.
And so you know: I do not believe for a second that 1 device or the output of a handful of devices is going to harm you in any quickly identifiable way – the scientific evidence is not really there.
What I do question (actually I question a couple of different things about this topic area) is the immediate acceptance of any technology that is foisted upon us (or, ahem, introduced) without a sound fiscal or technical rationale for spending a small fortune on introducing the technology. And I know this is kind of late in the game but I heard recently that there have been some perfectly sound judicial decisions about the technology and some of the responses from some local media types is that the Tin foil hat wearers and those that suspect that their PIN Numbers or souls are being stolen by this technology need to relax or take a pill. Which, to me, is nothing more than cruel bullying – and are we not on that very subject of bullying a lot lately?
My point is – I respect anyone (smart or not so much) that questions stuff, any stuff – and even if their claims are a little off the wall, there is no reason to insult anyone.
So: More on where I am coming from. My actual area of expertise is electronics engineering technologist – and my main discipline is, guess what, telecommunications. So I know a little bit about wireless technology. So, let’s talk about wireless for a bit… and wireless radiation.
There are two types of radiation in nature: Ionizing radiation and non-ionizing radiation. Examples of non-ionizing radiation include cell phones, routers, ham radios, walkie-talkies, radio and TV transmitters, hair dryers (yes, hair dryers) – virtually any electrical or electronic device that has “inductive” properties (has a motor), modern power supplies (like a wall wart for a laptop computer) – even computers themselves radiate a bit of energy on a broad range of frequencies.
Examples of ionizing radiation include X-ray machines, ultraviolet light, gamma radiation and all that neat stuff that nuclear weapons and processes throw off. The thing about ionizing radiation that is bad is: It can (and does) alter your DNA, cause cancer and/or birth defects. It is that simple. No one questions this.
Non-ionizing radiation and electro-magnetic radiation are being studied from many angles for their potential health effects. Here are some examples of what we know. High levels of microwave radiation from cell phones, cell phone towers, radio transmitters, high power routers and other transmitting devices raise your body temperature (when in proximity of the device)… raise it slightly. What the effects of this we are not clear on. Thing is, we have not been using this technology for very long – it is the product of modern living (as in the last 110 years or so…)
When you think about it for a minute, modern medicine is the last 100 years worth of advances. It was not that long ago in history that we discovered antibiotics, antihistamines, remarkable drugs for all kinds of things – even treatments for cancer that were non-existent only a few years ago. And humans have been roaming the planet for thousands and thousands of years – so, point is: A lot of what we are doing today is pretty darn new.
My bigger point: It was only a few years ago, that people would suggest that folks with Fibromyalgia were imagining their symptoms – was all in their heads. This condition is now accepted to be real.
I personally know people that swear that they are effected, in some way, by the presence of high tension power lines (you know the ones, the 300kv transmission lines that cross many rural areas.) There is no physiological reason why anyone should be impacted by the presence of AC power lines near their home – that we currently know of. But who knows what we might discover in the future. We are, after all, bio-electrical creatures… so, who knows right?
Back to the wireless stuff and the smart meters: If you have ever been to the symphony, you will notice that everything seems pretty quiet during the violin solo – and then the rest of the violins kick in and the other strings and then the percussion – My point: 1 or 2 wireless devices in your immediate area are likely not doing you any more harm than running a hair dryer near your noggin – and definitely less of an issue than using a cell phone for 1/2 hour a day. But the more devices that are around you, the higher the levels of energy – it is that simple… and remember this:
The level of energy you encounter from any device drops, in intensity, is at the inverse square of the distance – simply, at 2 feet away, the energy is 1/4 and at 4 feet away it is 1/16th etc. It drops off pretty quickly.
So: Are Smart meters harming anyone? Well. That depends. If one burps out a burst of wireless data every minute or so – more or less at the level of a cell phone and you have one in your home, chances are, it is competing with a bunch of other devices – and some of them are chattering even more frequently. And if you live in a condo or high rise and there are dozens or hundreds of units in your space, then there are hundreds of these device ejaculating bursts of 900+ Mhz energy almost continuously.
Good or bad, we do not currently know.
What I do know is that it is likely less healthy to stress out about it and raise your blood pressure about the possible effects of something that we do not completely understand. If the average person finds these technologies intolerable, then they should have the option of limiting their exposure – and for sure they should not be ridiculed in public or privately. I have been seeing a bit of this in the social media realm and it sickens me. The same person that would ridicule someone who objects to this technology or fears it or questions the wisdom of the investment is clearly the same kind of person who abhors the sight of a handicapped person, a child or adult with a learning disability or someone in a wheel chair… etc. I think my point is clear. Bullying anyone who fears something, legitimately or not does not deserve your pious judgement.
For now, I can sleep at night knowing that all this technology is likely not killing me (that I know of…) and yes, I am an expert on the subject.

Toshiba Netbook NB555D quick look · Monday December 19, 2011 by colin newell
Having acquiesced to pressure from my chief significant other (she) having grown tired of watching me hover over my Asus Eee PC 4G (and its 7” screen) like a microbiologist examining a specimen…
I finally departed mid-2007 and came into the modern times with a Toshiba Netbook model NB555D. In good time too – we have been hauling the little Asus around the World (well, back and forth to Hawaii to be exact) for many years now – running its native Fischer-Price style of Linux (Xandros if I am not mistaken…) and a handful of Live USB sticks with iterations of Ubuntu just to be safe.
I had just become fully comfortable manipulating the OS on this little sub-notebook sized unit (just installed “Leeenux” – a light duty version of Ubuntu even less bloated than Easy Peasy… The Asus Eee runs great, still does – and it will travel more – just not on the next Hawaii trip – coming up in a few weeks.
The search for a slightly better netbook was not a long one – managed to zero in on the Toshiba Netbook model NB555D fairly quickly. Simplified by the fact that I did not want another Asus (at least right away), did not want a Sony, and did not want anything running Android on a device that would be locked to that OS.
What I found kind of interesting and slightly annoying was the complete lack of any credible peer reviews of the Toshiba Netbook model NB555D – nothing. One 1 paragraph review and a you tube link. The rest were ads and zero content lazy shills with links to vendors – more of the net seems to be like that sadly.
Anyway – what of the Toshiba Netbook model NB555D? With a 10.1” LED back-lit screen and a decent size keyboard (for my large hands…) and an energy scrimping Ghz AMD processor – (superior video processing to its Intel brethren in another similar model number) – and an attractive blue shell (and an interesting finish…) I guess I was prepared to be happy from the moment of purchase.
That would not come immediately.
The Toshiba Netbook model NB555D ships with Windows 7 “starter” – but let’s call it what it is – Windows “stripped down” is more like it – but that is OK all things considered. And here is one reason why:
Windows 7 is a memory guzzler. The Toshiba Netbook model NB555D ships with 1Gb of DDR3 1066Mhz RAM – which is what the Toshiba Netbook model NB555D needs to be happy – leaving little left over for apps.
Out of the box, the Toshiba Netbook model NB555D is a slug until it gets through a series of software updates and software self optimization (A windows 7 feature – it actually “learns” some of your preferences and practices as you use it more…)
One of the first things I did was axe the “Norton Starter” that comes with it – I use AVG Free for virus protection but Microsoft Essentials (Free anti-virus) would have been a good choice too.
Next I loaded “CRAP Cleaner” – a great tool from Piriform.com (also free) and got into the start-up manager and pulled a bunch of useless utilities and “launch speeders” that accelerated the appearance of the “Login screen” from a miserable minute and a half to a respectable 50 seconds.
In a head to head with the 2007 Asus Eee 4G PC, the faster machine (the Toshiba Netbook model NB555D) actually lagged the Asus oldie in every instance.
Using Crap Cleaner really got things zipping – still slower than the much older Asus however. More on its performance after I upgrade to 2G of RAM (in a few days)… with more user comments and software tweak suggestions!
