A Microphone Deep Dive: Part 1 – Frequency Response

Last week, in response to Chris Koehncke’s blog post, I set about creating a couple of sample recordings to support my belief that a headset trumps a laptop’s built-in microphone. Along the way I came to a couple of realizations, or perhaps I should say remembrances, of things that I hadn’t thought about in a long while. There are numerous subtleties to the matter of microphones.

Microphones, like most things, are built to address specific applications. There are microphones for recording studios. Microphones for stage performers. Microphones for board rooms. Microphones for mobile phones. Even a microphone for that cheesy tape recorder that you bought at Radio Shack back in the 1980’s when it was still a great gadget shop.

Kranky & Krankier?

Chris Koehncke (aka Chris Kranky) recently posed a question in a blog post. He asked, “How good is your laptop microphone?” He then laid out an experimental series of recordings using different hardware. As an executive summary he offers, “Your current internal laptop mic is probably fine.” As you might imagine, I disagree…but there’s more to it than that.

In truth, it’s not that he’s wrong, but I think that he was asking the wrong question! The question he should have asked is, “How do I best convey my voice when using this laptop?”

The answer to that question is quite simple…use a high-quality headset, preferably one with a boom-mounted microphone. When participating in any kind of conference call, or video conference nothing can touch the quality of sound delivered by using a good headset. This has long been my belief, although I accept that it may not be a widespread.

User Experience: T-Mobile’s Continental Plans

TMobile-Phones-CoOmpositeEarlier this year T-Mobile altered their US Simple Choice Plans to include coverage in Canada and Mexico without roaming charges. The plans eliminate roaming while out of the country, but also eliminate international long distance when calling Canada and Mexico. Further, they include “4G LTE data in Canada & Mexico.” Since we go to Canada to visit family at least once a year the new plan sounded quite useful.

Change is hard…

Last month we made our annual trek to the Great White North. While making plans an associate, who is also a T-Mobile customer, recommended that I call T-Mobile and make sure that we had the correct plan. Failure to do so would result in us incurring the usual roaming charges for platinum-plated voice and data service while travelling.

On the very eve of our departure I remembered to call T-Mobile and make the change to the account. In fact, I called from the airport (IAH) while we were awaiting the departure of our initial flight to Toronto.

Of course, I called the from my mobile phone. The automated system advised that there would be some on-hold time, and I could opt to have them call me back, which I did. The callback took about ten minutes.

Chances Are Your Router’s Firmware Blows

Linksys WRT-54G RouterYou surely have a lock on your front door. Do you have such a lock on your network? Though you may think so, but it may well be wholly unlocked. Or at least, you may not be able to know for certain that it’s locked. If you use a commercial Wi-Fi router from your ISP, or one of the big names like Linksys, Belkin, DLink et al, your network may not be as secure as you think.

At the outset let me state that, as someone who reads hereabouts, you’re no dummy. You’ve taken steps to ensure that the router doesn’t still have  the default admin password. You’re using modern encryption on your Wi-Fi. You’re being responsible, but there are things beyond your grasp.

The simple fact is that the firmware the runs most retail, commercial routers is closed source. As such, you have no ready way to verify it’s behavior. Yet, the manufacturer, by virtue of necessity, uses various common software modules to create their firmware. They may even use some open source modules, but end up with an closed source binary in the end.

The upshot of this reality is that you have a very small team of developers responsible for maintaining the code. That means updates come along slowly, if at all for older devices. By extension, serious security issues get addressed slowly, if they ever get addressed at all.

VU Meters For Windows

Some time ago I noted the availability of installable audio metering for Windows. Today I stumbled upon a similar free application called “VUMeter” that provides old school stereo VU meters.

The meters can be resized from 50%, 100% or 200% of normal size, where  normal size is 1500 x 300 pixels.

They can be set to stay on top of all windows. They can also be set to display the signal from any available sound recording or playback device.
