Some Guidance On Headsets

Passport_21_OTH_3_QTR_RightA couple of weeks ago, over at the Broadband Reports forum on VoIP Tech, there was a question posed about selecting the best low cost microphone for VoIP applications. This is a topic that I’ve considered at length. It has much in common with my background in recording and broadcasting. On that basis I weighed in with some opinion. As I my way, I probably provided a longer answer than anyone anticipated, or even wanted. After re-reading it a few times I thought it worth sharing here as well.

The original question:

I realize many problems people experience are due to a lousy mic that isn’t noise canceling or picks up sounds from a anywhere in the room. There are many ways to improve this. I like the idea of a pickup pattern that is very isolated in front of the mic and within a finite range so I don’t have to wear the mic but maybe this is asking too much. If the mic only picks up sounds very close to it, wearing it can sure avoid a lot of problems. Don’t know if firewire or USB3 is better than USB2 or if its better to run the mic directly into your mic input of your motherboard or audio card or something else. Latency is not our friend! VOIP is so sensitive to extraneous noise so this needs to be addressed and is dependent on the ambient noise of the user. Any recommendations? Few of us work in a soundproof office.

As a long-time and vocal proponent of headsets for office use this is right in my wheelhouse. For example…. https://www.mgraves.org/2011/07/can-you-hear-me-now-headset-vs-speakerphone-in-the-home-office/

Webcams 7: VDO360 Serious Webcams For Business

It was around a year ago that went on the hunt for a USB 3.0 webcam, only to find that they were essentially nonexistent. In my quest what I discovered was a range of products beyond the familiar consumer webcams. These are serious webcams for business, offered by companies like VDO360.

That companies’ initial product, the VPTZH-01 HD USB PTZ Video Camera, was novel for its VISCA compatible pan-tilt-zoom (PTZ) capability. It was introduced at around $1399, a price that was heralded as a breakthrough at the time. Award-winning in fact. The current street price, as exemplified by Amazon, seems to be $999.

The VPTZH-01 HD USB PTZ Video Camera is a USB 2.0 connected device, with all that entails. The sensor is capable of delivering images up to 1920 x 1080 pixels (1080p.) Most applications will only manage to access a 1280 x 720 pixel (720p) stream since they are taking uncompressed frames from the camera.

Applications that are sophisticated enough to setup the camera to deliver a stream of MJPEG compressed images will be able to get full 1080p quality for the effort. The MJPEG compression overcomes the bandwidth constraint of the USB 2.0 connection to the host computer.

Making Some Noise About Noise

Snapper-lawn-mowerThis morning my normally tranquil home office was pierced by the sound of a neighbors lawnmower. The lawnmower, while aggravating, is just the lead-in to that most vile of power tools…the leaf blower. Leaf blowers should be outlawed.

All of this has thinking about noise. In even modest amounts, noise degrades our ability to communicate. Beyond simply annoying, it hampers productivity. Therefore noise has very real costs. Nowhere is this more true than in the case of conference calls or video conference calls. These are cases where extraneous noise should be avoided.

The classic conference call wisdom, good advise to this day, is that all participants to should diligently mute themselves when not speaking. People being what they are, many do not know of or act upon this belief.

When using a managed conference bridge, like ZipDX, the call moderator has the ability to mute a noisy participant, ensuring that their local acoustic reality doesn’t degrade the call experience for everyone. That’s great, but it really just allows the moderator to compensate for the fact that someone on the call is exhibiting poor conference call etiquette.
