Audio-Technica are a long-standing manufacturer of professional microphones, headphones & turntables. Earlier today they released a nice video documenting their difficulty in achieving good audio pickup from a zombie. I think it’s great that they selected a head-worn microphone as…
It’s Q4-2014 and HDVoice is now largely passé. On that basis one might think that it’s use should become evident, especially amongst the telecom cognoscenti. So I was surprised to hear the most recent UC Strategies podcast entitled, “Connecting the Circuit.” This podcast, a discussion of a new UC service called “Circuit”, was derived from a conference call of leading telecom experts.
Sadly, with the exception of a little music at the beginning, the recording exemplifies the finest narrowband audio traditions of the last century. This is, to my mind, a disappointment. It boggles the mind to think that some of the leading thinkers about UC, are not themselves taking advantage of one of its core features…HDVoice.
Woot.com is today offering the Lenovo X1 Carbon Touch Ultrabook for $899 & $999. I own the prior model, which is not touch enabled. Even though it’s coming on two years old I still like it a lot. It was…
A 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/
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.
The folks over at VoIP Supply have started what they hope will be a series of interviews of bloggers in the VoIP-o-sphere. It happens that I was featured in the first installment in the series, which was posted a couple…
