On a shelf in the garage that adjoins my home office there is a set of shelves with a number of boxes of cables. There are cables of various sorts; BNC type video, RCA audio leads, XLR audio cables, IEC…
Earlier this week Gigaset extended their Gigaset Pro line by adding a new 10” Android tablet they call Maxwell. I must say that at first glance the device looks VERY nice.
As just an Android tablet Maxwell is a little unremarkable. The display is 1280 x 800 pixels. It runs Android 4.2.2, aka Jelly Bean, which is a little old on the eve of widespread Lollipop rollout.
What makes Maxwell stand out from the crowded tablet marketplace are the customizations intended to make it a communication centerpiece. These include;
Color me curious about this tablet. I’d simply love to lay hands on one. I suspect that won’t happen since their Gigaset Pro line has not been offered in North America. The only thing that made it to these shores was the Gigaset DX800A
While I recently lamented the last UC Strategies podcast woefully narrowband presentation, in the interest of fairness I must today point out that they are not alone in this. Today the latest No Jitter Podcast, hosted by Guy Clinch, published an interview with Andrew Prokop of Arrow S3. It suffers a similar lack of lack of regard for HDVoice.
Mr Prokop’s SIP Adventures blog has proven interesting, so I thought the podcast worth a listen. Sadly, while the host is presented full bandwidth, as might be expected from a local recording, the guest is presented in narrowband. Given that the subject matter is WebRTC I think that this is more than a little anachronistic. WebRTC-based services are in fact a very easy way to enjoy wideband audio for the purposes of producing a podcast.
Dragging the podcast in my trusty editor I find it to the a definitive example of full-band audio vs narrowband. The file is sampled at 44.1 kHz, so the top of the vertical axis is 22 kHz. The guests audio is a good quality PSTN call, but even that is quite a contrast from the host. This contrast is very jarring to the listener.
Today’s news dump included an article on GatesAir, now a freestanding entity, it was once the transmission division of what was then known as Harris Broadcast. The company makes radio and TV transmitters, as well as related equipment, which includes studio-to-transmitter (aka STL) links. According to the Broadcast Beat article they have sold and installed one of their Intraplex IP STLs to WRLY-LP, a low power radio station in Raleigh, NC.
A broadcaster with a transmitter that is not located right at their main building (not co-sited) needs an extremely reliable means of sending their broadcast signal from the studio to the transmitter location. They also need some way to get some transmitter telemetry back from the remote location so that they can monitor the health of the transmitter. Their on-air presence via the transmitter is, after all, their bread and butter.
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.
