G.722

Answering One More Question About HDVoice

Picking up where I left off some time ago, there was one more question arising from the earlier thread in the VoIP Forum at Broadband Reports. PX Eliezer asks:

4) G.722 is royalty-free. That being the case, and if it is not a bandwidth hog, and if it sounds great, then why do so many Voip providers, and so many manufacturers, not support it? In other words, why has adoption been so slow?

There are many factors that have contrived to slow the progress in implementing HDVoice on a broad scale. So many in fact that just pondering them has delayed my response to your question. I didn’t want to drift around a range to topics and make the matter appear utterly insurmountable.

Making Use of Wideband Voice Right Now!: Blink & SIP2SIP.INFO

Not yet making use of wideband voice? That’s outrageous! It’s so easy, and I’ve given you so many ways to give it a try. Here’s yet another way to try wideband voice…and it’s absolutely free.

Blink is a relative newcomer to the realm of soft phones. Offered by AG Projects Blink was initially released in December 2009 for the Mac platform. Since it’s based upon the Qt framework they were eventually able to offer Linux and Windows releases as well.

VUC founder & host Zeeek has on several occasions expounded on how well Blink behaves on his Mac. Further, Blink supports wideband audio via the G.722 and SPEEX codecs.

Myth-busting: Audio Bandwidth vs Data Bandwidth


Few things get me as agitated as the flagrant spreading of disinformation on the part of the plainly ignorant or apathetic. How’s that as an opening line for an argument? Well, it’s a fact.

As mentioned previously, recent weeks have seen some developments in the war against low-def voice. HDVoice service in the UK is getting easier to find, even in the mobile space.

This is very encouraging. Like the adoption of color TV, or music on CD, or video on DVD, the publics exposure to the new technology will create demand where once the established industry players thought there would be none.

The iPhone In My Office

I’ve said many times that I would never buy and iPhone. Well, true to my word…I didn’t….yet one graces my desk anyway. A co-worker gave me his older 3G after he upgraded his family to a set of shiny new iPhone 4s. Call it an effort at recycling.

In truth I have no interest in the iPhone as a cell phone, but I look forward to having an iOS platform on which to try some of the more interesting apps that have been offered. With its built-in microphone the iPhone 3G is, for me, a better option than an iPod touch.

HDVoice In Support of Radio: Tieline At TAB 2010

Some would say that HDVoice is my major passion. I’m not sure that this is true, but I will admit that I grow increasingly dissatisfied with the quality of PSTN audio I encounter in the course of life.

I am especially aggravated by radio & TV stations that use the PSTN to pass production audio. It’s as if they simply don’t care about the technical quality of their broadcast. Why not just give every reporter an old Sony Walkman style cassette recorder? That would actually sound better than a phone call in many cases.

I accept that for call-in style radio shows the PSTN is still the primary means of connecting to the audience, and many people will use cell phones as a matter of convenience. Given these facts audio quality is going to be variable…never great…and often very bad indeed. However, for cases where there is a reporter the field, or passing audio between remote studios, there are much better options.

Last month a reader question prompted a short investigation of how you might leverage wideband (HDVoice) telephony in support of a podcast or online radio show.

This past week I was tasked with working a booth at the Texas Association of Broadcasters annual convention and exhibition in Austin. While at the show I stumbled upon Tieline Technology, a company that makes IP-based wideband audio connective gear for radio & TV stations.
