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.
