How To Connect A Google+ Hangout-On-Air To a Conference Bridge: Part 2 – Interconnection

It’s worth noting that a Google “Hangout” is not the same as a “Hangout-On-Air.” A Hangout-On-Air is streamed and recorded via YouTube in real-time. This gives it the potential for much greater reach. A normal Hangout is not streamed in this manner, although it does allow for PSTN connectivity.

This difference is arbitrary, although I’m told it stems from legal concerns about copyright issues that could easily occur if Hangouts-On-Air were allowed to have broad interop capability.

The fact that the VUC uses a Hangout-On-Air has compelled my search for a reliable, high-quality means of interconnecting the Hangout-On-Air and ZipDX conference bridge. Given my long-standing and vociferous support of HDVoice even the PSTN access provided by a plain vanilla Hangout is troubling. Connecting via a pure IP means, like SIP URI, would allow interconnection with much better audio quality.

Considering Opus Implementations

Opus-over-skypeOpus promises to be a great tool for online audio. In technology, as in music, not all opus are implemented equally. Allow me to explain.

Earlier this week I happened into a Twitter exchange with Mike Phillips. Mike is a podcaster. VUC founder Randy Resnick has introduced us once before. Mike is seeking a replacement for the role that Skype plays in his online toolbox.

It came to light that Mike has tried to leverage various soft phones, even giving some focus to finding one that implements the Opus codec. Opus is after all, open source, the current state-of-the-art in audio codecs, and a new IETF standard. However, in Mike’s attempts to tap its potential he has to date come up short relative to Skype.

Auphonic: A Free Online Tool For Automatic Audio Post-Production

auphonic-logoOpen source guru Randal Schwartz of FLOSS Weekly recently interviewed Georg Holzmann of Auphonic.com about their new online service for post-processing audio files for podcasts. Auphonic.com sounds very interesting indeed.

In the past the routine production of the VUC podcasts involved the use of The Levalator from The Conversations Network. That program, while a potent tool, is run locally and limited to processing uncompressed WAV files. This places a certain burden on the user to know how to create the appropriate source files, and later on to encode the processed files for publication online.
