Reality Check: Computer Speakers vs Hi-Fi

Lower East Side Air Overview This morning’s news dump finds me distracted by an Engadget story about Audyssey releasing a new AirPlay-capable powered speaker system called “Lower East Side Air.”

This is the second time such an announcement from this company has caused my brow to wrinkle. The first time the company caught my attention was when Tech Crunch reviewed their Lower East Side Media Speakers.

Going beyond the press release I had a look at the companies’ web site for some greater depth on the Lower East Side Air product. I was surprised to find that there really wasn’t anything more to be had.

Deep Geek: Audio Beam-Forming In The Real World

Have you ever encountered something that seems a little odd, then find that you are in fact surrounded by examples if it in your daily life. So it is with “Beam Forming.” You may never have heard of it, but it’s all around you, and it’s more than a little interesting.

Wikipedia tells use that, “Beam forming is a signal processing technique used in sensor arrays for directional signal transmission or reception.” It is essentially a way of using an array of omnidirectional sensors to synthesize directionality.

Cast into the audio domain beam forming is a way to use the signals from multiple omnidirectional microphones to create the equivalent of a direction microphone. Further, since the process is based upon signal processing, it can be variable. It can create the equivalent of an electronically steerable microphone, complete with the ability to “zoom” in or out. It’s not unlike a zoom lens for sound.

Sounds cool, right?

HDVoice In Service Of Online Radio: Part 3

Sometimes the simplest questions result in the most interesting path of investigation. So it has been with Soljon’s initial question;

I am looking for an IP phone that supports G.722 and has audio inputs / outputs so I can connect it to my mixer. We are trying to connect two studios together for an online radio station. I have yet to find anything other than high end Polycom gear that has something like RCA in/out jacks. Have you by any chance come across anything?

USB Audio Interfaces: Mac vs PC Applications

If you’ve been reading here for a bit you’ll know that I like my Plantronics .Audio 615m headset. I heartily recommend the Plantronics .Audio lineup for people who need a headset for use with a soft phone.

Since back when this review was published I’ve heard a couple of times that people have had issues with the Plantronics .Audio line not working correctly on Mac systems. Most recently this comment was posted to the review:

Thinking Outside The Box: SIP Hard Phone + External Speakerphone

I find that I’m simply drawn to novel and innovative approaches to problems. In the VUC post-call ramble this past week Michael White of E4Technologies described something that’s stuck in my mind as being pretty cool.

He was working with a large-company-who-shall-remain-nameless on a very significant installation. It was going along well. They had selected a line of SIP hard phones from a large, well-known  manufacturer, and were generally happy with the results. That is, happy with one exception; they didn’t like the performance of  the speakerphone on their chosen model of desk phone.
