Musing About Logitech’s Squeezebox, Squeezebox For Android, Pandora & Tivo

Squeezebox-TivoHD-SB-For-AndroidAround the house and office we use Logitech’s recently defunct Squeezebox music players. We have several of these, a mix of the Squeezebox 3 and Squeezebox Touch models.

There’s an Android app that provides remote control of these little players. I’ve had it loaded for as long as I’ve had an Android phone. However, it’s never worked for me. At least it didn’t until the past weekend.

Being something of a traditionalist I have historically fed the Squeezebox herd from a small media server or NAS on my network. Only occasionally would I point them to online sources like Radio Paradise, KPFT or KUHF.

This past weekend I started to play with Pandora. The Squeezeboxes can access a Pandora account and thereby stream decent quality music from an online source. Pandora’s paid service provides 192 kbps streams without advertising. That makes the $36/yr paid service seem quite attractive.

Millions of people already use Pandora. I accept that I’m late to that party.

Dev-Audio’s Microcone: A Novel New USB Conference Microphone

Many thanks to self-described Blogalyst Dave Michels for pointing out a new usb conference microphone from Dev-Audio called the Microcone. Featuring six microphones and some on-board DSP this little device is purportedly able to capture the directional cues inherent in a meeting.

The company sells a related OSX application that is said to record six tracks in parallel. Each track corresponds to one of the size directional microphone pickups.

According to the companies web site:

“Microcone® uses innovative intellectual property based on microphone array techniques. Microphone arrays consist of multiple microphones functioning as a single directional input device: essentially, an acoustic antenna. Using sound propagation principles, the principal sound sources in an environment can be spatially located and distinguished from each other. While the Microcone device can be understood conceptually as a single intelligent group microphone, in fact it is a microphone array device containing several microphone elements acting in an integrated manner.”

They’re leveraging acoustic beamforming, something that I have mentioned a few times in the past.

Defining HD Voice vs HD Audio

Earlier today Doug Mohney of HDVoiceNews issued an interesting tweet;

Briefing with Tier 1 telco on #HDvoice. Product manager started using the useless marketing term #HDaudio. Maybe should use #HDtelephony?

I find myself agreeing with Doug’s assertion that “HD Audio” is not appropriate terminology. “HD Audio” is way too broad a term, and more appropriate used with respect to entertainment than telephony.

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.

CSR Wireless Audio Platform: Why You Should Care

A few days ago CSR, a company based in Cambridge UK, issued a press release highlighting the fact that their BC6145 chip was used by LG in the new HBM-260 Bluetooth headset. Normally consumer Bluetooth headsets are just one thing….dull. However, you might just give this news a look because there’s something interesting behind the headlines.

Your presence at this site indicates that you have at least some passing familiarity with the phenomenon that is HDVoice. Over the past couple of years I’ve worked to find HDVoice capable tools for my own use. I started with soft phones, but then went on to explore SIP hard phones and eventually accessories like headsets. Often I was startled and frustrated by the complete lack of suitable products in the marketplace.

Getting Close To A Yeti

Blue-Yeti-200 My ongoing involvement in the VoIP Users Conference has me occasionally pondering my home office equipment. While I make my living in the broadcast television equipment business, in truth, audio was my first love.

The VUC can easily be joined using any phone, but sometimes a phone…even my long-time companion Polycom IP650…doesn’t feel like the right tool for the job. So last year I put a microphone on my holiday wish list, the Yeti from Blue Microphones. Seeing an opportunity to address the my voip-geek habit, my wife decided to put one under the Christmas tree.

The Yeti is in many ways special. It’s a USB-attached microphone, so it plugs directly into a computer. That means that the critical electronics of the pre-amplifier are housing in the mic itself, away from the harsh electrical environment of the computer’s internals.

Further, the Yeti has three microphone capsules under it’s wire mesh head. The output of the three capsules can be mixed in various combinations resulting in several directivity patterns; omni-directional, cardoid, stereo (left-right) or figure-eight (front-back.) This makes the Yeti very adaptable to different  situations.
