Auro 3D Immersive Sound

Auro 3DDon and Todd get a demo of Auro 3D‘s immersive sound experience which until recently was only available in movie theatres. The newly launched consumer version of the Auro 3D audio system adds a height component into the sound mix, giving the equivalent of 9.1 sound. Coming from a digital cinema background with over 150 theatres already using the system, Auro 3D is being introduced into home theater, gaming, mobile and automotive markets.

Especially watch this video if you want to see Don and Todd looking like smurfs while discussing the merits of smooth jazz and alcoholic beverages….

LineIn by Rogue Amoeba

I have a Roku player which I connect to my monitor and until recently I had it connected to a stereo receiver with surround sound speakers. Unfortunately my receiver blew a fuse during a recent thunderstorm and right now I cannot afford to purchase another one. I was able to reconnect my Mac Mini to an old set of Altec Lansing PC speakers setup with two front, two rear and a bass speaker. However, I didn’t know how I was going to connect the Roku to it. I was going to connect it through the Aux input, however it would require an adapter to connect RCA cables with a 2.5 mm male 4 conductor cable. This is the one cable or adapter that I don’t have. Then I remembered that the Mac Mini had an audio in connection. I wondered if I connect the Roku’s audio into the Mac Mini input if that would work. When I connected it I could see the audio was coming in under the sound preference, but I couldn’t hear the sound.


I wanted a simple solution that was easy to use. I Googled the problem and found a free app from Rogue Amoeba called LineIn. It is a very simple app. You simply choose whether you connect to the default input or through USB and then do the same thing for output. Then hit Pass Thru and it just works. It sounds great and is super easy to use. According to the Rogue Amoeba site it replaces the “Play input through output device option that was available in OS 9”.

A couple of highlights from the year includes Wireless Surround effects speaker which replaces the rear speakers with single unit. As it’s wireless no cables are required except for power. Available now for $399.

Continuing the surround sound theme, the PolkAudio SurroundBar delivers surround sound from a single unit and pairs well with flat screen TVs to give a big audio experience with minimum of fuss. There’s just one cable from the TV to the speaker. Starts from £349.

PolkAudio also have a range of subwoofers that are wireless ready so they can start off wired and then be converted to wireless with the addition of $99 module. Very easy to use and keeps your investment going for that little bit longer.

Finally, Al talks about the Blackstone TL series of compact home theatre speakers. These are small powerful speakers for home audio that pack a punch and give big sound from a small box. A 5.1 home theatre system runs $499 upwards.

All products are available now.
