Author Topic: A-B Chain with software and laptop? Todd Cornwall Film Handler Posts: 91 From: Madison, WI Registered: Feb 2004 posted 09-26-2010 04:56 PM                     I was just wondering if any of the oscilloscope software out there is useful enough to actually use with a laptop to do A-B chain adjustments? I had hoped to pick up one of the new tablets coming out for a portable and easy way to do checks. I'm guessing that using something like an iPad is out since 1) It's apple and 2) There really aren't any inputs to speak of, but HP and other companies are coming out with similar devices. I think there is one coming out based on the Android system as well. My phone has an RTA (android), but I'm not sure how accurate or useful it is. I just got the free trial to look at it. Any ideas? Suggestions?  |  IP: Logged Rodrigo Martins Film Handler Posts: 2 From: Além Paraíba/MG, Brazil Registered: Aug 2010 posted 10-19-2010 10:55 PM                     AudioTools from StudioSixDigital with iAudioInterface is a very serious set. Works with iPhone and iPad. I used to work with SIA SmaartLive on a Mac and now I can do the very same job with this set.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It has all of the scope functions you need for an A-Chain as well as the best B-chain tool for cinemas. -Steve  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Don't think it's fast enough and I have an alternative or two.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 10-20-2010 01:35 PM                       Yeah, even the most basic phosphor screen analog scope works better than digital apps. for some purposes.  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 10-20-2010 01:45 PM                     You can snag a used Tektronic scope for $100 on eBay if you look around. It'll do everything you want it to do. You can't beat that price with a stick! What's the iPhone app cost compared to a used scope?  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 10-20-2010 01:47 PM                     I used to carry around this Abacus ARTA 600 Audio Analyser The ARTA 600 is a 30-band one-third-octave audio spectrum analyser adapter that uses a separate oscilloscope as a display. Uniquely, it permits the frequency response to be viewed at the same time as the relative phase (azimuth) of the left and right input signals. Manufactured between 1980 and 1994 it was used by cinema sound installers around the world. Yes it was a pain to carry my scope, analyser, tools, laptop, any parts I was replacing. But it got the job done. quote: Manny Knowles fancy digital tektronix scope An ASC tech had one and I didn't like it, I tried using it during one install and gave it back, it was a pain in the ass to work with.

Too funny dude I picked up a couple of these on EBay for about 100.00 a pop. Leader LBO-325 - 60Mhz Oscilloscope These are very small and work well for A chain analog and digital alignment.  |  IP: Logged
