Author Topic: iPhone RTA Jarret Chessell Master Film Handler Posts: 288 From: London, Ontario, Canada Registered: Jan 2009 posted 07-01-2009 05:34 PM                     I recently acquired an iPhone, and I found an RTA application... iPhone RTA The software claims you can calibrate the microphone. I guess I was just wondering if anyone had any experience with this. Is it a total waste of ten bucks? If I were to buy the software I don't have access to a standalone RTA to compare the results. It also says it has a pink noise generator that you can use by plugging into the headphone jack. It might be a little difficult to use for cinema screens, but might be an easy way to check on things.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

There is another app due out for the latest iPhones that will allow one to used calibrated mics and such...seems very promising. If you have an iPhone...it is probably worth while for spot checks and such...again...for $10, how far wrong can you go?

The RTA and SPL apps can be calibrated for level even when using the internal iphone mics. You just need a known calibrated RTA to compare it to in order to set it. i'm still awaiting the calibrated mic they talked about on the release of this app but ihaven't seen it yet... Have fun with yours!!!

However, from time to time i may have access to an RTA to calibrate it. I guess I'll pick it up and fiddle with it until it earns my faith.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-02-2009 08:06 AM                     Check out the SPL meter as well... ibelieve it's cheaper and it's also very useful for checking system balance....

Pretty easy to figure it out too. So far all I've concluded is that my PC speakers have massive pockets in the spectrum...  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 09-26-2010 08:22 PM                 It has been 449 days since the last post.  |  IP: Logged Todd Cornwall Film Handler Posts: 91 From: Madison, WI Registered: Feb 2004 posted 09-26-2010 08:22 PM                     I know its been a while since the last post here, but I'm curious if anyone has tried out the RTA and Scope for the Android phones? I'm curious if they are accurate or not? I really don't want an iPhone at this point and want to stick with my Android  |  IP: Logged Jake Spell Master Film Handler Posts: 294 From: Johns Island SC Registered: May 2009 posted 09-26-2010 11:43 PM                     Iv tried them and they seem to be somewhat accurate, but I have no way to check at the moment. And I have an RTA and SPL, both can be calibrated and were free with the option to buy  |  IP: Logged Todd Cornwall Film Handler Posts: 91 From: Madison, WI Registered: Feb 2004 posted 09-26-2010 11:55 PM                     Cool. I'm wondering how they might be used in a theater environment?  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 09-27-2010 01:36 AM                        Don't forget a good telescope to see the results on the screen, because you ARE NOT just setting that by an open port window!  |  IP: Logged
