I've seen that a lot of you are getting better results with the AVR compared to the APP. I would have assumed that the same calculation algorithms are used regardsless but obviously this isn't the case.
Would you say that the results from the APP has improved as the app has been updated?
With the app, you still use the regular Audyssey Mic connected to the AVR, right?
Is the app stable (not crashing that is) on iOS?
The app is stable on iOS. I never had many problems with crashing. Mostly I would just lose my connection to the receiver and have to start over with calibration procedure. However, the last time I used it, it worked great.
I would say the app improves with each release but that it still has a few issues that prevent it from being used extensively.
1) It has a fixed roll-off of frequencies below 20hz. Many like myself don't want that because our systems are capable of delivering clean sound below 20hz.
2) The editing of target curves is fairly crude and needs to be more accurate. This isn't a deal killer just an inconvenience.
As for your question of if the app uses the came algorithms for correction, I don't think anyone can answer that. Only the programers and designers know what they use and it is proprietary.
The app will probably just get better over time and is a nice option to have but not essential. Regular AVR MultiEQ works pretty well and if you need anything more, then there are lots of third party options.
Yes, the mic that is included with the AVR is what you use for the app as well.
