For anyone building applications with audio for these platforms, having these tests done can be absolutely useful.
While what you decide to put in it is up to you, I consider important to at least have a straight notion of what your audio content will sound like through the iPhone or iPad tiny speakers.
After recording a 10 second sweep through the mentioned devices (many thanks, F.!) following Aaron Brown Sound article, I deconvolved the signals with Voxengo Deconvolver. For someone doing the same, I advise to keep recording steady silence for two seconds after the sweep is over.
Below you can take a look at the difference between pink noise generated at 0 dBFS through and without the resulting iPhone 5 IR imported to Waves IR-L.
Please keep in mind that this isn’t an all-purpose flawless test. Usage of the iPhone and even little issues related to manufacturing have their influence.
