Below is Rightmark's summary of the results plus a modded quote for my 3GS's results.
A. iPhone 3GS headphone output.
B. EMU-0404PCI 44kHz/16bit analog loopback. As a CD resolution reference. Same test conditions as the iPhone.
C. This is a perfect 44kHz/16bit test result (same as a digital SPDIF output).
D. This is a 44kHz/24bit ANALOG loopback test to show the input's maximum performance when testing a device capable of high resolution formats. IE the output from the soundcard used to do the loopback test
The separation spec seems to have dropped but that could be due to the new mini jack to RCA cable I am using. Might be flaky, might not. I'll report back on that one.
But then there's this.......
Look at that spread on the base of the fundamental? WTF?! Gonna look into that one as well.
I'll can provide a file share link to an HTML file that contains the complete results, if anyone is interested.
