Guide for idiot to testing ipod with RMAA needed, Brief but enough Options

[4sure]

Hi there. Can someone a little bit bother to explain (briefly) how to measure ipod etc. with RightMark Audio Analyzer?

It is rather trivial, actually.

• Generate a 16 bit / 44.1 kHz test signal and calibration signal .wav files with RMAA. Put those .wav files on the iPod.
• Connect the iPod to the line input of your soundcard. Use either the headphone jack or the Line Out Dock with a special cable.
• If you decide to use the headphone jack, you might want to measure the iPod with a "load", i.e. with headphones attached. You'll need a 3.5mm jack splitter for that. Connect the splitter to the iPod's headphone jack, plug the headphones into the splitter, as well as the 3.5mm male-male cable from your soundcard.
• Disable all sound processing features on the iPod (EQ).
• Set the volume on the iPod to the maximum (0 dB, I don't think it goes higher, so it shouldn't clip). Skip this if you're using the LOD.
• Play the calibration .wav file on the iPod and record it with your soundcard, using any audio recording software (e.g. Audacity).
• Repeat the previous step and adjust the recording volume on your soundcard until the recorded wave is close to 0 dBFS (but don't go too high and make it clip!).
• Play the test signal on your iPod and record it with your soundcard.
• Load the recorded test signal .wav file in RMAA (not the one on the iPod).
• Export the results as HTML + images
