Hi, first of all, I am a huge fan of Right Mark Audio Analyzer.

I was wondering what would be the optimal bit depth/sampling rate setting for a DAP(mp3 player) measurement, especially for the players with 16/44.1 playback capability. (e.g. Apple iPod) I have seen many RMAA data of DAPs, and their input settings varied in a great degree.

191x56, 0,6Kb - 191x56, 0,6Kb - 191x56, 0,6Kb - 191x56, 0,6Kb
Should the bit depth/sampling rate settings of the input(soundcard) and output(DAP) be matched? Is it appropriate / Does it matter to go beyond 16/44.1 (e.g. 24/48 or 24/96) to measure such mp3 players?

Set the same mode for recording. You may set 24 bit, but it's useless. But you should avoid non-equal sample rates, because of tests will be placed in different time moments and for FR test sine tones will be in other points. So test result will be incorrect.

I humbly thank you for sharing your great technical insight, Mr.Liadov.
