Welcome to the Rockbox Technical Forums!
Sampling rate is probably wrong.
Well, I have certainly seen files that play fine on a PC, but have sampling rate problems as evidenced by abnormally high pitch. Did you explicitly set the sample rate?
Limited audio samplerate - audio must be sampled at 44.1KHz, other samplerates will play, but at the wrong speed.
WinFF (FFMPEG) Doesn't allow for 44khz encoding (at least that's what the program itself has told me)
Note: 44khz is DIFFERENT from 44.1khz, that extra .1 is VERY important. If you try typing in an invalid value (like 44000 instead of 44100) it might in fact reject it.

But please, in the future, if you can't convert a file the right way, ask how to convert it the right way FIRST. Don't say "My improperly created file doesn't play right, what's wrong with Rockbox?"
You said "mpegplayer plays lower pitch." Mpegplayer == Rockbox. Lower pitch == Wrong. Therefore "Rockbox plays wrong". What word did I put in your mouth, exactly?
Anyway, the presets resample to 44100. If you'd used the presets, and not tried to override anything, you'd be fine. You said you used the presets, did you never try them without inserting your own values? If the presets aren't working, it'd be useful to know so we can check on that but I need to know if you tried them without manually inserting wrong values.
