What format is this function in? 0-255 could mean anything.
Wouldn't it make more sense if it was in as the playback rate, as in, 44khz and the like? |

| hm... frequency goes from 0 to 88000 if you believe the music test script... so I'd guess you use 44000 (or 44100?) for 44khz... |

I've got an idea.
What U need is to
1. generate a wave file with a 1kHz sinewave inside.
(use Goldwave or send me a mail, I'll make it 4u)
then, by
2. playing back this wavefile on the PSP with different parameteers and measuring the freqency we can
3. re-estimate the sampling frequency the particular parameter corresponds to.
ie. example:
20 ~ 8kHz
40 ~ 16kHz
60 ~ 24kHz, etcetc |
