If you only want to playback the data, then the easiest way might be just to change pd's sample rate to 256hz. 

If that doesn't work, maybe have a look at readsf~ help to see how to manually set playback parameters

well, i want to use the EEG data as control data for an audio signal, so lowering the samplerate is no option..
the help from readsf~ doesn't say anything about changing the samplerate.. (but shouldn't it just read the right samplerate from the file? it's a normal .wav file..)

i tried running it from a subpatch with a lower samplerate, but that didn't change anything..

i will give that a try. thanks for the suggestion!

Hi,

I'm trying to play back a rather uncommon file with readsf~. It's 3 hours of EEG data, on 28 channels, with a samplerate of only 256 hz. At first sight, readsf~  deals well with the 28 channels, but it seems to play it back way too fast.. Is there a way to make rit play back the file at the right speed?
I'm using Pd version 0.40.3-extended on windows xp..

thanks!

Kristof
