well, i want to use the EEG data as control data for an audio signal, so
lowering the samplerate is no option..<br>
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..)<br><br>

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

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

<dd>Hi,<br><br>
<dd>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?<br>
<dd>I'm using Pd version 0.40.3-extended on windows xp..<br><br>
<dd>thanks!<br><br>
