Hi all, im trying to use baudline under ubuntu (64b) 11.04. 3gig ram

no matter what flags i give related to memory i get the same limited
to 25-30 secs opened file:

file too big for 100% overlap case, truncating s=67106816
error, load_padding = -7141376 < 0, ss=2048 pl=29280 ws=67106816

this is the line im using:

LD_PRELOAD="/usr/lib32/" /home/alejo/Desktop/tx_rx/
baudline_1.08_linux_x86/baudline -fftsize 4096 ../.wine/drive_c/

then go to scroll control but no matter what i only get 59secs.

what am i doing wrong, how can i open a longer file for analysis?

thanks in advance for any tip.

below a prev email that helps as reference on the same topic

What sample rate is your data? It must be fairly high for only 59
seconds of it to fit.

Try using a larger FFT size which will make the 100% overlap case
