i'm trying to load some large files into baudline
(16-bit/stereo/48000hz/1 hour long), but i can't seem to load in the
entire length. i've set the max capture time as high as i can get it
(23m18s), but that stops increasing when the buffer size exceeds
224MB. (overlap at 100%)

file too big for 100% overlap case, truncating s=67106816
error, load_padding = -6281216 < 0, ss=2048 pl=29700 ws=67106816

max capture time
This is the maximum amount of time in hours, minutes, seconds
(HH:MM:SS) that the circular wrap around buffer can hold, without
wrapping and rewriting the data first recorded.  Many things affect
this value: the overlap percentage, the amount of buffer space, the
number of channels, the color bit depth of the graphics plane, ...

As a work-around try doubling the FFT transform size which will double
the maximum file load size.  Doubling the FFT size will double the max
file size all the way up to 2 Gsamples (12 hours at a 48000 sample
rate) if you have enough memory.

Note that you can use the "Hz scaling" feature to zoom out and reduce
the visual size of the Spectrogram, Spectrum, and Average windows when
the FFT's are wider than your screen.  That way the visual width of a
8192 point FFT can be the same as a 2048 point FFT.
