PIC issues... Linking statically to speex when generating a shared library..
...tion doesn't belong here).
Here's how I link statically to libspeex now in the plugin's Makefile.am --
which intermingles PIC code (the non-library source in the new shared
library) and position dependent code (libspeex.a):
codec_speex_la_SOURCES = PlgSpeex.c speex_nb.c speex_uwb.c speex_wb.c
codec_speex_la_LIBADD = @SPEEX_ROOT@/libspeex/.libs/libspeex.a
codec_speex_la_LDFLAGS = -module -avoid-version
(which, I just spotted, will not be correct for installed versions of speex
-- only ones we build -- since installed versions will not have the .a in a
.lib directory -- but in...

FFT Resampler
...had serious problems
interpreting my results until it dawned on me that the signal
differences were just 0 or 1. So, after a lot of scratching my head,
these are done comparing the result from the _float versions (which is
how both resamplers work internally anyway).
What I did was this:
Load speex_wb.wav as one large chunk of data.
Pad data with as many zeroes as there are samples.
Convert to long double.
Use one long double FFT for the entire thing.
Insert or chop off zeroes so the new length is
(input_length)*(sample_target)/(sample_source)
Use one long double iFFT for the entire thing.
We...
