[LAD] Zita Resampler unexpected output

[André Garnier Coutinho]

Hi Guys!

I was doing some tests to learn how to use zita resampler and I got an
unexpected output. All the last positions of my output vector were 0 and I
don't know why.

I have copied the main files of zita resampler to my home directory. The
files were resampler.cc, resampler-tables.cc, vresampler.cc and their
respective headers. I have done this because I will need to modify the
source code to use it with double precision vectors.

Does anyone know what I am doing wrong?

I'm trying to do this to improve mod-DS1's performance.

I'm attaching my code.

greets
