[Tetrapol-kit] RP-CELP decoder doesn't seem to work

Hi! I'm testing the latest tetrapol-kit with a TETRAPOL signal (formerly known as SIRDEE here in Spain). I capture well, and decode to JSON, but when I use the rp-celp codec to extract audio, I only get weird sounds.

I don't know if I could send you a sample.

Thanks in advance.
