[Discuss-gnuradio] Restoring signal after FFT-IFFT

[Maicon Kist]

Hi list,

I'm trying to recover a sound after passing it by a FFT and a IFFT. The problem is that after the IFFT (to recover the original sound) and sending it to the audio sink, I hear only wheezings.

Attached to this email is the system that I created using the GNU Radio Companion tool.

Do your guys have any suggestion to recover the sound correctly? I think that maybe is something with the sample frequency.

Thanks.
