Hi everyone.
I just started using GRC for a college assignment, but I'm having a hard time
to find what I need to know in order to do what I want.
I want to make a flowgraph that works with a limited sample, like a WAV file.
So I'd like to know how to stop the flowgraph after the processing is do
Thanks for the replies. I played a bit and was able to generate a WAV file and
listen to it. However, there are some things I still want to know.
I can play the generated file in VLC, but I can't play it in Audacity or see
it's waveform. I'd like to see the waveform to see stuff like noise. I tri
Hi everyone.
I'm trying to pass an audio file through FFT and IFFT, and the resulting audio
is being distorted. I searched about it and I only found this link:

I did as suggested and divided the signal by the FFT size after t

Hi everyone.
Thanks for all the replies on my previous thread. I did some tests and found
out that the FFT and IFFT do not add noise to my audio signal. It works
perfectly! The noise is coming from another part of my flowgraph.
Before I introduced the FFT and IFFT, I was working with an audio sig
I just realized that float to bits is also acceptable, as long as the samples
don't lose precision.
I didn't tacked this by scaling the samples then converting to int because I
don't know what is the range of values for the outputs of the FFT and IFFT
blocks.

Yesterday, during the night, I tried my luck on the #gnuradio IRC channel. One
was kind enough to point me in the right direction. Up to this point I
had no idea I could connect ports of different types. So, starting from the
FFT's output, I connected that to a complex Vector to Stream, as one
