FFt spread count

I cant get to have more than 512 spread when I try to have higher value it just stop sending the value.?why?

it seems to be connected to the buffer size.

i used an AudioIn node and changed the buffer size to 8192 bytes (doubled it).

after that i was able to use the fft with spread count 1024 (doubled it).

yes, it depends on the buffersize, and also on the stereo/mono setting of the AudioIn.
