Trouble saving FFT~ data with sfrecord~...

Anthony Palomba's icon

I am trying to save fft~ data to disk using sfrecord. When I
save the data to disk and then read it back in to ifft~ it
comes out sounding different. I am setting the
sample format to float32 when I write the file but it does not
sound the same. I was wondering if someone could take a look at it
and give me some ideas. I have pasted what I have below.

The example you sent is complicated. I guess I am trying
to do something simpler. I know I have an ftt~ that produces
data, that when sent to ifft~ will resynthsize the sound.
What I don't understand is why sfrecord~ is not recording
the data that is being given to it. Are you saying that the
latency involved in writing things to disk causes sfrecord~
to drop data? Could it be inserting silence at the beginning?
