I think that that is just the nature of FFT unfortunately, to be able to tell what frequencies there are, the sounds has to have been played to get enough data.

(I suppose it could read-ahead to get the data, but then any audio input would be delayed to allow that)

hi john. i guess so, but since i have been using sonia for quite sometime the gap between one lib and the other is relevant..
sonia takes no time to respond, while ess is noticeable.
its pretty weird actually, since i can get a 2048 sized buffer in sonia and still have good responses..
and using a 512 with ess it gets delayed..
