… graphics tools like blur? And other ways of manipulating the spectrogram?
The reason I ask is that I was just playing with a sound (separated out as Tonal) which has some fairly fast pulsations in it that might be smoothed out using a blur tool. In fact, the whole of this batch of sounds had these artefacts in (my fault for not catching it at the timestretching stage) which i managed to partially eliminate on the ones where it was most noticeable using a spectral blurring vst plug. But my suspicion is that I could probably have done a better (or at least, more controlled) job of this with a blur brush in SL.
