I’m working on a thing where I’m planning to take a soundmass and split it into vertical / spectral parts – for example, a slice from 0-100hz, 100-300hz, 300-600hz, 600-1000hz, 1000-5000hz, 5000-10000hz, 10000-20000hz, or something along those lines.
(Then do various time-based etc processing to each layer to taste)
The approach I’m taking is to include an overlap/bleed between sections, with a bleed tuned so the basic reconstruction when stacking the sounds back together is reasonably transparent. Eg, no audible notches at the seams. For my project it’ll be nice if the original sound can reassemble untreated, since I just want to do things with the splits sparingly.
That’s the plan anyway. It seemed like a reasonable topic for discussion, just curious if you all have approaches to this sort of thing that you like – filters all the way! analysis/resynthesis all the way! etc – or find a set of tools or particular workflow useful when operating on vertical slices of the sound spectrum like this.
My filter tool of choice for this particular project is just going to be sox, but if I don’t like the results I might give SPEAR a go and get a little more creative (and manual) with the slicing.
(Edited because I used the word horizontal to describe a vertical stack of frequency bands. Derp.)
