Isolating audio by spectrum?

Jul 22, 2012 1:34 PM

Sony have a program called "SpectralLayers Pro" which is an audio editor that can seperate audio into layers (I assume based on frequency ranges).

 

I am guessing it applies a sequence of frequency filters to the audio file to create these isolated layers which then could be be "flattened" again to create the exact original (if no changes were made) without any overlap.... am i wrong about this?

 

So I was wondering if this is possible with the tools in Audition? I guess the main thing would be to be able to filter out sections of the frequence spectrum without overlap..?

    Audition used to have the facility to do this a couple of versions ago, but unless I'm mistaken it's still in the features backlog for the new rewritten Win/Mac version.

    I think what Steve may be referring to was the "Frequency Splitter" tool that would break a file into multiple parts, isolating specific frequency ranges in each.  The Sony tool is similar to Melodyne, and attempts to isolate different elements in the sound and filter them into separate "layers" which may be disabled or modified.

    Well, if you didn't do anything to the bands you'd split out in the splitter, you could certainly recombine them without too much apparent damage - but this certainly isn't what the Melodyne system does, as Durin points out. And Audition's certainly never done what that does - unfortunately!

    An Automatic Harmonic Selection tool would be very useful when you have selected the fundamental frequency.
