Automatically splitting audio file into 32 equal frequency bands?

Hello,

Does anyone know if it is possible with any version of Adobe Audition to automatically split an audio file into 32 equal frequency bands, and save each band separately as a different file? If this is not possible with Adobe Audition, could you suggest the piece of software that is capable of doing this?

Sharp cutoffs between bands would be preferable.

Thank you!

There is probably a way to do some of this via script, which will require a different kind of expertise than I can give.  There is a quality question involved here: filtering invariably introduces some alterations to the signal.  That is, if I make that 32-way split, then sum all the resulting files back together, will the sound be the same as the source?  Usually the answer is no.  In all previous versions of Audition (1.x - 3.01) there is an effect available in Multitrack View called the Frequency Band Splitter.  When set to a high FIR filter size, the separation between bands is still hardly "brick wall," and in the bass range rather sloppy.  The benefit is that when the files are summed back together, they perfectly match the source.

You didn't say if you're trying to do 32 log bands (like a third of an octave) or linear.  The latter would work better because it would give you wider bands in the bass range.  But probably not too practical.

Another thing you might do is to use the Splitter with multiple passes.

Why are you trying to do this?
