    Thank you for sharing Aaron. For most of us that don't have access to non open source papers, this is gold!

    Thank you for your work, those who like synthesizers circuits like me and many others will surely appreciate your paper. Ty for the public download of the paper and matlab code

    But inverting the phase makes a really unique response curve. This makes it awesome and worthy, and most likely merits further investigation. I’m sorry that other academics don’t see the novel and fascinating aspects that you have shared with us.

      The interesting thing is that inverting every-other band makes the response *flatter*.

      @@Lantertronics I wonder what each one sounds like. Is the phase "issues" with not inverting not as pleasing to the ear as inverting every other one? Great stuff.

    That is a very interesting circuit indeed.

    Great paper! I've never seen this topology either; a sort of bastard child of a Twin-T and a tilt control.
    "Lack of novelty" is such a BS criticism that all journals make. A paper that proves sun spots have no effect on coffee sales is just as important to science as a paper that shows sun spots cause increase in coffee sales, yet no journal would publish the former. An explanation of something old is just as valid as an explanation of something new. 'Science' journals are just as guilty of headline-chasing as any tabloid newpaper.

    I AM interested in your paper, so I downloaded it. I am also interested in this discussion about inverting vs non-inverting every other band. Taking a look at the 295 comb filter, I see that it adds up all separate bands. Other filter banks often sum the even bands and the odd bands separately. So, I wonder what it does to the stereo field if panning the even bands to the left, and the odd bands to the right. If you don't invert every other band, I expect that there will be 'holes' in the spectrum in the middle. If you do invert every other band, I expect that it may sound more 'mono'?

    But inverting every other band is the logical thing to do. Given the phase plot of any bread-and-butter filter you will always get 180 degrees phase differences in the transition between the bands if you don't invert.
    So, that is nothing to write home about (not even in a nice paper).
    The topology itself, well that's a different thing. Much more interesting.

      It looks like a lot of filter banks *don't* invert every other band, though.
