looking for vsts based on discrete wavelet transform

Post by kensuguro »

I'm looking for a way to get my transient processor better. Mainly in the context of busy mixes where it's easy for transients to be masked by other sounds, like a loud lead vocal. (any loudest thing in the mix drives the dynamics processing.. not broken, but I want it to be smarter) So anyway, I was thinking of going a multiband approach, initially thinking I'd just pop in a short term fourier transform to break out into bands, do the dynamics processing just where it's needed, and then reconstruct. Seems that's been done, although the "dynamics" processing is done in more of a traditional comp fashion:
http://www.voxengo.com/product/soniformer/
http://www.meldaproduction.com/mspectraldynamics

So those are similar in approach. STFT's kind of a mixed bag though, since there's the freq resolution vs time resolution tradeoff, and that seemed particularly ill suited for transient processing, which are innately super fast. I know from experience that just doing a vanilla STFT analysis-resynthesis (no manipulation) on drums really sucks the life out of them. Then I found continuous wavelet transform, which seems to progressively change the band parameters so that you get more freq resolution a lower frequencies, and better time resolution at higher frequencies. Which totally makes more sense to me than STFT's fixed params for all bands approach. (though there are workarounds) Considering it's more akin to convolution, it doesn't sound too exotic to me.

I wanted to see if there were any VSTs that advertise the use of some sort of wavelet transform and reconstruction as a means of doing spectral manipulation. I realized it's hard to be that specific, since most developers would go as far as using the word "spectral", but not really go into much more detail. (who cares, right, or why share the secret sauce?) Was wondering if any of you know of a plugin that specifically uses wavelet transforms. I found a paper on a VST that uses segmentwise discrete wavelet transform, but it's like a thesis project. (https://www.vutbr.cz/www_base/zav_prace ... e_id=59812)

Mmmm, don't know..., but perhaps there is something similar in here:

Sorry if I don't give you something specific Ken, I'm just guessing from things I have seen around there a long time ago that may be related to what you want.
